I want to import a .txt file in SAS.
Here what looks like my data :
annee manufacturier modele categorie cylindree cylindres transmission ville ...
2016 Ford Focus 1 1.8 5 Manual 10.1
2016 Toyota Tercel 3 1.4 3 Auto 7.1
Here is my code
data car;
infile "C:\Users\Mark\Desktop\sas\car.txt"
LRECL=10000000 DLM=" " firstobs=2 ;
input
annee manufacturier modele categorie cylindree cylindres transmission type ville route combine emissiond indice
;
run;
But, when I run it, I have a lot of " Invalid data for ... " and then I end up with very few data in my table in SAS and lots of missing ones.
Some variables are numbers and some are characters. I feel like the problem is there.
How I could import that type of file ?
Thank you
A text file does not have any intrinsic data type. Everything is character, until you explicitly tell SAS the data type of your columns. Also, sometimes you need to tell SAS the input format, or informat, of your data.
Sometimes SAS is smart enough to guess correctly re: your data informat. For example, the below code generates the same results if you delete the informat statement. But, this would not be the case for say dates. In general, explicitly specifying the informat is best practice.
If your data was delimited, such as CSV, you could use PROC IMPORT to import your data. Using PROC IMPORT, SAS will make a best guess as to the data type based on the content of the columns (like Excel does when it imports text data).
The below code will import the data you specified:
filename temp temp;
data _null_;
infile datalines;
file temp;
input;
put _infile_;
datalines;
annee manufacturier modele categorie cylindree cylindres transmission ville
2016 Ford Focus 1 1.8 5 Manual 10.1
2016 Toyota Tercel 3 1.4 3 Auto 7.1
run;
data want;
infile temp firstobs=2;
length
annee 8
manufacturier $20
modele $20

;
informat
cylindree 8.1
ville 8.1
;
input
annee
manufacturier
modele
categorie
cylindree

ville
;
run;
If your data contained spaces, for example manufacturier = Mercedes Benz, then you would need to use an informat (eg. $char20.) for that column as well.

I tried to import text file in sas with the following code
PROC IMPORT DATAFILE= '/home/u44418748/MSc Biostatistics with SAS/Datasets/school.txt'
OUT= outdata
DBMS=dlm
REPLACE;
delimiter='09'x;
GETNAMES=YES;
RUN;
But I am getting import unsuccessful because text file has period for missing data
this is what i got in SAS log
NOTE: Invalid data for class_size in line 455 16-17.
455 CHAR 454.34.8.32.17.NA.23.125.12.188 31

sl_no=454 school=34 iq=8 test=32 ses=17 class_size=. meanses=23.125 meaniq=12.188 _ERROR_=1 _N_=454
how can load this text file in SAS
Did you create that text file from R? That package has a nasty habit of putting text values of NA for numeric values into text files. If you are the one that created the file the you might check if the system you are using has a way to not put the NA into the file to begin with. In a delimited file missing values are normally represented by having nothing for the field. So the delimiters are right next to each other. For SAS you can use a period to represent a missing value.
I wouldn't bother to use PROC IMPORT to read a delimited file. Just write a data step to read the file. Since it looks like your file only has six variables and they are all numeric the code is trivial.
data outdata;
infile '/home/u44418748/MSc Biostatistics with SAS/Datasets/school.txt'
dsd dlm='09'x firstobs=2 truncover
;
input sl_no school iq test ses class_size meanses meaniq ;
run;
One way to deal with the NA text in the input file is to replace them with periods. Since all of the fields are numeric you can do that easily because you don't have to worry about replacing real text that just happens to have the letter A after the letter N. Here is trick using the _INFILE_ automatic variable that you can use to make the change on the fly while reading the file.
data outdata;
infile '/home/u44418748/MSc Biostatistics with SAS/Datasets/school.txt'
dsd dlm='09'x firstobs=2 truncover
;
input #;
_infile_=tranwrd(_infile_,'NA','.');
input sl_no school iq test ses class_size meanses meaniq ;
run;
You are getting the NOTE: because of the NA value in the class_size field.
What you presume are periods (.) are actually tabs (hex code 09). Look under the period to confirm, the ZONE is 0 and NUMR 9. 09 is the tab character.
Proc IMPORT guesses each fields data type based on looking at the first few rows (default is 20 rows) of a text file. Your file contained only numbers the 20 rows, so the procedure guessed class_size was numeric.
There a couple of courses of action.
Do nothing. Read your log NOTES and know the places where NA occurred you will have a missing value in your data set.
or,Read the file as-is, but add GUESSINGROWS=MAX; statement to your import code
The mixed data type column class_size will be guessed as character and you might have to do another step to convert the values to numeric (a step in which the non-digit values get converted to missing values)
or, Edit the text file replacing all the NA with a period (.). The dot marks a missing value during IMPORT. The IMPORT step will have no incongruities to LOG about.

data want;
set outdata (rename=(class_size=class_size_char));
class_size = input (class_size_char, ?? best12.);

i have a data sales below, and I am trying to send it out via email with .xlsx file attached.
the question is that I want the cell(s) with negative number(i.e. -2.10%, -0.17%) in column 'change' to be red color:
data sales;
input unid $3. map change percent8.2;
format change percent8.2;
cards;
001 100 12.00%
002 509 -2.10%

When using ODS EXCEL the style attribute tagattr can be used to inject Excel specific features into worksheet cells.
In this case, Excel cell formatting can be applied, such that positive values are formatted one way and negative numbers another way.
Review guidelines for customizing a number format, Microsoft Support
A number format can have up to four sections of code, separated by semicolons. These code sections define the format for positive numbers, negative numbers, zero values, and text, in that order.
<POSITIVE>;<NEGATIVE>;<ZERO>;<TEXT>
For example, you can use these code sections to create the following custom format:
[Blue]#,##0.00_);[Red](#,##0.00);0.00;"sales "#
Example:
ods excel file='sample.xlsx';
proc print noobs data=sales;
var unid map;
var change / style=[tagattr='format:#0.00%;[Red](#0.00%)'];
run;
ods excel close;
I need to import data from a csv-file. And I'm able to read everything else but the date. The date format is like dd.m.yyyy format: 6;Tiku;17.1.1967;M;191;
I'm guessing if I need to specify an informat to read it in? I can't figure out which one to use because nothing I've tried works.
What I've managed so far:
data [insert name here];
infile [insert name here];
dlm=";" missover;
length Avain 8 Nimi $10 Syntymapaiva 8 Sukupuoli $1 Pituus 8 Paino 5;
input
Avain Nimi $ Syntymapaiva ddmmyyp.(=this doesnt work) Sukupuoli$ Pituus
Paino;
format Paino COMMA5.2 ;
label Syntymapaiva="Syntymäpäivä";
run;
And part of the actual file to read in:
6;Tiku;17.1.1967;M;191;
Thank you for helping this doofus out!
There is no informat named DDMMYYP.. Use the informat DDMMYY. instead.
Also make sure to use the : modifier before the informat specification included in the INPUT statement so that you are still using list mode input instead of formatted input. If you use formatted input instead of list mode input then SAS could read past the delimiter.
input Avain Nimi Syntymapaiva :ddmmyy. Sukupuoli Pituus Paino;
Perhaps you are confused because there is a format named DDMMYYP.
Formats are used to convert values to text. Informats are what you need to use when you want to convert text to values.

You could use the anydtdte informat, but (as #Tom points out) if your data is known to be fixed in this format, then ddmmyy. would be be better. Also, Tom's advice about using the : modifier is correct, and is preferable to use in most (if not all) cases.

which gives:
I have dataset with dates stored as strings in a format ddMonyy e.g. 19Dec16.
When converting the strings using date7. informat to SAS date, some years are interpreted as 19yy and some as 20yy.
Here is a sample code
data strDates;
infile cards;
input StringDate $;
cards;
31Dec99
01Jan00
19Dec16
31Dec25
01Jan26
;
run;
data convertTest;
set strDates;
format Date date9.;
Date=input(StringDate,date7.);
run;
Running the code today (19 Dec 2016) produces the following results
strDate date
31Dec99 31DEC1999
01Jan00 01JAN2000
19Dec16 19DEC2016
31Dec25 31DEC2025
01jan26 01JAN1926
Dates between 01Jan00 and 31Dec25 are assigned to years 2000-2025 while dates from 01Jan26-31Dec99 are treated as years 1926-1999
Question:
How is it determined if 2000 or 1900 is to added to the year? I suspect it is dependent on the runtime (calendar year when the code is run?) - but I was not able to find any reference to this in SAS documentation.
There is an option, YEARCUTOFF, which depending on your system and version probably has a value of either 20 or 26. See KB note 46368 for more information on the change.
It sounds like you're using SAS 9.4, which means the default is 26: anything from 0-25 will be '20xx' and anything from 26-99 will be '19xx'. You can change the YEARCUTOFF option if that value does not work for your data (or, construct the 4 digit year yourself).
I am trying to read this fixed width data into SAS:
John Garcia 114 Maple Ave.
Sylvia Chung 1302 Washington Drive
Martha Newton 45 S.E. 14th St.
I used this code:
libname mysas 'c:\users\LELopez243\mysas';
filename address 'c:\users\LELopez243\mysas\address.dat';
data mysas.address2;
infile address;
input Name $ 1-15 Number 16-19 Street $ 22-37;
run;
proc print data=mysas.address2;
run;
Got this result:
Obs Name Number Street
1 John Garcia 114 Sylvia Chung 1
2 Martha Newton 45
If I edit the .dat file and manually add spaces at the end of each line until they are each the same length, the code works. Any ideas for code that takes into account differing line lengths (w/o manually entering spaces).
Add the truncover option to your infile statement.
Truncover overrides the default behavior of the INPUT statement when an input data record is shorter than the INPUT statement expects. By default, the INPUT statement automatically reads the next input data record. TRUNCOVER enables you to read variable-length records when some records are shorter than the INPUT statement expects. Variables without any values assigned are set to missing.
