Hi All,
I've read in some data from a CSV, and part of it is incorrectly aligned (I think values from the first 21 columns are deleted when it's extracted from a dashboard, for some reason). More specifically, a block of the observations are being read in as though the value for the 22nd variable is actually the value for the 1st variable, etc. (the values for variables 1-21 have been deleted somewhere along the line). Is there any way that I can shift those values back to their correct placement in columns 22 onward? Obviously, I would prefer to use as much of the data as possible. So, I'm thinking I'd like to write syntax that does something like (region is column b):
if region not in (1,2,3,4,5,6,7,8,9,10,11,12,13) then [SOMEHOW-SHIFT-RIGHT-21-COLUMNS];
Any suggestions as to what goes in the bracketed space?
I've included a screenshot to better explain the problem with the data.
Thanks in advance!!!
Is the shifting in the original CSV file or only in the sas dataset, as the result of importing ?
What code did you use to import the csv file ?
Generally I would use arrays and DO loops to shift data, but it seems that some of the columns are numeric
while others are alphanumeric, and you cannot define array of mixed data types.
Hi,
Good question. The issue with the data exists prior to importing it into SAS and, unfortunately, the data source is resistant to change.
I would be more than open to treating all of the variables as character rather than numeric. Ideas?
Thanks!
I suggest fixing this upstream, ie when you export/import into SAS data.
If you imported a CSV or text file, make sure your import specifies TRUNCOVER to avoid these issues. The default isn't usually what people want.
Unfortunately, changing the data upstream isn't an option. This is how I receive it.
I use missover, not truncover. If I switch to truncover, it throws off even more of the columns.
Thanks!
Can you attach a sample of the original CSV and how it should be read in/look?
Or mock up a representative sample.
Working off theory is slower, if you post some data it makes it easier for us to help you.
Sure thing!
Just as a reminder, this is how the data is delivered to me. I REALLY wish I could change the way it's compiled upstream, but I can't.
Attached is a sample of records. There are 3 types of records:
Because of the shifted values, I might have to treat all variables as character variables and then reformat them later. That's totally okay, as long as I get the data in the right columns.
Thanks!!!
Something like this?
data _null_;
file "%sysfunc(pathname(work))\t.txt";
put '0' @;
do i=1 to 29;
put ',1' @;
end;
put ;
put 'anniv' @;
do i=1 to 9;
put ',2' @;
end;
put ;
run;
data WANT;
infile "%sysfunc(pathname(work))\t.txt" dsd dlm=',';
input @;
FIRSTWORD=scan(_infile_,1,',');
if ^notdigit(compress(FIRSTWORD)) then
input a1-a20 @;
input a21-a30 ;
run;
Modify to suit your data.
Thanks. That's an interesting possibility. Unfortunately, the misplaced data in column start with different words/symbols/numbers (or are missing), so it might get tedious. I've attached a sample dataset to another post, but I'll put it here, too, for convenience's sake.
Thank you!
You may start with attached code, demostrating shifting of variables.
Anyway I see some issues:
- shifted variables shall be missing ( if var1 is shiofted to var10 then all var1-var9 will be missing)
- shifting can overide existing values in target variable
- in my code I checked for _N_, the observation number. You may need change it and adapt to other rules.
- finally, you may need to convert some variables from character type to numeric type
filename sample '/folders/myshortcuts/My_Folders/flat/move_block_data.csv';
/* step (1) assuming first rows are full and ok, shifting no needed */
/* use proc import to get variables names as one row data */
options obs=1;
proc import datafile=sample dbms=dlm out=sample replace;
delimiter='|';
getnames=no;
run;
/* step (2) create a macro variable with list of data variables */
data _NULL_;
set sample end=eof;
length varlist $1000;
retain varlist;
array vx $ _all_;
do i=1 to dim(vx)-1;
varx = translate(strip(vx(i)),'_',' ');
len = length(varx);
put i= len= varx=;
varlist = strip(varlist) ||' '|| varx;
end;
if eof then call symput('vars',strip(varlist));
run;
%put &vars;
/* step (3) import data and shift according to rules */
options obs=max firstobs=2;
data test;
format &vars $40.; /* adapt to maximum var length */
infile sample dlm='|' dsd missover;
input &vars;
array vx $ &vars;
/* shifting data */
if 5 le _N_ le 12 then do;
do i=dim(vx) to 22 by -1;
j = i-22+1;
vx(i) = vx(j);
vx(j) = ' ';
end;
end;
run;
Wow! Thank you so much! I'll give this a shot! Missingness and conversion are okay, and I was wondering about overriding values.
Thanks!!!
Same thing really no?

You just have to customise the input statements.
Thanks! Unfortunately there are several hundred of those records. I'll definitely keep this in my hat for smaller issues!
@kjowers I don't see how hundreds of records make a difference.
@ChrisNZ - I'm just suggesting that customizing the "put" statement for several hundred records could take more time than I have to spend.
