Reshaping data from long to wide: one item's data reading in blank

[rebeccachau]

I have a long-format raw data set sorted by ID and Time (wave 1, wave 2) and 53 items. The code I have written successfully reshapes the data from long to wide, with each item re-coded by ID and Time so that each item's name is then annotated with "1" or "2" to indicate Time/Wave. For example, "GDS1" (item 1 on the Geriatric Depression Scale) then becomes "GDS11" (Time 1) and "GDS12" (Time 2). Strangely, however, the data for item GDS121 (GDS item 12, Time 1) ONLY reads in completely blank. I do not have this problem with any other item. I have checked the raw data file and the data is clearly there. Any ideas what might be happening here? I have copied my code in below. Thanks!

[Reeza]

For setting a list of variables to missing at once you can use

call missing (of gds10);

Though, I wonder if having a 2 dimensional array would't have been better than the multiple array declarations.

[rebeccachau]

Thanks, but my question is why does does one item (GDS121) come through blank with the reshaping when it should have data in it. The item GDS122 (for Time 2) comes through fine. It seems like an SAS bug. ??

[Reeza]

It’s 99% likely there’s a mistake in your code rather than a SAS bug. Without the data I can’t run your code. Also, I’ve done this about 1000 times and never run into a bug, though it is possible there is one.

Since everything is in pairs, you can try searching for the pair of that variable and see if it’s not being set correctly somewhere. Part of the problem with really long code - make it hard to find the mistake. If you show what your original data was or a reproducible example Someone may be able to see the issue. Including at least the log would be helpful. Is there no note about uninitialized variable or something? Or missing? Or conversions?

[Reeza]

Any reason you’re not using PROC TRANSPOSE With two ID variables?

[rebeccachau]

Hi, I just couldn't get PROC TRANSPOSE to work for the life of me! I have attached the data.

Thanks.

This is an already wide data set... Are you going from wide to wider and combining the time only? With two times?

[rebeccachau]

Hi, yes, just going wide on time, Time 1 and Time 2

From

ID Time  GDS1

1234 1 0

1234 2 0

 2345 1 1

2345 2 0

To

ID GDS11 GDS12

1234 0 0

2345 1 0

So, you're reusing variable names that already exist in your data, in particular in RETAIN and that will cause 'unexpected behaviour' at times. So either make sure your KEEP and RETAIN statements are actually correct or switch to TRANSPOSE. I recommend PROC TRANSPOSE, it's infinitely easier.

[Reeza]

For the Transpose like this there's two ways, both infinitely easier than your current approach. One is to merge with a rename.  (Edit/Add) Except in your case you are duplicating names again so this approach could get messy.  It may be worth naming the variables GDS1_T1 to indicate the time specifically or at least an underscore if using this method. 

data want;
merge start (rename = (GDS1 = GDS11 GDS2 = GDS21 ... GDS15=GDS151) where=(time=1))
start (rename = (GDS1=GDS12 GDS2 = GDS22 ... GDS15=GDS152) where=(time=2));
by ID;
run;

The second is a double transpose. First transpose it to a long data set that has the variable name and the time in the column and then transpose to wide again, this time using both TIME and the variable name as the ID. 

I renamed your data sets, but I'm sure you can sort it out. Also note the use of variable lists so you don't have to type them all out. 

proc import out=wideIn datafile='/folders/myfolders/WIDEFORMATDATA1.xlsx' dbms=xlsx replace;run;

proc sort data=wideIn; by ID time;
run;

proc transpose data=wideIn out=long;
by id time;
var ADL1-ADL10 COGTOTSAS CURMDESAS GDS1-GDS15 ME1-ME3 NHP1-NHP5 PEFITTOTSAS PMS1-PMS7 RECDEP SD1-SD8  ;
run;

proc transpose data=long out=wideout;
by id;
id _name_ time;
var col1;
run;

I have a long-format raw data set sorted by ID and Time (wave 1, wave 2) and 53 items. The code I have written successfully reshapes the data from long to wide, with each item re-coded by ID and Time so that each item's name is then annotated with "1" or "2" to indicate Time/Wave. For example, "GDS1" (item 1 on the Geriatric Depression Scale) then becomes "GDS11" (Time 1) and "GDS12" (Time 2). Strangely, however, the data for item GDS121 (GDS item 12, Time 1) ONLY reads in completely blank. I do not have this problem with any other item. I have checked the raw data file and the data is clearly there. Any ideas what might be happening here? I have copied my code in below. Thanks!
