Reformat datasets

sarahsasuser — Fri, 22 Mar 2013 15:49:40 GMT

Hi All,

I have a dataset from my client that I need to reformat so that I can do some analysis and create some reports with it. It is in Excel in the following structure:

	Chicago		DC
Building	25156	54885	2665
Phase 1	5/27/2011	7/5/2012	3/30/2012
Phase 2	6/30/2011	8/10/2012	4/4/2012
Phase 3	7/15/2011	8/1/2012	4/11/2012
Time from Phase 1 to Phase 3	18	25	12

I want it in this format (I will calculate the time in days myself)

Building	Phase 1	Phase 2	Phase 3	City
25156	5/27/2011	6/30/2011	7/15/2011	Chicago
54885	7/5/2012	8/10/2012	8/1/2012	Chicago
2665	3/30/2012	4/4/2012	4/11/2012	DC

Thanks!

Hi.

Assuming that you can 'unmerge' the cell named 'Chicago' to 'Chicago' 'Chicago', or 'Chicago' 'Chicago1' then this may do what you need:

proc import out = your_data

datafile= "path\data.xls"

dbms = excel replace;

MIXED=YES; *this is important because in the city variable(s) you have dates and building codes;

run;

*now we transpose and use the ID to label the columns;

proc transpose data = your_data out = my_data;id var1;var _all_ ;run;

*clean up the data;

data want(rename = (_name_ = city));

set my_data(where = (_name_ ne "var1") drop = _label_ );

label _name_ = "City";

run;

Let me know what you think.

Thanks Anca, this worked well. However, the City column shows the variables as Chicago, Chicago1 Chicago2, DC, DC1, DC2, etc. Is there a way to get rid of the _# after the city?

Hi.

One way to replace the digits is to use regular expressions:

data want;

set have;

new_city = put(prxchange('s/[0-9]//', -1, city), $10.);

run;

Good luck!

Anca.
