I tried to do a cluster analysis proc distance with SAS studio.

I tried to do a cluster analysis. how ever it didn't create a dendrogram. the data set and the SAS code I used is attached herewith. could anyone tell me what's wrong with it?

Many of us won't open attachments, so you will have a  better response if you post your code.

When I run your data step this is the Log:

With that many data errors I would not be surprised that you don't get good output.

One question would be why do you have an & on the input statement after reading the Acc variable?

However the real question comes in the proc cluster code where you use a data set from proc distance that did not include the variable COUNTRY anywhere (and not in the data set chili)

107  proc distance data=chili out=dist method=euclid;
108  var interval (StC NA SP PGH BH LC LS LP NFA FP CC AC SE MS CP CM AS
108! FCI FCM FS FSPA NBF FSBE FBEA FC FSr SC NSF GU PH MLL MLW PHF CWF FL
108! FW FWt FT FPP DFt DFl DFF TSWt FPK Yd);
109  id Acc;
110  run;

NOTE: The data set WORK.DIST has 38 observations and 39 variables.
NOTE: PROCEDURE DISTANCE used (Total process time):
      real time           0.02 seconds
      cpu time            0.00 seconds


111  ods graphics on;
112  proc cluster data=Dist method=ward plots=dendrogram (height=rsq);
113  id country;
ERROR: Variable COUNTRY not found.
114  run;

NOTE: The SAS System stopped processing this step because of errors.
WARNING: The data set WORK.DATA1 may be incomplete.  When this step was
         stopped there were 0 observations and 0 variables.
NOTE: PROCEDURE CLUSTER used (Total process time):
      real time           0.00 seconds
      cpu time            0.00 seconds

If you use ID ACC; in the Proc Cluster code as in the Proc Distance it should work

121  ods graphics on;
122  proc cluster data=Dist method=ward plots=dendrogram (height=rsq);
123  id acc;
124  run;

NOTE: The input data set is a TYPE=DISTANCE data set. For such a data set,
      the procedure requires that the order of the rows match the order of
      the variables.
