# How to Obtain Output of proc fastclus (and proc cluster) as SAS Dataset

Hallo,

Recently, I have to use "proc fastclus" to cluster some data. But I do not know how to obtain the Output given by "proc fastclus" as a SAS dataset.

For instance, I am obtaining the following Output in the SAS Output Window.  Is there a way to obtain the following Output as a SAS dataset ?

I shall be thankful for your time and suggestions.

regards

Ehsan

## Re: How to Obtain Output of proc fastclus (and proc cluster) as SAS Dataset

Hi,

You need to put ods output before proc fastclus syntax. All the desired output datasets will be saved in work library.

Regards,

Naeem

ods output InitialSeeds=InitialSeeds MinDist=MinDist IterHistory=IterHistory

ConvergenceStatus=ConvergenceStatus ClusterSum=ClusterSum  VariableStat=VariableStat;

proc fastclus data=have Replace=FULL  Radius=0  Maxclusters=3 Maxiter=20  Converge=0.02;

var a b c d e;

run;

proc print data=InitialSeeds;

run;

proc print data=MinDist;

run;

.........

......
