OK...that's useful, but can you explain the following sequence of
commands (some output supressed):
.infile str15 disease v1 v2 v3 v4 v5 v6 v7 v8 v9 v10 v11
v12 v13 v14 v15 v16 using "/Users/h/ data/
CollectedBucketsL16.txt",clear
. do clusterk 4
. cap: drop km* <--- added this as you suggest to the do file
. local low = `1' - 2
. local high = `1' + 4
. forvalues i=`low'/`high' {
2. cluster kmeans v1-v`1', k(`i') name(km`i')
3. cluster stop km`i'
4. }
This works...but if I follow it with the same command again as in:
. do clusterk 4
. cap: drop km*
. local low = `1' - 2
. local high = `1' + 4
. forvalues i=`low'/`high' {
2. cluster kmeans v1-v`1', k(`i') name(km`i')
3. cluster stop km`i'
4. }
km2 already defined
r(198);
. display km2
km2 not found
r(111);
If I run it again, it works. However, if I manually drop km* (first
line below) and issue the command again, I get the following:
. drop km* <--- I typed this in
. do clusterk 4
. cap: drop km*
. local low = `1' - 2
. local high = `1' + 4
. forvalues i=`low'/`high' {
2. cluster kmeans v1-v`1', k(`i') name(km`i')
3. cluster stop km`i'
4. }
km2 already defined
r(198);
If I run do clusterk 4 now, it works.
Any suggestions?
TIA,
Joe
