Hi John
I don't get an error message but a warning
write.table(myclara$clustering,"cluster.dat",append=TRUE)
Warning message:
In write.table(myclara$clustering, "cluster.dat",
append = TRUE) :
appending column names to file
Here it is the output of str(myclara), it looks
"strange" to me. I think
"clustering" are integers and "data"
are real numbers
str(myclara)

I can't output the two variables in two different files
without any problem.
Thanks

try
str(myclara)
to see what you have - a data frame , matrix etc
Are you getting any error messages?
I tried your write.table commands and they work okay.

HI R users
With clara function I get a data frame (maybe
this is not
the exact word,
I'm new to R) with the following variables:
names(myclara)
[1] "sample" "medoids"
"i.med" "clustering"
"objective"
[6] "clusinfo" "diss"
"call" "silinfo"
"data"
I want to export "clustering" and
"data" to a new text file so I try
write.table(myclara$data,"cluster.dat")
write.table(myclara$clustering,"cluster.dat",append=TRUE)
Variable data is properly exported but clustering
is not
appended to the
output file.
Please, where is the mistake? is it possible to
export the
two variables in
just a sentence?
thanks in advance
Paco
