Bjoern,
thanks for your mail. But when reporting problems with a contributed
package, please contact the maintainer first or at least Cc him when
writing to R-help.
The problem below is in the formula method of sigest because the frac
argument gets passed on to model.frame which causes the error.
hello,
I have the following problem setting parameter 'frac' in the sigest
function of the kernlab package.
## executing the ?sigest example:
library(kernlab)
data(spam)
srange <- sigest(type~.,data = spam)
## works fine...
## setting 'frac' explicitly
## (in this case even to the default of .2
