Hello useRs!
So, I have a random question. I'm trying to build a character string, then
evaluate it. I think an example would be the easiest way to explain:
kern.vec = c("rbfdot","polydot")
for( j in 1:length( kern.vec ) )
{
formula = paste("ksvm( ind ~ . ,
data=d.temp[,c(ind_col,dep_cols)], kernel =",kern.vec[j],", prob.model=T )")
svm = eval( parse( text=formula ) )
...
}
The problem I always seem to have is that in the formula, I need to have
quotes around "rbfdot" (for example). But, when I paste the expression
together, it removes the quotes. Is there a better way to do this (or at
least a way around this problem)? My method seems a bit kludgy :)
Thanks for all your help!
Josh
