Hallo!
Is there a package in R that does Q-type factor analysis?
I know how to do principal component analysis, but haven't found any application of Q-type factor analysis.
Thx,

Input: A dataset X, kmax: maximum number of clusters, num_subsamples: number of
subsamples.

10- fold cross validation for naive bayes(e1071)
Hallo!

library(e1071)
tune.control <- tune.control(random =F, nrepeat=1, repeat.aggregate=min.,sampling=c("cross"),sampling.aggregate=mean, cross=10, best.model=T,
