Hello,
I'm training a set of data with Caret package using an elastic net (glmnet).
Most of the time train works ok, but when the data set grows in size I get
the following error:
Error en { :
task 1 failed - "arguments imply differing number of rows: 9, 10"
and several warnings like this one:
1: In eval(expr, envir, enclos) :
model fit failed for Resample01
My call to train function is like this:
fit <- train(TrainingPreCols, TrainingFrame[,PCol], method="glmnet",
preProcess = c("center","scale"))
When TrainingPreCols is 17420 obs. of 27 variables, the function works ok.
But with a size of 47000 obs of 27 variables I get the former error.
¿Could be the amount of data the cause of this error?
Any help is appreciated,
Ferran
