Hello,
If you are using function resamples from package caret, just read its
help page. From ?resamples, section Arguments:
Arguments
x
a list of two or more objects of class train, sbf or rfe with a common
set of resampling indices in the control object. For sort.resamples, it
is an object generated by resamples.
Your x argument is not an object of one of those classes. You are
passing the function a list of 2 numeric values, not an object
resembling the examples in that help page.
Hope this helps,
Rui Barradas

Hello
I am using genetic algorithm for some optimization problem. I executed it
with 2 types of data and get results like
GA=40
GA2=60
When I combine it with resamples
Value=resamples (list (GA, GA2))
It gives me the error
$ operator is invalid for atomic vectors.
What should be the issue here?
Thanks
