Dear Viewers

I find following error after updating R and reloading caret

Error : Function found when exporting methods from the namespace ‘Matrix’
which is not S4 generic: ‘as.vector’
In addition: Warning message:
package ‘caret’ was built under R version 3.3.0
Error: package or namespace load failed for ‘caret’

Kindly advise

Thanking you
