Error : Function found when exporting methods from the namespace ?Matrix?
which is not S4 generic: ?as.vector?
In addition: Warning message:

Dear Jajendra,
Your error message looks to me like R is complaining about an out-dated
version of the "Matrix" package. I think the safest way would be for you to
update to the latest R version (3.2.5) and then update all your installed
packages, including "Matrix" with update.packages().
Please let me know whether this works for you.
Kind regards from Kiel,
Sven

Dear viewers
I get following error while I import "caret " package into RStudio. I
have
imported all required packages beforehand I try this. I have tried the
following two options also, but failed to import the "caret" package:
install.packages("caret", repos=c("http://rstudio.org/_packages", "
http://cran.rstudio.com"))
install.packages("caret", repos="http://R-Forge.R-project.org",
type="source")
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()),
versionCheck
= vI[[j]]) :
namespace ?Matrix? 1.2-2 is already loaded, but >= 1.2.3 is required
In addition: Warning message:
package ?caret? was built under R version 3.2.5
Error: package or namespace load failed for ?caret?
Your kind advice is highly appreciated.
