error in library(caret)

[avrenli2]

Hello One of my students, who uses a Windows PC, is experiencing the following error message when attempting to open the caret package. We tried multiple solutions, including re-installing R but it didn't work. We would be grateful for your help,

`library(caret)`

Loading required package: lattice

Sorry that this occurred. We exclusively see this issue with windows computers and often when the OS has extra security policies. It appears that the package was unzipped and installed but install.packages() does not verify this. Some times, the OS thinks that the package install is an issue and silently quarantines it.

I suggest using the development version of the pak package. It checks for these specific issues and lets you know if there is an issue.
