Error: package was installed by an R version with

问题:

I encountered a package installing problem, where I have absolutely no clue how to manage the situation.

install.packages("C:/Users/Oliver/Downloads/NPRED.zip", repos = NULL, type = "win.binary")
Installing package into ‘C:/Users/Oliver/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)
package ‘NPRED’ successfully unpacked and MD5 sums checked
library("NPRED", lib.loc="~/R/win-library/3.5")

*

> Error: package or namespace load failed for ‘NPRED’:
>      package ‘NPRED’ was installed by an R version with different internals; it needs to be reinstalled for use with this R version

Can anyone help me out on that problem??

Highly appreciated! cheers, olli
