R 工作室插入符号包 pbkrtest

Question

I'm not able to load the caret package in R studio due to the missing of /dependecy on the 'pbkrtest' package. However, the pbkrtest package is not available in R studio Version 0.99.879 (for mac). I updated R studio and all packages already. Here is the error message:

error message R Studio

Thanks!

Answer 1

If you can't or don't want to upgrade R for whatever reason (for example if you are running a SQL Server in-database R), a solution to this problem for me was to install the pbkrtest package from source directly ( package version history ). You can try different versions, but the one that worked for me was 0.4-4. You can install using the following command:

install.packages(path_to_file, lib=lib,repos = NULL, type="source")

where "path_to_file" is the location of your package with the package file name ending in .tar.gz likely and "lib" is the optional parameter for your R library -- if omitted the default will be used.

Answer 2

#This should work!

remove.packages("caret")
#this will completely uninstall caret from your device
install.packages("caret")
