I ran library(caret) a few days ago, and it worked. Since then I've updated Rtools, and now I'm getting some errors I can't resolve through my usual methods
Information below for error:
> library(caret)
Error: package or namespace load failed for ‘caret’:
.onLoad failed in loadNamespace() for 'tidyselect', details:
call: env_get(base_env(), "unlockBinding")
error: object 'rlang_env_get' not found
similar for tidyselect
> library(tidyselect)
Error: package or namespace load failed for ‘tidyselect’:
.onLoad failed in loadNamespace() for 'tidyselect', details:
call: env_get(base_env(), "unlockBinding")
error: object 'rlang_env_get' not found
I've tried install.packages with both
install.packages("tidyselect", dependencies = c("Depends", "Suggests"))
When I did that, I could load tidyselect, but then not caret. I then decided to try the github version of caret: devtools::install_github('topepo/caret/pkg/caret'). This failed with a couple of error messages:
Error in is_list(x) : object 'rlang_is_list' not found
Error : unable to load R code in package 'ggplot2'
ERROR: lazy loading failed for package 'ggplot2'
* removing 'C:/.../R/win-library/3.5/ggplot2'
* restoring previous 'C:/.../R/win-library/3.5/ggplot2'
and

Any ideas on what I should look at would be great. Thanks, Jonny
