问题
Currently, I'm using R version 3.4.4. And I'm trying to use R package 'effects'. But I can't install & use this package on this version.
code
install.packages("effects")
library(effects)
plot(allEffects(lm_g_sc), type="response")
results
Warning in install.packages : package ‘effects’ is not available (for R version 3.4.4)
What can I do? If I can't use this package, there are some alternative packages?
回答1:
As a result of a related Stack Overflow question, I built a package specifically for this purpose, oldr. The package is available here:
https://github.com/duckmayr/oldr
You can install via
devtools::install_github("duckmayr/oldr")
Once the package is installed, you just need to run
oldr::install.compatible.packages("effects")
The function oldr::install.compatible.packages() searches through the CRAN archives to find the newest version of the package that is compatible with your installed version of R.
