I'm desperately trying to install the package "effects" in RStudio, but it seems impossible.
What can I do?
See the warning message below:
Installing package into ‘/home/user/R/x86_64-pc-linux-gnu-library/3.4’
(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘effects’ is not available (for R version 3.4.1)
Thanks in advance,
