I'm using R4.3.1,and I manually installed a package 'estimate' from here. I have installed corresponding Rtools. However, when I try to library this package, there is a problem:
Error: package or namespace load failed for ‘estimate’:
package ‘estimate’ was installed before R 4.0.0: please re-install it
Then I try to do the following, but the problem persists when I library it:
update.packages(ask = FALSE, checkBuilt = TRUE)
P.S. I have re-installed it and any of other packages, but the same problem still exists
What is happening and what should I do?
