I am trying to install some packages but I get these errors.
in addition: Warning message:
package ‘dplyr’ was built under R version 3.3.3
Error: package or namespace load failed for ‘dplyr’
for installing some packages I need to have an older version of R (version under 3.3.0)
so now I want to know how to find the old version of R and Rstudio. I try to download some versions but they don't work correctly.
if I want to install Rstudio version 3.0.0, how can I find its download link?
