older version of R and Rstudio

hello everybody
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?

This is happening because the R version you are using is too old for dplyr

Can you give an example? Using such an old version of R doesn't sound like a good idea, maybe if you give more details about what package you are trying to install and for what purpose, someone might be able to give you an alternative solution.

You would need to travel to the future, since latest RStudio version is 1.4.1106... I'm kidding of course, I think you actually mean R version 3.0. You can find the source code for all versions here Index of /src/base but they require compilation.
