在 R Studio 上安装 R 包的问题

Question

I work on Rstudio and my version() result is:

> version
               _                           
platform       x86_64-w64-mingw32          
arch           x86_64                      
os             mingw32                     
system         x86_64, mingw32

language       R                           
version.string R version 3.3.1 (2016-06-21)
nickname       Bug in Your Hair

I downloaded the latest version this morning from the web to have the last update. On this, I can not install the package "raster":

> install.packages('raster')
WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

https://cran.rstudio.com/bin/windows/Rtools/
Installing package into ‘C:/Users/florent/Documents/R/win-library/3.3’
(as ‘lib’ is unspecified)
Warning in install.packages :
  package ‘raster’ is not available (for R version 3.3.1)

I have checked many help online but I can´t find the solution. I did an update of R (to 4.0.2) with which this raster package is working.

Anyone has a solution for this? It begins to be tricky...

Thanks!

It appears that you updated RStudio , but not R . RStudio is a program to make it easier to use R. So what you need to do is install the current version of R . As you can see from your version , you are using a version from 2016. That is ancient in the R world.

In RStudio you can look under Tools / Global Options / General / R version and perhaps change the R version if multiple versions are available.
