- R version is greater than or equal to
- The matching version of R tools is installed;

Two things you might want to check.
First, whether you have installed the correct version of Rtools that matches your
Every time you open
R, you will see your
R version information. Alternatively, you can check your
R version by running the following command in an
> sessionInfo() R version 3.2.2 (2015-08-14) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 7 x64 (build 7601) Service Pack 1 locale:  LC_COLLATE=English_United States.1252 LC_CTYPE=English_United States.1252 LC_MONETARY=English_United States.1252 LC_NUMERIC=C  LC_TIME=English_United States.1252 attached base packages:  stats graphics grDevices utils datasets methods base loaded via a namespace (and not attached):  tools_3.2.2
For example, here I’m having
3.2.2. However, the minimum
R version requirement is
3.3.0. Therefore, I decided to update to the current latest
3.5.1. To update to a newer version, it is a good practice to manually delete the older version. For my case, my older
R is at the default location,
C:\Program Files\R\R-3.2.2. I executed the program
unins000.exe in the folder to uninstall the older version. Then I can safely install the newer version without worrying about having multiple versions of R installed.
However, it looks like
RStudio does not automatically detect the updated version of
R. You can inspect which
RStudio using by typing the following command in an R session:
> .libPaths()  "C:/Users/student/Documents/R/R-3.2.2/library"
Looks like in my case
RStudio is still using another
R that is installed in a non-conventional place. I went ahead and delete that R by running the uninstall program. Then when I reopen
RStudio, it automatically finds the latest R that I’ve installed earlier.
If you check the Rtools table, I should be installing
Rtools35.exe for compatibility reasons. Please install the matching version
Rtools for your
R and choose to add it to your
PATH during the installation. I’ll come back to this afterwards and this is very convenient and helpful. The above should resolve part of the problem.
Second, whether you have chosen to add the
Rtools path to your system
PATH when you were installing
Rtools, and whether you have restarted your Windows in order for
PATH modification to have effect.
Rtools to your system
PATH variable enables the system to find tools during execution. To check whether you have added the
Rtools path to your system environment variable
PATH, you need to open up the system environment variable dialogue (Google it if you don’t know how to find it. It should be straightforward.). Your
Path should contains something like below:
Finally, restart a R session and try installing the package again. If problems remains, please open a ticket.
