Can anyone interpret this for me?

I fail to install xfun (and at times other packages) and I cannot interpret these messages. In addition, it says that xfun needs compilation == TRUE.

 There is a binary version available but the source version is later:

You seem to be running an old version of R. If you update to the most recent version, you will probably have fewer problems installing packages.

You are missing the RTools compiler for 32-bit systems, you can download RTools for your R version from here

R for Windows Build Tools Archive

But, as FJCC says, it would be better if you update your R version, precompiled binary packages are only available for the latest R versions.
