I`m keen to install the latest version of the R XML package on Windows

I`m keen to install the latest version of the R XML package on Windows which is not on CRAN

From other stackflow questions I have downloaded the relevant zip file XML_3.9-4.1.zip
but need some step by step help

I have tried running

install.packages("C:\Users\pssguy\Downloads\XML_3.9-4.1.zip", repos = NULL, type="source")`

and get error 

Error: '\U' used without hex digits in character string starting "C:\U"

Should I be unpacking the zip first?

There also seems to be a command mode option. Is that better and if so, what directory should I be in before and what would be exact code

TIA

    \ is used to denote that you want to escape the following character in strings. Replace all of the \ in the path to the file with either \ or /

    So change "C:\Users\pssguy\Downloads\XML_3.9-4.1.zip" to "C:\\Users\\pssguy\\Downloads\\XML_3.9-4.1.zip" or "C:/Users/pssguy/Downloads/XML_3.9-4.1.zip"
