Hello,
That is a unix/linux command and you are on Windows. The cat command and
other unix/linux commands can be installed when you install Rtools [1].
It is not well seen to cross post [2].

I installed the "XLConnect" package which appears to be successful and then tried to load the
"XLConnect" library and got an error as shown below. Any ideas as to where to look for the source of the
error? The word "release" in the error message makes me think it is some issue with the version of
"XLConnect" but that is just a guess.
I am running the latest version of R available on CRAN on Windows 10.
install.packages("XLConnect")
Installing package into ‘E:/Data/OneDrive/Documents/R/win-library/4.0’
(as ‘lib’ is unspecified)
trying URL
'https://cran.rstudio.com/bin/windows/contrib/4.0/XLConnect_1.0.3.zip'
Content type 'application/zip' length 29498979 bytes (28.1 MB)
downloaded 28.1 MB
package ‘XLConnect’ successfully unpacked and MD5 sums checked
The downloaded binary packages are in
C:\Users\User\AppData\Local\Temp\RtmpARt8Er\downloaded_packages
library(XLConnect)
Error: package or namespace load failed for ‘XLConnect’:
.onLoad failed in loadNamespace() for 'XLConnect', details:
