install problem

Package development

HI, nice to join this community. I have just started to run R. I wonder whether you can give any answer to the message below from R:
I tried to install Java and apply any method which I got from this community.

install.packages("xlsx")
trying URL 'http://cran.rstudio.com/bin/macosx/big-sur-x86_64/contrib/4.4/xlsx_0.6.5.tgz'
Content type 'application/x-gzip' length 374751 bytes (365 KB)

downloaded 365 KB

The downloaded binary packages are in
/var/folders/t_/2bbtr1912qq_bbhh9j6crj900000gn/T//Rtmp3f2ts1/downloaded_packages

It seems to mean that {xlsx} has been successfully installed and you are good to go. This is just where the files used to install the package have been stored, I "think" it is just a temp file.

In Ubuntu Linux I get a similar message


The downloaded source packages are in
	‘/tmp/RtmpIL75r6/downloaded_packages’

When I quit R the temp folder is deleted.
