You can stop all of that output after the first mention of Timeout of 60 seconds was reached. It appears you are experiencing network glitches, and R is not adapting to them well.

Three suggestions:

  • increase R's timeout, per @Phil's answer;
  • keep trying with install.packages(..) until it finally works, hoping luck will eventually smile on you; or
  • download externally, verify the files downloaded, then install manually.

Assuming the third, then using firefox/chrome/safari (or whatever you prefer), download the URLs present in your R console manually to a directory. I'll assume the local directory, but you can save them to where-ever you prefer.

AP <- available.packages()
AP[AP[,1] %in% c("rmarkdown", "stringi"),c("Package", "Version", "MD5sum", "Repository")]
#           Package     Version MD5sum                             Repository                            
# rmarkdown "rmarkdown" "2.9"   "acd82da6a09f8e6564595dfa9039e032" "https://cran.rstudio.com/src/contrib"
# stringi   "stringi"   "1.7.3" "94c37221840cd9f5b7545c585d0c6b07" "https://cran.rstudio.com/src/contrib"

system("md5sum rmarkdown_2.9.tar.gz")
# acd82da6a09f8e6564595dfa9039e032 *rmarkdown_2.9.tar.gz
# [1] 0

(and repeat for stringi).

Assuming that the checksums match, then you can do

install.packages(c("rmarkdown_2.9.tar.gz", "stringi_1.7.3.tgz"), repos = NULL)

to install the downloaded files.

The error is that the timeout of 60 seconds is reached (i.e. it's taking too long to download). A workaround is to increase the timeout time:

options(timeout=120)

Or maybe longer if you need it
