I had updated a few packages in R using the following command - 

install.packages(c("BH", "DBI", "Matrix", "SparseM", 
                   "broom", "caTools", "callr", "cli", 
                   "curl", "data.table", "digest", "e1071", 
                   "foreign", "htmlTable", "igraph", 
                   "maptools", "multcomp", "nlme", "openxlsx", 
                   "plyr", "quantreg", "rmarkdown", "survival", 
                   "testthat", "tinytex", "vctrs", "webshot"))

After this, every time I load tidyverse library (using library(tidyverse)), I get the following output. Is any of the updated packages causing this? I cannot find any similar problem / solution online. I have not had this problem before.

Appreciate any input. Thank you.

    Can you edit your post to show the output of `sessionInfo()` – Rohit Dec 18 '19 at 11:32
  • `U+2500` is the [Box Drawings Light Horizontal](https://www.compart.com/en/unicode/U+2500). When loading, package `tidyverse` displays a message with those characters, so maybe you should check your system's encoding. – Rui Barradas Dec 18 '19 at 11:42

    See this previous question... https://stackoverflow.com/questions/59379565/encoding-issue-in-tidyverse-startup-message-in-rstudio-distorted-utf-8-output – Andrew Gustar Dec 18 '19 at 11:46
  • @AndrewGustar Thank you for the link. I did more reading and it is a problem of the 'cli' package. The issue has been corrected in the master branch on GitHub. I tried `remotes::install_github("r-lib/cli")` to get it. It downloads fine, but has an error while installing. This is on a Mac (El Capitan). Any thoughts?Last two lines on error: building 'cli_2.0.0.9000.tar.gz' Error: (converted from warning) Setting LC_CTYPE failed, using "C" – sk1536 Dec 19 '19 at 09:07
