This is a new user of R.

TikzDevice and ggplot2 have been installed in R Studio on MacBook Air.

An error occurred when trying to run the blue code in the screenshot.

I tried to use tikzTest() to check the error. The error was ! LaTeX Error: File 'tikz.sty' not found. The full output of tikzTest() is after the screenshot.

Just wondering how to fix this error?

P.s. I've installed MacTex but could not find tikz.sty in packages or updates.

Much appreciated if some solutions could be provided.

    What exactly did you install in order to run LaTeX with RStudio. Sometimes we see it installing BasicTeX which is a minimalistic LaTeX installation, which I assume does not include tikz. – daleif May 14 at 12:58
  • Hi Daleif, I installed TinyTeX and TikzDevice in R studio. I also installed MacTex in a different location on the same laptop. – Water May 15 at 5:12

You have the TinyTeX¹ distribution which does not necessarily include everything. The documentation for TinyTeX offers this advice:

If you compile a LaTeX document and run into an error message like this:

! LaTeX Error: File `times.sty' not found.

Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: sty)

It basically indicates a missing LaTeX package. Do not panic.

It then suggests running tlmgr from a command line to identify the needed package:

tlmgr search --global --file "/tikz.sty"

(the / at the beginning of the file name is to make sure you don't get all the files that end with tikz.sty but rather just the one with that actual name). This will give you output that has the lines:


the pgf on the first line is the name of the package you need to install. You can now, at your command line, type:

tlmgr install pgf

Files will be downloaded and afterwards all should be well.

  1. Important note: MacTeX is a different installation than TinyTeX. MacTeX is a full TeX-live distribution which would include all the packages. It takes a while to download and a lot of space to install. TinyTeX is a subset of TeX-live which does not include all the packages and installs to a different location.
  • Thank you very much, Don. I tried tlmgr_search('/tikz.sty') and get tlmgr: package repository ctan.math.illinois.edu/systems/texlive/tlnet (not verified: gpg unavailable) pgf: texmf-dist/tex/latex/pgf/frontendlayer/tikz.sty Then, I tried tlmgr install pgf, but get Error: unexpected symbol in "tlmgr install" Not sure how to solve this issue. Much appreciated if some solutions are available. – Water May 15 at 5:07

  • It might also be the case that, if you installed tinytex more than a month or so ago, you're bumping into the annual texlive freeze. and you may need to update everything: try tlmgr update --self --all then tlmgr path add then fmtutil-sys --all – Don Hosek May 15 at 5:17
  • Thanks Don. The tex.stackexchange.com/a/578950/202780 works :) – Water May 15 at 7:07
