TeX was unable to calculate metrics for the following string or character: m

ThomasWilli commented 4 years ago

While I had tikzDevice working nicely, it no longer wants to work for me. When dealing with a simple plot as shown below it gives the above error. I updated all my packages (from dev as suggested here #114) but without success. I used a second machine and got the same error.

library(tikzDevice)
tikzDevice::tikz("test.tex", width = 3.5, height = 3)
plot(1:10)
dev.off()

Measuring dimensions of: m
Running command: '/usr/local/bin/pdflatex' -interaction=batchmode -halt-on-error -output-directory '/var/folders/_m/jtfsgy79743fd5wlqhjkjhjm0000gn/T//Rtmp5IHDhh/tikzDevice388f4b8f810e' 'tikzStringWidthCalc.tex'
Error in getMetricsFromLatex(TeXMetrics, verbose = verbose) : 
TeX was unable to calculate metrics for:

m

Run the following commands for diagnosis:

tikzTest()
tikzTest("m")

Common reasons for failure include:
  * The string contains a character which is special to LaTeX unless
escaped properly, such as % or $.
  * The string makes use of LaTeX commands provided by a package and
the tikzDevice was not told to load the package.

The TeX and log files used for the calculation can help diagnose the
problem. If these files are missing, rerun the plot and make sure to
keep the R session open.
TeX file: tikzStringWidthCalc.tex
Log file: tikzStringWidthCalc.log

When I run tikzTest("m") it tells me that

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

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

Enter file name: 
! Emergency stop.
