Changed the way fonts are imported into the R environment to insert fonts into the plot. For this method, the extrafont package was changed to the showtext package. (#48, #53)
The reason is that the extrafont package uses the Rttf2pt1 package, because Winston Chang, the author of the Rttf2pt1 package, says:
“ttf2pt1 has not been maintained since 2003, and it is getting increasingly difficult to make it compile without significant warnings on modern compilers, which in turn is making it difficult to maintain this package on CRAN. It is possible that in the future, I will not have time to keep this package on CRAN.”
