I get the following error out of R, on a newer Ubuntu installation.
Error in `axis()`:
! X11 font -adobe-helvetica-%s-%s-*-*-%d-*-*-*-*-*-*-*, face 1 at size 12 could
not be loaded
Backtrace:
1. graphics::matplot(...)
3. graphics::plot.default(...)
4. graphics (local) localAxis(...)
6. graphics:::Axis.default(...)
7. graphics::axis(side = side, at = at, labels = labels, ...)
The context is pretty simple:
library(survival)
matplot(60:100, 36525* survexp.us[61:101, 1:2, "2014"], col=2:1, lty=1, lwd=2,
xlab="Age", ylab="Death rate per 100", log='y', type='l', yaxt='n',
main="US Death Rates")
axis(2, c(1,2,5,10,20, 50), c(1,2,5,10, 20, 50), las=2)
This code works fine on my screen. The error comes up when I put it into an
.Rmd file
and apply rmarkdown::render() to it.
Likely some font file is needed, but what one?
