Description
Apparently, ggplot2
relies on sf
to draw the graticule and axes labels. Currently, when trying to plot to tikzDevice
the usage of plotmath expression for the degree symbol in the axes labels paste0(abs(x), "*degree", dir[pos])
(see degreeLabelsEW
function) leads to an error as ‹there is specifically no support for input of plotmath characters as unicode since the user can simply input Latex math directly› (Tikz User Manual).
I wanted to suggest to hard code the degree symbol as \u00B0
which is rendered correctly with the default graphic device but also with tikzDevice using the options(tikzDefaultEngine = 'xetex')
.
