Dear Jeffrey
You found a bug in the variogram plotting procedure. Yes, 'cex' should behave like your description.
Fixing this bug will need to deliver a new release of RGeostats. I'm afraid it won't be in the near future.
As a workaround, I suggest you to hide the variogram legend (using pos.legend=0 in plot(vario) ) and plot the legend by hand using :
- Code: Select all
legend.vario(vario,ndir=1,flag.point=TRUE,flag.line=TRUE,position=legend.locate(1),cex=3)
Here, you will be able to resize the legend text using 'cex'.
Best regards
