Re: [Rd] Converting width for a grob where graphics parameters have length 0 crashes R

2021-11-15 Thread Paul Murrell 

Hi

There is now a fix for this problem in r-devel (r81197).

Thanks for reporting the problem!

Thanks for bringing this (back) up.

It is still on my list, but now back nearer the top :)

Dear developers,


In grid::gpar(), graphic parameters are not allowed to have length 0, 
but this can be done by first creating a gpar object and later 
modifying it:



gp = gpar(fontsize = 10)

gp$fontsize = numeric(0)


when a grob has a gp where some parameters have length 0, converting 
the width or height of this grob will crash R.


?

A reproducible example is as follows:


 > library(grid)

 > gp = gpar(fontsize = 10)
 > gp$fontsize = numeric(0)
 > gb = textGrob("foo", gp = gp)
 > convertWidth(grobWidth(gb), "mm")
[1] 21045 floating point exception R??
