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??
