Paul, Subassignment for units has been committed to r-devel. You should now be able to do things like ...
x <- unit(1:3, "mm") x[2] <- unit(.5, "npc") (see grid/tests/units.R for more complex examples) Yes, I just tried the latest R devel and it works for me. However: This works for me for the three stackoverflow scenarios. I ran into an additional problem when trying to replicate this example: http://stackoverflow.com/a/32583612/4975218 This line in the function set_panel_size() causes an error for me: g$widths[panel_index_w] <- rep(list(width), nw) Error in `[<-.unit`(`*tmp*`, panel_index_w, value = list(4, 4, 4)) : Value being assigned must be a unit I can avoid the error by changing the line into: g$widths[panel_index_w] <- rep(grid:::unit.list(width), nw) This, however, again uses grid:::unit.list(). Maybe there’s another way around this, but turning a single width value into a unit.list seems the obvious way to go in a case like this. So again, I’d like to request that grid:::unit.list() be made an exported function as well. It seems quite useful any time somebody wants to make a list of units. Thanks!
