Thanks, running r44621 works well (on my FC5 box) and I can make various plots (I just did some limited testing).
When I run the 'TestChars()' example in 'points' I get many warnings of the form: 1: In plot.xy(xy.coords(x, y), type = type, ...) : pch value '128' is invalid in this locale 2: In plot.xy(xy.coords(x, y), type = type, ...) : pch value '129' is invalid in this locale 3: In plot.xy(xy.coords(x, y), type = type, ...) : pch value '130' is invalid in this locale The warnings go until 49: In plot.xy(xy.coords(x, y), type = type, ...) : pch value '176' is invalid in this locale 50: In plot.xy(xy.coords(x, y), type = type, ...) : pch value '177' is invalid in this locale after which I think the warnings are not saved. Given the note in 'points' I sense this is expected? TestChars(sign = -1) and TestChars(font = 5) do not give any warnings but some odd looking characters do appear on the device.
