When plotting a numerical vector against a factor, 'type="n"' seems to have no affect, e.g. > plot (1:10~factor (1:10), type = "n")
looks just like > plot (1:10~factor (1:10)) Plotting a numerical against itself works as expected: > plot (1:10, type = "n") I see the same behavior under debian gnu/linux, Mac OS X, and Win7 (all current versions, see below). Is this a bug?
