Re: ggplot2 with both stat_binhex and scale_x_log10

[Dennis Murphy]

I don't think anyone is in a position to help you without a
reproducible example. The obvious question is: what is the range of
matchlist and mismatchlist? One way to check, I guess, would be to do
the following:

g <- ggplot(unfilttable, aes(x=matchlist, y=mismatchlist)) +
stat_binhex(bins = 20)

# does any hexbin have an edge that drops below zero
# in either direction?
g

If so, you're going to get an error when trying to use a log scale in
that direction. If that's not the problem, we'll probably need a
reproducible example to uncover the problem.
