I'd rescale my data to minimum around 0 and use some separate axis()
that takes the rescaling into account - given there is no package that
already does it. ;-)

Hi,
I have data that is on a log base 2 scale. It goes from negative factors of
2 to positive ones. I am using barplot. However, I don't want the data
centered at 0 - I want the min of the yaxis to be just below the lowest
value in the data. The plots are kind of deceptive switching between
positive and negative. I see that barplot has a log option, but that
doesn't seem to be adjustable for a log base 2 scale. Does anyone know how
to adjust the x-axis, so it's at y= -value rather than at y=0? I''d rather
not add a factor to the data, unless I can have accurate labels on the
y-axis.
Any ideas?
Thanks,
Summer
