Dear All,
Please see the code snippet at the end of the email.
I am using the color2D.matplot in Plotrix to plot a matrix.
It works great, but there are a few things I cannot figure out
(1) the value of cex.axis in the code snippet does not seem to affect
the final pdf at all (at least on my system, Ubuntu 9.10, plotrix and
Cairo installed from cran). How do I specify the size of the axis ticks
and the corresponding numbers?
(2) Can I specify the number of decimal figures in the max/min value in
the legend?
(3) Can I replace the numbers along the x-axis with e.g.
c('a','b','c','d','e')?
(4) Do I need to resort to color.legend if e.g. I want to rotate the
legend and align it to the y axis?
Many thanks
Lorenzo
