ggplot2: labels and breaks order does not match and I can't use scale_fill_identity
Hi,
I'm plotting a bar chart like this:
ggplot() +
geom_bar(data=res,aes(fill=f1,x=f2,y=y),stat="identity",position="dodge")
f1 contains quite a few levels and the plot is really quite difficult to
read when the order of bars on the graph and on the legend does not match.
This problem has been discussed recently here:

Another loop avoidance question.
...matrix(0,nrow=n,ncol=k2)
pt1 = proc.time(for (i in 1:k1) output1 = output1 + m1[,i]*m2)
## Approach 2: loop on k2
output2 = matrix(0,nrow=n,ncol=k2)
pt2 = proc.time(for (i in 1:k2) output2[,i] = rowSums( m1*m2[,i] ))
## Same result
sum(output1-output2)

ggplo2: x_discrete labels size/direction
Hi everyone,
I've got quite a few labels along the x axis and ggplot2 basically just
crams them on top of each other.
Is it possible to reduce the font size and/or text direction?
Stretching the "windows" device window manually also helps, but I found that
setting the parameters for the pdf device (where my scripts should print the
data), such as paper="a4r" just results

writing polygons/segments to shapefiles (.shp) or other A rcGIS compatible file
The main limitation of the shapefiles package that I put together is that it
does not create shapefiles from R objects - rather it only writes shapefiles
that have been read into R and manipulated within the constraints of the
existing file structure. By this I mean that for example you can change the
coordinates of points and write them back out. Or you can add a bunch of
blank columns in the
