another question on shapefiles and geom_point in ggplot2
Manuel:
I changed your variable names from x to 'long' and y to 'lat' on the
riqueza_out.csv file.
The code below should do what you want. Also, since the legend title is kind of
long, I broke it
down into three lines so you can see more plot area. I am cc'ing the other
groups so more people
use it if needed.

colnames(RT) = c('repetition','alternation')
rownames(RT) = c('7-yrs','11-yrs','15-yrs','21-yrs')

I have 5 years of weekly passage data and want to predict fish passage
for the following year. I don't have a model to use to predict data for

I just want to see on the graph what the predicted year would look like
and how those?new values are generated. Gracias?

I am using Sweave and texi2dvi to generate a LaTeX document but
