Hi everyone,
Sorry for the double mail, I accidentaly pushed a button that send it off
before I was finished.
I'm trying to rebuild a R example in rpy2 given in this thread in
stackoverflow:
http://stackoverflow.com/questions/3541713/how-to-plot-two-histograms-together-in-r.
The example looks like this:
set.seed(42)
p1 <- hist(rnorm(500,4)) # centered at 4
p2 <- hist(rnorm(500,6)) # centered at 6
plot( p1, col=rgb(0,0,1,1/4), xlim=c(0,10)) # first histogram
plot( p2, col=rgb(1,0,0,1/4), xlim=c(0,10), add=T) # second
This creates two histograms in one plot, with one histogram being blue, the
other being pink and the overlap being purple. You can paste and run this
in R to see the result.
So I made the following in rpy2:
import rpy2.robjects as R
r = R.r
r['set.seed(42)']
p1 = r['hist'](r['rnorm'](500,4)) # centered at 4
p2 = r['hist'](r['rnorm'](500,6)) # centered at 6
r['plot']( p1, col=r['rgb'](0,0,1,1/4),
xlim=R.vectors.IntVector([0,10])) # first histogram
r['plot']( p2, col=r['rgb'](1,0,0,1/4),
xlim=R.vectors.IntVector([0,10]), add=True) # second
This gives the same overlapping histogram plot, except that histograms are
nog coloured. How can I color the histograms?
Thanks,
Niek
