Hi everyone,
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:
R.r['set.seed(42)']
p1 = R.r['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
