Subject: [R] histogram-like plot - multiple bars side by side

Hi,

I found this example for producing multiple histograms;

  require(plotrix)
  l <- list(rnorm(50),rnorm(50,sd=2),rnorm(50,mean=3))
  multhist(l)


Now I want something like that, for creating multiple density
distributions (in one plot).

But I have two variables for one density distribution and "multhist"
only allows me to add one variable;
   x <- seq(from=0, to=14, by=1)
   y <- dbinom(x, 14, 0.7, log = FALSE)


Is there a way to make a histogram-like plot with multiple bars side
by side (for different distributions) like in the example?

Do you mean something like this:

x <- 0:14
y1 <- dbinom(x,14,0.7)
y2 <- dbinom(x,14,0.5)
y3 <- dbinom(x,14,0.3)

barplot( rbind(y1,y2,y3), names=x, beside=TRUE)

Hope this helps,
