Dear Michael,
Try ggplot2. Use something like
install.packages("ggplot2")
library(ggplot2)
recov <- 0:2
n <- 1000
all <- data.frame(bbED = rnorm(3 * n, mean = recov), recov =
factor(rep(recov, n)))
ggplot(data = all, aes(x = bbED)) + geom_histogram() + facet_grid(. ~
recov)
ggplot(data = all, aes(x = bbED)) + geom_histogram() + facet_grid(recov
~ .)
ggplot(data = all, aes(x = bbED, colour = recov)) + geom_density()
You'll find more information on ggplot2 at http://had.co.nz/ggplot2/
HTH,
Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

Onderwerp: [R] Multiple hist(ograms) - One plot
Hello,
I am trying to plot multiple histograms with the same scales, etc into
one
plot. The commands below produce a 3 page PDF with each histogram
occupying
the upper right quadrant. And use slightly different scales on the X and
Y
axes.
> s21 <- dat[dat$sc_recov=="21",]
> s21.ED <- subset(s21, select=(bbED))
> s31 <- all[all$sc_recov=="31",]
> s31.ED <- subset(s31, select=(bbED))
> s41 <- all[all$sc_recov=="41",]
> s41.ED <- subset(s41, select=(bbED))
> pdf("234_1_ED.pdf")
> par(mfrow = c(2, 2), oma = c(0, 0, 2, 0))
> hist(s21.ED) + hist(s31.ED) + hist(s41.ED)
> dev.off()
Also, for example if I add something like col="x", or main="x" to the
hist(x, ...) nothing appears on the plot. ?
Please advise,
Thank you kindly,
M Just
