[R] Histogram with two colors depending on condition
Dear List, Say, we generate data like this- dat-rnorm(1000,1,2) hist(dat) How do i make the histogram, say, red (col = 2) before X = dat = 0, and rest say, green (col = 3) beyond X = dat = 0 in R? The resulting histogram could be like this http://ehsan.karim.googlepages.com/histogram.JPG (edited) Thanks in advance.

Re: [R] Histogram with two colors depending on condition
Here is something that is close: x - rnorm(1) y - hist(x, plot=FALSE) plot(y, col=ifelse(y$mid0,'red','green')) On Thu, Jul 17, 2008 at 5:13 AM, Mohammad Ehsanul Karim [EMAIL PROTECTED] wrote: Dear List, Say, we generate data like this- dat-rnorm(1000,1,2) hist(dat) How do i make the histogram, say, red (col = 2) before X = dat = 0, and rest say, green (col = 3) beyond X = dat = 0 in R?

Re: [R] Histogram with two colors depending on condition
Here are a couple of ways:
dat-rnorm(1000,1,2)
hist(dat, col='red')
tmp - par('usr')
clip(0,tmp[2],tmp[3],tmp[4])
hist(dat, col='green', add=TRUE)
# or
library(TeachingDemos)
hist(dat, col='red')
clipplot( hist(dat, col='green', add=TRUE), c(0, par('usr')[2]) )
Hope this helps,

Dear List,
Say, we generate data like this-
dat-rnorm(1000,1,2)
hist(dat)
How do i make the histogram, say, red (col = 2) before X =
dat = 0, and rest say, green (col = 3) beyond X = dat = 0 in R?
The resulting histogram could be like this
