In a histogram , is it possible to have different colors?
Example. I generated
x <- rnorm(1000000)
hist(x)
I want the histogram to have different colors based on the following
condition
mean(x)+sd(x) with red color and mean(x) - sd(x) with red color as
well. The middle one with blue color.
bkrs <- hist(x); hist(x, col= ifelse(bkrs$mids< 0-1,"red", ifelse(bkrs
$mids> 0+1, "blue", "black" ) ) )
This has the side effect of first plotting a "histogram" with bars
that have default fill but then gathers the values in an object bkrs
that is used to assign colors based on midpoints. Following your lead,
I used the default values for mean and SD, so filling them in is left
as an an exercise for the poster.
Is it possible to do that in R?
Thanks
