I want to change the colour of the histogram in each panel by the
levels of
the conoditonal factor.
I have 3 levels in the factor
levels(data[,2])[1]
levels(data[,2])[2]
levels(data[,2])[3]
what can i do , in order to chnage the colour ??
Why do you suppose there is a FAQ?
Assuming that the underlying levels are coercible to numeric type then:
col = as.numeric(as.character(data[ , 2] ) )
and of course:
library(fortunes)
fortune("dog")

Fore example my code is
histogram(~data[,8]|data[,2], ylab = "Frequency", xlab = "Score",
xlim =
c(1,5), ylim = c(0,100),layout = c(3,1),col=data[,2] )
and i want the colour to be depended on the level of the factor in
data[,2]. how do i do that ?
