Hi ,

have a
looked on the help files and it says simple .... but when i go to cran
through load.packages() it does not come up ?
Under the heading of "Teach a man to fish, and he will not go hungry..."
Learn to use:
?help.search
# and
http://search.r-project.org/nmz.html
2. whenever I use qq.plot through library(car) it mentions i need a
graphics device ? perhaps you could me there as i loaded a graphics
device
and got an error ., I loaded cairo and cairo device and bot would not
install ? im not to sure why ?
Graphics devices are among the most OS-specific components of R. You
have not followed the Posting Guide's advice to include such
information. On my machine a graphics device gets loaded by default
when I issue a plot command, but it's possible that may not be true on
all systems.
?device
perhaps you need to issue dev.new() .... just a guess.
> dev.cur()
null device

library(car)
x<-rchisq(100, df=2); qq.plot(x) # draws the plot
