Simple.lm

To find simple.lm, I suggest you look in the package
UsingR
You may need to load the package; it is not installed by default when you load R on your computer.

I regret that I can not help you with your second question.

Hi ,

I am struggling with two problems :

1. simple.lm - where do i find the package that installs that ... i 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 ?

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 ?

any help would be appreciated.

Regards

Malcolm

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
           1
 > plot(1,1)  # draws the plot
 > dev.cur()
quartz
      2

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