R help - Nov 2009 - Output

Hi all,

I fitted a model  say with five

xc<-lm(  y~x1,x2,x3,x4,x5)

I want to plot the residuals for each factor and I used this,

plot(xc,residuals=TRUE,se=TRUE,pch=".")

I only get the plot of the last factor (i.e., x5). I think it is
overwriting.

How can I send  the five plots into  a file?  I usually use cut and paste
and this may not be the right thing to do.

Thanks in advance

Hi,

I use two ways to solve this..

1- Assuming you are runing R under Windows platform you could use
>windows(record=T)
>plot(xc,residuals=TRUE,se=TRUE,pch=".")
That way the graphic window will "save" all five outputs and you can
surf
them via "PageUp", "PageDown" keys...

2- See ?jpeg to export the graphics in image format, but for me it's easier
(cleaner) to export them to pdf like this:
>pdf(file=("your_file.pdf"),onefile=T)
>plot(xc,residuals=TRUE,se=TRUE,pch=".")
>dev.off()
This is a very simple matter, I encourage you to look for FAQ's and manuals
before posting

Greetings
