Could anybody please help.
I have a simple linear regression model with 5 predictors. I want to

Hello,
as far as I see, R reports type I sums of squares. I'd like to get R to

I've encountered some of the same issues with jaggy graphics. Here
is what I have found to work pretty well:
Short and sweet:
Use the bitmap() function with res=200 to create png files.
Some explaination:
As far as I can tell, png(), jpg(), and friends do not allow you to
set the resolution.
You may try something like this:
postscript(file="fig.ps",height=4,width=4)
layout(matrix(c(0,1,2,0,3,4),2,3,byrow=TRUE),c(0,1,1),c(1,1))
par(mar=c(5,5,2,2)+.1,mex=.6)
The default spacings are different for 2x3 and 2x2. The layout
facility allows one to cheat it out.
Good luck.

The simplest way is to define the method correctly, as print.myclass(x,
myarg, ...). That message is about the code, not the documentation, but
you will get a different one if the code and documentation disagree.

Dear R Gang,
I'm interested in using R and the nls package for fitting kinetic
models. I'm having some difficulty getting a model specified for
nls though. The math for the model that I want to fit is
dg(t)/dt = K1 f(t) - k2 g(t)
where g(t) and f(t) are measured data at a sequence of times
After trying numerous options, I'm just about at my wits end.
The most frequent suggestion was to export to a postscript or PDF file
and import that into Word.
However, no matter what I did or how I did it, the results were
extraordinarily ugly and somewhat time-consuming.

Regarding "1", both "cat(x)" and "print(x)" have worked for me,

Hope this helps.
