interpretation of lm
Dear statistitians / R users,
I was told to analyse the effects of the four factors
using lm or update for aov. The following is the
result from lm. As you can see that in the last few
lines enclosed coefficients.
1)Does this mean I can write a formula, like
yield =0.26 + 0.03*H + 1.48*T + 0.04*L + 0.004*C

comparing predicted sequence A'(t) to observed sequence A(t)
Hi,
I have a question that I have not been succesful in finding a definitive
answer to; and I was hoping someone here could give me some pointers to
the right place in the literature.
A. We have 4 sets of data, A(t), B(t), C(t), and D(t). Each of these
consists of a series of counts obtained in sequential time-intervals: so
for example, A(t) would be something like:
Count A(t): 25,

...ether drug treatment has an effect on
exploration plus the combined effect. Checking out the mailing list
archives I found the helpful page by J. Baron on R in psychology and
tried to adapt his example in chapter 6. Below you can find the
result, and I simply wanted to ask some more experienced statistitian
than me if I did the right thing with these data.
Thanks in advance, Christian.

2 questions
Hi all,
I am using R1.5.0 under Unix,
I have a couple of questions here.
1. My program is running out of memory. I am writing a program to grow a
list of trees using rpart() on a subset of a large dataset(5807x693) with
a different response for every tree. I saw that after each tree was
constucted, 116 MB of data was being added to the Vcells. I have no idea
what this data is. My dataset is
