generate a series of fucntion
Hi there,
I want to generate a large amount of functions,
say f=function(x,t) exp(-t[1]-t[2]*g_1(x)-t[3]*g_2(1+x))
where g_1(x) and g_2(x) are from a long list of moments, such as x, x^2,
log(x), log(1+x) .. and so on.
Any suggestions on how to do this efficiently?
thanks a lot.

use expression() in a loop
Hi all,
I want to do plot() in a loop to make 10 graphs, so I have some code like
for (i in 1:10) {
plot(... ... , xlab = expression(g[i]) )
}
I expect g_1, g_2, and so on appear on x labels, but it simply prints
g_i for each graph. Does anybody know how to get around this problem?
Thanks.

Comparing Proportions Among Groups
Hi everyone,
I am trying to compare proportions among groups using the logistic
regression
approach as follows:
1) Fit the model log(p_i/(1-p_i)) = M + G_i, where p_i is the probability
of success in group i and G_i is the effect of group i, i=1,..,I.
2) Test the hypotheses:
Ho: G_1 = G_2 = ... = G_I (the probability of success is the same for all
groups)
versus
Ha: at least two G_i's are different (at least two groups have different
probabilities of success)
I am wondering if there any R functions available for accomplishing these
tasks.
Using dummy variables is one opti...

Differential Equations Using R?
To whom it may concern,
I am a student at Macaleste College, and next semester Macalester
is going to offer a course for CellBio that is mainly statistically based.
For the most part the students will be using R for analysis. The problem is
there will be some simple differential equations for the students to solve.

Rebuild of kernel 2.6.9-67.0.20.EL failure
Hello list.
I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without
modifications.
How did I try it?
Created a (non-root) build environment (not a mock )
Installed the kernel.scr.rpm and did a
rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee
prep-out.log
The build failed at the end:
