Hello!
I'm thinking of applying a censored regression model to
cross-sectional data, using either the tobit (package survival) or the
censReg function (package censReg). The dependent variable is left and
right-censored.
My hopefully not too silly question is this: I understand that

Hi,
I have two tables and I need to merge both. I use the merge command, but
in this way the name must be exactly. How I can make to compare
independently of upper or lower-case?
Look:
data1<-data.frame(journal=c("Ecology","Environmental
Entomology","Neotropical Biology And Conservation"))

Dear Xiang Gao,
See the OBrienKaiser example in ?Anova in the car package.
I hope this helps,

Hi,
you compute the same results for logx many times. So it is easier and
time saving tabulating all intermediate results.
smth. like
n<-10
CT=6000#assignment to CT
NT=29535210#assignment to NT
i <- 0:(n-1)
lookup<- lchoose(NT-n, CT-i) + lchoose(n, i)
lgmax<-cummax(lookup)

Dear all,
I have been using the lrm function in R to run an ordinal logistic
regression and I am a bit confused about the methods for checking the
model assumptions.
I have produced residual plots in R of the score.binary type which I
think look ok. However, the partial type plots show be
I have recently been using R - more speciifcally the GUI packages Rattle
and Rcmdr.
I like these products a lot and want to use them for some projects - the
problem
that I run into is when I start to try and run large datasets through them.
The
data sets are 10-15 million in record quantity

Installing Rtools is not hard, and doesn't have to happen often; the
hardest bit in Windows is making sure that the requisite executables are
on the path, and that j
Dear Dr. Wolf:
I understand your concern that the mechanics of writing an R

I came to embrace it, because I actually got more done in less

Dear Ann,
The easiest way is to seperate both plots into two subplots. And then use
viewport to paste them together.
Best regards,

There are simpler ways of maintaining R source code than building
packages. I bashed out a quick way of keeping code in directo

Dear all,
I'd like to know how I could compute the parameters "yaxp" and (the y
components of) "usr" without having to plot the data first. Note that
"ylim" is /a priori/ fixed.
The aim is to automatically adjust the parameter "mgp" without having to
make the plot twice. Then, with "yaxp" an
