help with R
Folks, Two simple questions : (1) I have a data set (call it data.xls) in a folder in my hard drive. How do I perform a simple regression between two variables from that data set? After I click on 'R', what exactly do I type in? (2) Where do I get to see the complete library of packages offered by R? In particular, I am interested in quantile regression and logistic regression.

data -> data matrix that can be used in regressions
Dear R users, I have spent most of this day figuring out how to read STATA data into R (which eventually worked) and to run a simple OLS regression. It seems that the manuals are written in the most general and abstract way which does not really make it easy to understand what's going on.

online tutorials
I work for a Investment group with a very extensive training program and we are having our new hires take a statistics course at University of Chicago where they have to complete some assignments with R. I was wondering if there are any online tutorials that exist where we could get our participants comfortable with R before the class itself? I appreciate any help at all. Thanks, Matt Maxon

Simple rep() question duplicating times and dates.
I want to create a data.frame of time and date for a year. I started with the idea of simply producing two vectors (time and date) The first part ( time) is easy. rep(1:24, 365) But how do I get a series of 24 dates for O1 January 2005 and repeat this to 31 December 2005. It should be easy but I don't see it. Thanks

I have done several glm models with family=quasipoisson: model <-glm(Y~X+Q+Z,family=quasipoisson) and then used results.effects <-effect("X",model,se=TRUE) to get the "adjusted means". I am aware about the debate concerning adjusted means, but you guys just have to trust me - it

An "R is slow"-article
Hi all, Reading the wikipedia page on R, I stumbled across the following: http://fluff.info/blog/arch/00000172.htm It does seem interesting that the C execution is that much slower from R than from a native C program. Could any of the more technically knowledgeable people explain why this is so? The author also have some thought-provoking opinions on R being no-good and that you should write
