Hi. I am a newbie to R. I need to do a courses projects with some manipulation lots of data record and some back-and-forth linear regression. I do not want to spend $100 for a SAS lincence, which professor used. So I decide to start to learn R to finish it. I am using R in Windows. I feel it is somehow works like mathemica. I try to write the work into a little program for future reference.

I have two data sets about lots of companies' stock and fiscal data. One is monthly data with about 144,000 lines, and the other is quaterly with about 56,000. Each data set takes different company code. I need to merge these two together. I read both ask cvs. And the other file with corresponding firm code. Now I have three data sets. return$PERMNO, account$GVKEY. id is the data frames

I need to run a regression with 14 normal variables and 20 dummy variables. All the data is in a huge data.frame df. But there is some extra intermediate item in the same data.frame too. It will be nice I can strip off those terms and run lm(). Also, is there a simple way to write the formula, for example, just specify the y term, all other term in data.frame should be x_i. Or is there some

Dear R users, I want to share my joy with you. Please see the following excellent introduction to R "Statistiques avec R " by Vincent Zoonekynd http://zoonek2.free.fr/UNIX/48_R/all.html In paticular, you can see a lot of fascinating graphics examples of R from which you can get many hints. Soryy if this is already well-known, but the CRAN search did not show nothing with the keyword

I guess this is really basic. But I do not find an answer yet. I have a big data.frame. I would like to divede them into 10 deciles accounding to one of its member. Then I need a number for each decile with some computaion within each group. How to devide it?

Dears friends, I have been translating and extended, with educational porposes only, the available material in the www (http://zoonek2.free.fr/UNIX/48_R/all.html) "Statistcs avec R" for the Portuguese of Brazil.

My question is based on an example provided in the following: Referencing: Statistics with R Vincent Zoonekynd <zoonek at math.jussieu.fr> 6th January 2007 URL: http://zoonek2.free.fr/UNIX/48_R/all.html data(HairEyeColor) a <- as.table( apply(HairEyeColor, c(1,2), sum) ) # Provided Example barplot(a, beside = TRUE, legend.text = attr(a, "dimnames")$Hair) # I

Stock returns and other financial data have often found to be heavy-tailed. Even Cauchy distributions (without even a first absolute moment) have been entertained as models. Your qq function subtracts numbers on the scale of a normal (0,1) distribution from the input data. When the input data are scaled so that they are insignificant compared to 1, say, then you get essentially the

The following code was adapted from an example Vincent Zoonekynd gave on his web site http://zoonek2.free.fr/UNIX/48_R/03.html: n <- 1000 x <- rnorm(n) qqnorm(x) qqline(x, col="red") op <- par(fig=c(.02,.5,.5,.98), new=TRUE) hist(x, probability=T, col="light blue", xlab="", ylab="", main="", axes=F) lines(density(x),

Searched my R reference docs*, and the Rseek, but evidently I've overlooked this capabilty.    Is it possible to produce a 3d Barplot using R?   For example would like to have a three axis bar plot - \ x-axis = location(discrete), y-axis = data value, z-axis = frequency of value occurance (of location and value)   Would also if could also do something like what "qplot" allows,

When you set up phpBB, the admin can specify defaults. They include "Make email address private" and "Allow members to receive private messages" The admin would set they defaults to "yes" and "no" respectively.

About six months ago there was a reference to a site (in french) that did a spectacular job of demonstrating R's graphical capabilities. My bookmarks were recently wiped and I cannot find this site despite my best googling. Anyone have the address which I have done a miserable job describing? Thanks. Michaell
