similar to: R and S-Plus: Two programs separated by a common language?

Paul Just as in your implied analogy there are significant differences beneath the surface between these programs despite superficial similarities. You will soon get frustrated trying to use both simultaneously as you will not be sure that the critical step you've discovered in one will work in the other. Most basic functions will work but I suspect that you will soon discover some

Hello - I need to do simple linear autoregressive model with R software for my thesis. I looked into all your documentation and I am not able to find anything too helpful. Can someone help me with the codes? Thanks Emil [[alternative HTML version deleted]]

hi I've used R for many years on windows machines, but have now acquired an Asus eee 1000 linux machine. In order to get the best out of the machine, I used the 'pimpmyeee.sh' script, to get the full KDE desktop. The version of Linux is Xandros, which I believe is a close relative of Debian, but sadly I have only a nodding acquaintance with Linux at present. Naturally I want to

I am not new to R, but I am new to .grib files. I am downloading some climate data and I would like to analyze it in R. R has a nice netcdf package, but I don?t see any package available to deal specifically with grib files. I see a few posts from other people using grib files in R. However, I was unclear if they used grib files in a different software program and then imported the data

Hi I implemented the age-structure model in Gove et al (2002) in R, which is a nonlinear statistical model. However running the model in R was very slow. So Dave Fournier suggested to use the AD Model Builder Software package and helped me implement the model there. ADMB was incredibly fast in running the model: While running the model in R took 5-10 minutes, depending on the

What is the recommended way of requiring a certain version when loading a package (or, indeed, from R itself)? Perl has the require module version use module version require version use version constructs which is kind of what I am looking for (especially 'use' which is evaluated at compile time), but R seems to have lost the version= argument to require(). The best I have been able

I've gotten to the point wih an R script where I would like to encapsulate several blocks of codes in R functions. In order to keep the top level script simple I would like to put them in a separate file. This should help the readability of the top level main script. Is source(...) the best way to load those functions in the top level script? For example, in the top level script Line# 01

Dear R gurus... How do I control "smoothing" of a density plot in panel.densityplot when using histogram? Thanks much, Santosh [[alternative HTML version deleted]]

... Both readLines() and scan() produce a number_of_lines x 1 vector; trying paste(s, collapse = NULL) leaves it unaffected. How can I concatenate vector elements (lines) into a single string?

Given an arbitrary data frame, it is easy to exclude a column given its index: df[,-2]. How to do the same thing given the column name? A naive attempt df[,-"name"] did not work :)

HI, R-Users, I have one problem: I have written the the programs which process all file in one directory: for example: setwd("C:/Documents and Settings/lma/My Documents/Vappu-saved/Log") as the start. ..........
