Hi WizaRds, In MATLAB you can do x=1:10 and then specify x(2:end) to get 2 3 4 5 6 7 8 9 10 or whatever (note that in MATLAB the parenthetic index notation is used, not brackets as in R). The point is that 'end' allows you to refer to the final index point of the array. Obviously there isn't much gain in syntax when the variable name is x, but when it's something like

Hi All, I'm looking for some hints on idiomatic R usage using 'lapply' or similar. What follows is a simple example from which to generalize my question... # Suppose, in this simple example, I want to plot a number of different lines in different colors; # I define the colors I wish to use and I plot them in a loop: d<-

I have very large csv files (up to 1GB each of ASCII text). I'd like to be able to read them directly in to R. The problem I am having is with the variable length of the data in each record. Here's a (simplified) example: $ cat foo.csv Name,Start Month,Data Foo,10,-0.5615,2.3065,0.1589,-0.3649,1.5955

Hi WizaRds, What is the "standard" way to get the day of the week from a date such as as.Date("2006-12-01")? It looks like fCalendar has some functions but this requires a change in the R locale to GMT. Is there another way? Thanks! Jack. --------------------------------- Be a PS3 game guru.

Hi all, Are there any plans to add more functionality to command-line editing and history editing on the command line? In MATLAB (I know, comparisons are odious ...), you can type "p" and up-arrow on the command line and scroll through the recently entered commands beginning with "p". This is a very useful feature and something that I believe is not replicated in R. Please

Dear WizaRds, This is mostly a statistics question, but I'm figuring that R is the right solution (even before I start!) I have some bio data of heart rate versus time (rats taken from resting to maximal heart rate). I want to regress heart rate on time. The data have been normalized such that resting heart rate is zero at time=0, so that all curves intersect at the origin (and at the origin

[Q.] How to create an array of lists, or structures the most elegant way?

Hi, I downloaded the source code for the package zoo (zoo_1.2-2.tgz from CRAN). When I gunzip and untar the file I can't find the R / C / FORTRAN code for the library. In the R directory under zoo, the listing is for 3 files: zoo zoo.rdb zoo.rdx Is the code encoded in one of these files? I've had this problem with other packages too, trying to browse the source. Am I missing something

Hi, Could someone point me in the right direction for documentation on the following question? Let's say I have two objects a and b of classes A and B, respectively. Now let's say I write a function foo that does something similar to objects of type A and B. Basically I want to overload the function in C++ talk, so if I give foo and object of type A something (and this is my question)
