Forgive this naive question, but I'm not accustomed to using Win ports of Unix tools (actually I'm unfamiliar with Unix tools, period). Anyway, I've successfully compiled the R-1.1.1 sources into the full binary package. Everything seems to work. I'd like to remove all the "made" files and leave only the original source code and the compiled binary code. Is there

Hello, I have been banging my head against the wall trying to figure out this seemingly simple problem with no success. I'm hoping that one or some of you can help. Here is the code I am trying to use: #importing data data.file <-read.csv("/file/location", header=TRUE, sep = ",") #selecting a subset of data based on variable "Sample" data.subset1 <-

Hello, I apologize in advance for not providing sample data, I'm a very new to R and can't easily generate appropriate sample data quickly. I'm hoping someone can offer advice without it. This code below works and does what I want it to do, which is for a given row in my dataframe, where the variable "peak.cort" = max, it makes the value of another variable

Hello to everybody, I just subscribed to this list. I find R a really nice environment for statistical analysis. I started to use it some days ago. I use it at home in my Linux box, but I would like to use it in my institute in my Digital Alpha (my machine runs OSF1 V4.0). I tried to compile the distributed source code, without success due to some errors. And the binary available is in RPM

As part of my work, I am trying to append matrices onto data frames. Naively I assumed that when rbinding a data.frame and matrix, the matrix would be coerced and appended, keeping the names from the data frame. Clearly, I am not fully understanding the process by which rbind works. Example code: > A<-data.frame(1,1,1); names(A)=letters[1:3] ; B<-matrix(0,2,3) > rbind(A,B)

Peter, I am trying to get memdisk to work with grub and have run into a problem. Grub loads memdisk into the 0x9000 segment and then starts it at location 0x90200. I run into problems in the first printf statement. It turns out that printf uses a switch statement that compiles into a jump table. When I reach this jump table, I believe the code is jumping into hyperspace due to the jump table

Hey friends, I need a little assistance getting one of my applications running on OSX. I am able to install everything, and get my application running, but when I try to store an object in the session in one of my apps, the session object doesn''t get stored.

Please help, I have an application I switched over to UTF-8, but I am unable to decode URLs with unicode characters in them properly. For instance, if I have "item=Pur%E9ed" as a parameter in my url, when it''s decoded by rails, it returns "Pur?ed" and not "Pur?ed". Is there an easy way to fix my controller to accept these characters properly?

Does anyone out there have any thoughts on the type of load common DTrace scripts would cause on a system if run 24x7? I know "common DTrace scripts" and their underlining probe calls a vague statement. So for the lack of a common and establish set of scripts in the OS, I''ll use the most popular right for my question...the DTraceToolkit from Brendan Gregg. Which by the

Please help, Does anyone know how to override the Mongrel request URI limits built in? I know it was set at a 512 byte limit, but my application will not work with this in place.

I have a function that is called from a "sourced" script, whenever certain conditions are met. I have this inside it: if(P > 0.9)save( file = today() , myLMSmodel ); This gives me files that look like this: Thu Jan 8 14:04:43 2009 That works fine on my Mac, but it would be much more convenient to have something like this: LMSMOD_Jan_08_09_1404 Does anyone know how I can do

Hi, What is the required size of the echo residue buffer in speex_echo_cancel function? The mdf.c source would suggest that it's frame_size + 1, while preprocessor.c source claims it's frame_size. Bug? Or am I missing something? I am using 1.2beta1. Thanks, Gregg

I've decided to install in R in a directory other than /usr/local, but I'm having difficulty in setting the correct paths, i.e. PATH or path. I've set my R_HOME, and sure enough there's a bin and lib directory there but R just won't execute (something like GUI 'X11' is not supported. However when R is installed in /usr/local then everything is OK...Any help or comments
