Dear Group, I am having trouble with using rlm on multivariate data sets. When I call rlm I get Error in lm.wfit(x, y, w, method = "qr") : incompatible dimensions lm on the same data sets seem to work well (see code example). Am I doing something wrong? I have already browsed through the forums and google but could not find any related discussions. I use Windows XP and R

Dear Group, I'm trying to build a set of new graphic device drivers. I use the devNull example a a beginning point: $ R CMD SHLIB devNull.c gcc -shared -L/usr/local/lib -o devNull.so devNull.o (everything works OK) $ R CMD SHLIB devNull.cpp g++ -shared -L/usr/local/lib -o devNull.so devNull.o (everything works OK) The difficulties start when trying to compile manually. I compile the

Hi, Could anyone tell me what is wrong: > length(unique(mydata$myvariable)) [1] 2 > and in t-test: (...) Error in t.test.formula(othervariable ~ myvariable, mydata) : grouping factor must have exactly 2 levels > I re-checked the code and still don't get what is wrong. Moreover, there is some strange behavior: /1 It seems that the error is vulnerable to NA'a, because it

I generated maps with the function symbols (graphics). These are basic maps generated with : symbols(x,y,circles=myvariable) where x et y are spatial coordinates corresponding to replicates of "myvariable". I would associate legend to this kind of maps, is it possible? Regards, Marion. -- Marion Jacquot Laboratoire de Chrono-environnement UMR UFC/CNRS 6249 USC INRA Universit? de

Hi, I am quite new to R - but quite expierience in programming. Nonetheless I have some problemes in accessing information of the "summary" object. Here is what I do: model <- lm ( y ~ myVariable ) "summary(model)" gives me an object which has a lot of information about the regression. Now I'd like to access programmatically the level of significance which is

Often it is useful to keep a "codebook" to document the contents of a dataset. (By "dataset" I mean a rectangular structure such as a dataframe.) The codebook has as many rows as the dataset has columns (variables, fields). The columns (fields) of the codebook may include: ? variable name ? type (character, factor, integer, etc) ? variable label

Hi friends - a javascript question.... Does the prototype object add some way for a class to find out the variable name of its instance variable? Or does javascript have some built in way to do this? This is confusing to describe - but if I define a variable as some object: var myVariable= new Widget(''fdfa''); can some built-in method inside the Widget class be

Dear List, Several times I use this package I get the error message shown below. When I work out simple examples, it turns out to be fine, but when working with real and moderate size data sets I always get the same error. Do you know what could be the cause of the problem? Error in apply(mod.matrix[, components], 1, prod) : subscript out of bounds Error in

I'm reading in ~3 years worth of data that includes hourly timestamps. Presumably to avoid DST confusion, all the data is in PST time zone -- no discontinuities in the spring or fall. The data comes in a csv file, which I'm reading with myvariable <- read.csv("my_data_file.csv",header=FALSE,

Hello s/r users! I've been digging around in the s- and r-mailing lists, but i actually didn't find any answer to my question. So here it is: How can i realize the following: myexec | R r_script > outfile.txt with myexec some executable writing data to stdout "cat data.txt" can serve as a test R

Would someone be able to give an example of a working use of setvar from chan_dahdi.conf? I am trying to create a custom variable like I use in sip.conf but I have been completely unsuccessful getting any variable set using setvar to appear for a DAHDI channel. I am running 1.8.11-cert8 and am using the newer format (but I have tried using the older [channels] format). Here is an example:

Greetings: I am unsuccessful in suppressing "Given : myvariable" from a coplot. There was such a question in the past but the thread breaks down. I am sure this is a "for dummies" question :-). I tried: coplot(myvar~myvar | myvar, show.given=FALSE, xlab="....", ylab="...", main=" ") and some other variations (including without main=" ")

Hello, I?m trying to leverage R_ToplevelExec to implement C level try/catch. The way it is implemented allows for running a function in a top level context. This context gets an empty handler stack, so either the function runs correctly or it jumps. When it jumps, it does not find a handler, so it jumps to the top level context. R does not allow me to call begin context and end context

Dear all, I would like to log the calls to my functions. I am trying to do this using the function match.call(): fTest<-function(x) { theCall<-match.call() print(theCall) return(x) } > fTest(2) fTest(x = 2) [1] 2 I can see "theCall" printed into the console, but I don't manage to convert it into a character to write it into a log file

Full_Name: David Bauer Version: 1.9 OS: Linux Submission from: (NULL) (160.91.245.8) In the file gram.y, the xxsubscript function generates a LANGSXP with another LANGSXP as its CDR. I believe that this is a mistake and that the second LANGSXP should be a LISTSXP. The inputs a1, a3 are parameters to the subscript function (a2), and as such they should be in a dotted-pair list.

Dear R-devs, Below is a small example of what I am trying to achieve, that is trivial in R and I would like to learn how to do in C, for very large matrices: > (mymat <- matrix(c(1,0,0,2,2,1), nrow = 2)) [,1] [,2] [,3] [1,] 1 0 2 [2,] 0 2 1 And I would like to produce: [1] "a*C" "B*c" Which can be trivially done in R via something like: foo

Dear R Community, One thing that always bugged me about R is the abundance of multi-level nested statements, like: cumsum(ifelse(c(1,diff(v)),1,0)) because: a) you have to read them inside out as opposed to left-to-right b) in the console you always have to go back and type the parenthesis if you want to nest your statement I kind of like the UNIX pipe operator as a very good abstraction of a
