R Help: I have read a number of tables into R with identical headings and I would now like to make a single table that has all the data appended under this single heading line. for example: t1 <- read.csv("f1",header=TRUE) t2 <- read.csv("f2",header=TRUE) all <- c(t1,t2) #all is now twice as wide as t1 or t2 with the same number of row!!!! #I need to know how

R-help, I would like to place nine (3X3) plots per page. I am not properly implement mfrow(3,3) in the script below: jpeg("xyplot.jpg") #names output file my_args <- commandArgs() #sets up to take args from dos batch command mfcol(3,3) #set page for 3X3 TEMPS <- c(-15,25,85)#list of temps VBATS <- c(3,3.6,4.7)#list of Bats BOARDS <-

R-Help, I am trying to do simple plots of the characteristics of cellular phones. I am values that fit along an axis that has many data points around 800 and 1800. I am not interested in the "dead space' between the two clusters of data. I am not interested in a linear axis. I would like to "cut out" the white space between the two pockets of data when plotting. I

R-Help, I am trying to reduce at data set to rows where a specified value occurs in a specified value.

R-Help, I am executing a R script and would like to put multiple plots into a single file. For some reason the contents of plotfile.jpg always seem to contain the last plot and not all plots. If I do same thing with pdf, a multiple plot file is created. Can you help me? Regards, Bill Bill Hunsicker RF Micro Devices 7625 Thorndike Road Greensboro, NC 27409-9421 bhunsicker at rfmd.com

Hi, folks: I am running 64-bit R on a 64 bit machine under 64 bit Windows 7. I'd like to try the package ff, but it is not clear to me whether the current version of ff will work in a 64 bit environment. The windows version is "compiled," which suggests that there is more than just R p-code. Do any of you know whether the current compiled version of ff will work in my

Greetings, all: I am using factanal in R. When I enter a matrix or a formula, the print method winds up with something like this: Test of the hypothesis that 6 factors are sufficient. The chi square statistic is 28.1 on 22 degrees of freedom. The p-value is 0.172 But when I enter a covmat, the print method winds up with something like this: The degrees of freedom for the model is 22 and the

Hello, everyone I have a piece of code that looks like this: mrets <- merge(mrets, BMM.SR=apply(mrets, 1, MyFunc, ret="BMM.AV120", stdev="BMM.SD120")) mrets <- merge(mrets, GM1.SR=apply(mrets, 1, MyFunc, ret="GM1.AV120", stdev="GM1.SD120")) mrets <- merge(mrets, IYC.SR=apply(mrets, 1, MyFunc, ret="IYC.AV120",

Hi, I would like to evaluate a function, with 3 arguments, for instance, myfunc<-function(a,b,c) { sqrt(a)-exp(b)+4*c } How to execute myfunc(x,y,z), for all x, all y and all z, where x,y,z are vectors?

Can someone help me with this simple example? sq <- function() { y <- x^2 y } myfunc <- function() { x <- 10 sq() } myfunc() executing the above in R yields: > myfunc() Error in sq() : Object "x" not found I understand that R's scoping rules cause it to look for "x" in the environment in which "sq" was defined (the global environment in

Hi all, is there a way to extract the name of a function, i.e. do the reverse of match.fun applied to a character string? I would like to print out the name of a function supplied to another function as an argument. For example: myFunc = function(x) { x+1 } applyFunc = function(fnc, x) { fnc = match.fun(fnc) fnc(x) } Is there a way to obtain "myFunc" from the argument fnc in

Dear all, It has been ages since I studied integration in college. Right now I try to recover all this kind of knowledge and then try to understand how integration works. Thus I am doing some first 'experiments' and I would like to request your help and comments. I have the function: p2<-function(x){0.5*(3*x^2-1)} # I found the square of p2 by using some pencil and

Hi, Suppose I have a function: myfunc <- function(x, y) { ... } And within the function I want to print out the name of the x, y vectors. For example, if I do: > myfunc(foo, goo) [1] "foo" "goo" It shall return "foo", "goo" (with or without quotes is fine), where foo and goo are two vectors with numbers. I know this sounds strange, but I'd

Dear R users, I want to retrieve "..." argument values within a function. Here is a small exmaple: myfunc <- function(x, ...) { if (hasArg(ylim)) a <- ylim plot(x, ...) } x <- rnorm(100) myfunc(x, ylim=c(-0.5, 0.5)) Error in myfunc(x, ylim = c(-0.5, 0.5)) : Object "ylim" not found > I need to retrieve values of "ylim" (if it is defined

Dear R Helpers, I have about 20 data frames that I need to do a series of data scrubbing steps to. I have the list of data frames in a list so that I can use lapply. I am trying to build a function that will do the data scrubbing that I need. However, I am new to functions and there is something fundamental that I am not understanding. I use the return function at the end of the function and

Dear all, I'm having a problem with debugger() in both R 2.8.0 and R 2.12.0. Probably also versions in-between. I don't see it logged in the bug database, but it's hard for me to imagine that no-one else has encountered it. So my question is whether it's a known problem with a workaround, or do I log it as a new problem? The situation is that if I use

When using ORC JIT, I'm having trouble with external function resolution (that is, of a function defined in the app, with C linkage). I add a declaration for the function to my IR, and when I use MCJIT, it finds it and all is well, But when I use ORC JIT (I *think* correctly, at least it closely matches what I see in the tutorial), I get an LLVM error, "Program used external function

Hi, I was reading about the Yahoo! library recently and was really excited by the idea that I wouldn''t have to branch for IE in my event handlers. Is there any chance that such abstraction will come to Prototype? Thanks, Sam

Dear R-guRus: I would like to pass variables to a function in R in "by reference", e.g Fortran style. For example, suppose I have the following code x<-c(1:10) y<-1 MyFunc<-function(x,y) {y<-sum(x); return(NULL)} MyFunc(x,y) print(y) in this case print(y) will produce "1" instead of 55 (which is sum(x)) - how do I make sure that afte the function is run, y
