Hi all, I created environment "mytoolbox" by : mytoolbox <- new.env(parent=baseenv()) Is there anyway I put it in the search path ? If you need some background : In a project, I often write some small functions, and load them into my workspace directly, so when I list the objects with ls(), it looks pretty messy. So I am wondering if it is possible to creat an

Hi, I am writing a function and need to pass a function expression as an argument, for instance, myfun <- function( express) { x<- c(1,2,3) y<-express } if I call the above function by myfun( x*2 ), I get 2 as the result, instead of 2,4,6 , could someone help me to fix this problem ? Furthermore, is that

Hi all, I met a problem while using the debug package, I have the following program: mainfun<- function(){ beta<-1 result<-subfun(beta+x) } subfun<-function(expr){ y <- eval(expr, envir=list(x=c(1,2)),enclos = parent.frame()) return(y) } I have no problem using this program without calling the debug

Hi, I am trying to output a R data set for use in WinBugs, I used dput(list(x=rnorm(100),N=100),file="bug.dat") But I can't get the intended format: list(x=c(.......),N=100), instead, I got something like this (copied the first two lines): [00000000]???73?74?72?75??63?74?75?72??65?28?6C?69??73?74?28?78???? structure(list(x

Did some search but couldn't find useful result. I am trying to read a n*m dimension data with read.table, what i need is a numeric array, is there any efficient way to allow me get this array directly instead of a list? I tried to use as.array() to change the mode, but seems it doesn't work and i got this error message: "Error in "dimnames<-.data.frame"(`*tmp*`,

Hi, I would like to assign a value to a member b of the list a in position 3, by calling: assign( target, 2.34, 3) My question is what the "target" should be. I tried target <- paste("a", $, "b") and something else, but haven't got the right answer yet. BTW, if I attached a list named

Hi All, I have been struggling to figure out how to compile c codes for R use. I am using Win XP + Cygwin + R binaries. After I followed all the instructions in " Building R for Windows" from Murdoch's website, I tried to Run something like : R CMD SHLIB C:\R\test.c , but still didn't get any output. My first question is, does this mean I already did

Hi All, For the following code, I'm not sure why the error bars are appearing horizontal. Can someone please tell me how to fix the problem. testdata <-

Assuming I have a matrix of data (or under some restrictions that will become obvious, possibly a data frame), I want to be able to apply a list of functions (initially producing a single number from a vector) to the data and produce a data frame (for compact output) with column 1 being the function results for the first function, column 2 being the results for the second function and so on - with

Hi you guys: I have been wondering if there is any way to change the labeling in plot.ts( ), for example , if I plot two sequences, i always got y labels as "series1", "series2", I tried to use ylab=c((expression(mu_1)),(expression(mu_2))), but it doesn't work. thanks in advance for any help best.

Hi, I have a data set (data frame) describing some features of the students in a high school in the following format: Stu ID Year feature 1 feature 2 ............. 1001 1990 1001 1991 1001 1992 1002 1990 1002 1991 1002 1992 Some features of a few of these students are missing, I would like to

Hi, I just realized that in Matlab, as long as memory is pre-allocated, doing for-loop doesn't cost more time than doing things in vector form. But it seems in R, it still cost a lot to do for-loop. Is there any improvement in R that I missed. Thanks a lot. Merry Xmas Everyone !

Hello, everybody: I recently encountered an example with in which the graph was placed in a way that did not leave room for a legend. Maybe you would describe it as "legend too big", I'm not sure. I found myself wishing I could force in some space after the title. Here's working example where I'd like to make room for a legend. x <- rnorm(100) hist(x, freq=F,

How do you calculate T and P statistics (T- test) in R? Is there a package out there that can do these calculations?

Dear R users, I am trying to do the forest plot follow the function given on web. However, the order of the tests has been sorted alphabetically. I would prefer keeping the order as data frame input so that I can group and compare (from the graph) the target immune NS1, IgG and IgM (where SD, BioRad, Pb etc are the brand names) > d x y ylo yhi SD.NS1

Dear List: A few weeks ago I posted some questions regarding data simulation and received some very helpful comments, thank you. I have modified my code accordingly and have made some progress. However, I now am facing a new challenge along similar lines. I am attempting to simulate 250 datasets and then run the data through a linear model. I use rm() and gc() as I move along to clean up the

hi R users I have a large 1D dataset and some of them is NA value . I found I cound get the spectrum by such a command. ua=c£¨10£¬30 £¬40£¬50£¬NA£© spectrum(ua) and I could not use na.rm just like mean or sd function How could I get the spectrum of ua ? thank you . -- TANG Jie [[alternative HTML version deleted]]
