similar to: does R provides a wait or pause function?

Hello, In order to increase the performance of a script I'd like to sort very large vectors containing repeated integer values. I'm not interesting in having the values sorted, but only grouped. I also need the equivalent of index.return from the standard "sort" function: f(c(10,1,10,100,1,10)) => grouped: c(10,10,10,1,1,100) ix: c(1,3,6,2,5,4) is there a way

Full_Name: Marc Mamin Version: 1.8, 2.0.0 OS: Windows & Linux Submission from: (NULL) (217.17.202.254) Using only the beginning of a column name will match it: >aaa<-1 >df<-as.data.frame(aaa) >names(df) [1] "aaa" >df$a [1] 1 !!!!!!!!! (I expect df$a to be undefind) >df$x >NULL Compare with: > df["aaa"] aaa 1 1 > df["a"]

Hello, I'm looking for a function that counts the occurences of a given character within a string. f('|','ab|c|d') => 2 More precisely, I need to complete a vector of strings to ensure that all elements have the same count of a "separator": a|b|c a |a|b|c|d => a|b|c|| a|||| |a|b|c|d I guess that scan makes use of an internal function that would do

Hello, I would like to have a function that retrieve matching strings in the same way as with java.util.regex (java 1.4.2). Example: f('^.*(xx?)\\.([0-9]*)$','abcxx.785') => c('xx','785') First of all: Is it possible to achiev this with grep(... perl=TRUE,value=TRUE )? As I would call this function very often with large data, I'm reluctant to use Sjava

Hello, I'm looking for a fast way to retrieve the position of elements from a vector which match element in another vector. Example va<-c('a','e') vb<-c('a','b','c','d','e','f','e') f(va,vb) should return c(1,5,7) I have 2 different cases: I) my vector vb contains only distinct values II) my vector vb may

Dear r-helpers!

Hi, As the server www.omegahat.org seems to be down since quite a while, could someone send me the RSXML library for Windows2000 ? Many thanks, Marc Mamin

Hallo, I'd like to add grid lines to a lattice graph having 2 series of Y data. See these 2 examples: data(iris) [1] xyplot(Sepal.Length + Sepal.Width ~ Petal.Length , data = iris, allow.multiple = TRUE, scales = "same",type="l", ) [2] xyplot(Sepal.Length + Sepal.Width ~ Petal.Length , data = iris, allow.multiple = TRUE, scales =

Hi, I have a strange issue under W2K; consider these two code extracts: 1) if(condition a){ trellis.device(png,filename = filename_a,... xyplot(... dev.off() } 2) if(condition a){ trellis.device(png,filename = filename_a,... xyplot(... } dev.off() In 1), The png file is generated, but empty; in 2), where I've taken the dev.off clause out of the condition block, my plot is

Hi, R is very new for me, so excuse if my questions are too basic... BTW, are there any forum where new R users could get help without annoying this huge mailing list ? In following code, I'd like to choose the color for each of the curve diplayed. png(filename = filename, width = 950, height = 600, pointsize = 10, bg = "white") xyplot(HITS+MS1*3+FREQ~TIME

Hi, thanks for this great work. Just a minor point - maybe you should mention the rm -rf $FAKE_ROOT command within your README file: It caught me unexpected and I was looking a couple of minutes for the package artifact before I actually read the last line.

http://dlc.sun.com/osol/on/downloads/b114/ This URL makes me think that if I just sit down and figure out how to compile OpenSolaris, I can try b114 now^h^h^h eventually ? I am really eager to try out the new quota support.. has someone already tried compiling it perhaps? How complicated is compiling osol compared to, say, NetBSD/FreeBSD, Linux etc ? (IRIX and its quickstarting??) --

I would like to have a function which gets data, does a calculation and prints a result and then waits some number of seconds and repeats. If I use Sys.sleep, the execution is pausing but the function output is buffered so that it all comes out when the function terminates. How can I get output while the function continues to execute?

I've been playing with a quincunx animation in R 1.2.2 and would like to have finer control over the speed of the animation. I know that I can use system("sleep 1") on unix systems at least, but it would be nice to have something like pause(.01).

Dear all, I've found this nice code fragment on the web (from Jan T. Kim if I'm correct): hitReturn <- function(msg) { invisible(readline(sprintf("%s -- hit return", msg))); } But it does not seem to work in non-interactive mode ( I mean, when I start a script like this: R --vanilla < script.R ) It simply continues, I guess the stdin is not connected?

This is going to look silly, but I've seen it asked so many times that I'm starting to think it should be included in the OpenSSH distribution. People want to set up persistent tunnels without having to keep a shell open. The following program can be used with -f to do just that: #include <unistd.h> int main() { pause(); return 0; } Any chance of this making it
