I have a matching problem that I cant solve. mystring = "xxx{XX}yy{YYY}zzz{Z}" where "x","X","y","Y","z","Z" basiclly can be anything, letters, digits etc. I'm only interested in the content within each "{}". I am close but not really there yet. library(gsubfn) strapply(mystring,"\\{[^\\}]+",, perl=F)

Hi I have this vector of strings. MyData <- c("Test1","Test2","I(Test1^2)","I(Test2^3)","I(Test1.Test2^2)") where I want to extract only the text after "I(" and before "^" so that the string returned only contain c("Test1","Test2","Test1.Test2") I am not very skilled in the use of matching

Does anyone know how this is don? I have a large matrix where I extract specific columns into txt files for further use. To be able to keep track of which txt files contain which columns I want to name the filenames with the column Id's. The most basic example would be to use an for() loop together with paste(), but the result is blank. Not even NULL. this is the concept of thecode i use:

Hi I have a timeSeries object (X) with monthly returns. I want to display the returns with a barplot, which I can fix easily. But my problem is labaling the x-axis, if I use the positions from the timeseries It gets very messy. I have tried rotating and changing the font size but it doesn't do the trick. I think the optimal solution for my purpose is too only display every second or third

Hi I wonder if there's a smarter way to do this procedure. I have a vector of filenames wher I only am interested in the first part of the filename. I would use the following method of extracting the first part. But is there a more simple way of doing this? Names <-

Hi I have this problem where I need to find if there is any numbers in a string, this is no problem if theres only one number per string. I would then simply use the regexpr() funtion togheter with the substring function to extract the number. But regexpr only picks one number per string either from the beginning or the end, but not multiple. Can this be done? And how for example My string <-

Hi Does anyone know if its possible to add pagebreaks to an pdf through an R command? I'm running a loop where each session exports an pdf graph. Each image becomes a separate file, but I would like to have them in the same document but on separate pages. Does anyone know a solution or workaround? Regards, Tom -- View this message in context:

Hi When I'm looding the library "uroot" something happens with the basic R code that handles numeric classes. Its looks like a bug but I cant isolate the problem. So hopfully one of you smart guys out there can give me some help. This is how the problem looks. Take for example the vector TEST <- c("1","2") which I want to transform it to a numeric vector. I

Hi R gurus Im currently doing some GUI coding with the rpanel package. I have come across a very interesting problem, how do I close a panel that I have created. This sounds silly for I can always click the X up in the right corner but how do I do it by code? for example; when I create a control I know the objects name. test = rp.control() and test will have this format

Hi Im pretty new to R and I have run in to a problem. How do I name all the levels in this list. Lev1 <- c("A1","A2") Lev2 <- c("B1","B2") Lev3 <- c("C1","C2") MyList <- lapply(Lev1,function(x){ lapply(Lev2,function(y){ lapply(Lev3,function(z){ paste(unlist(x),unlist(y),unlist(z)) })})}) I would like to name the different

I am currently using S+, which is my company standard econometric package, but unfortunately in some areas R has a lot more to offer in nice functions/libraries. Libraries I would like to use in S+. So I would like to use the R functions by calling on R from S+. For example export the data to be used in the R calculation in a temporary txt-file, and then S+ calls on R to start and read the txt

This might not be the correct forum for this question for there might be some flaws in my logic so the R function I'm looking for might not be the correct, but I know there?s a lot of smart people in this forum so please correct me if I'm wrong. I have been googling and searching in this forum for something useful but so far I'm out of luck. This is the background to my problem. I
