I have a text string that contains text within two brackets. e.g. "testdata[3]" "testdata[-4]", "testdata[-4g]", I wish to "extract" the string enclosed in brackets? What is a good way to do this? e.g. fun(testdata[3]) = '3' fun(testdata[-4g]) = '-4g' --------------------------------- Moody friends. Drama queens. Your life?

I have an array such as: x=c(sum=77, min=4,max=9, count=5, min=4,max=9, count=8 , test=77) I wish to remove values where both the name and the value are identical. eg. i wish to end up with: x2=c(sum=77, min=4,max=9, count=5, count=8, test=77) What is the "best" way to do this? --------------------------------- Park yourself in front of a world of choices in alternative

#Is there a single function similar to "get" that works for both an object, and elements of an object ? #(I want the function to be able to return objects, and/or the deeper elements of an object.) #(i.e. elements of a dataframe and/or list)? #e.g. tempdf = data.frame(a=c(4,5,6) , b=c(10,11,12) ) templist= list(x=tempdf, y=c(1,2)) get('tempdf') #works as desired

Can anyone please refer me to all firms that offer and/or are developing a commercially supported version of R for 64 -bit Windows? - Thanks [[alternative HTML version deleted]]

Hi all, I am a new user of R and we have to integrate R into Java. I have downloaded and installed R and rJava/JRI and set up the environment. I was able to run the rTest java programs successfully. I have to automate the process involving R. I have the following question regarding it. Instead of opening the console from java program and passing commands (like load) to this console manually, is

I have searched the r-help files but have not been able to find an answer to this question. I apologize if this questions has been asked previously. (Please excuse the ludicrousness of this example, as I have simplified my task for the purposes of this help inquiry. Please trust me that something like this will in fact be useful what I am trying to accomplish. I am using R 2.4.1 in Windows XP.)

I am experimenting with some of the common r functions. I had a question re:using "gsub" (or some similar functions) on the contents of a list. I want to design a function that looks at "everything" contained din a list, and anytime it finds the text string "pattern" replace it with "x". I also wish to preserve the "structure" of the original

#Sorry for the convoluted subject line. #I have: a=c(1,2,3) x=a #example of user supplied input #Is there any function that will tell me the "name" of the object x refers to, referring only to x itself? #i.e. the "answer" I want is "a" #I want: #fun(x) == 'a' #(I don't think this is possible, but figured I'd ask.)

I have many "sample" datasets (e.g. sample 5, sample 6, etc), each identified by a number as a suffix. These datasets are saved as individual R objects on my hard drive. (e.g."Wind.5.r" . "Wind.6.r","Solar.5.r","Solar.6.r") For example purposes, I have written code that creates similar data files using the "airquality" dataset. (see

#I wish to create a "list of three dataframes" ("results2") from a "list of two dataframes" (temp) and a dataframe ("c")? #Please advise. a <- data.frame(x=c(1,2,3),y=c(5,7,9)) b <- data.frame(x=c(2,4,7,9),y=c(2,3,5,4)) c <- data.frame(x=c(22,34,7,9),y=c(52,63,5,4)) results1 <- list(a,b,c) #what I want #but this is how I need to get there
