Hi, I have a data frame with 100 variables (numeric and non numeric types), and I want to join them in only one column, like a vector, but i want to keep the non numeric variables like they are.

Hi, I just recently changed my OS to Ubuntu 12.04 (32bit). Now I tried to install some packages required by my old and working scripts. Unfortunately I fail when trying to install the package "xslx". Maybe it is related to the 32bit version of my R (its not possible to install a 64 bit version). Can anyone help me to sucessfully install xslx? Here some console output (e.g.

Given: > filename<-paste(tempdir(),"\\","myfile.txt",sep=""); > sub("\\\\","/",filename); [1] "C:/DOCUME~1\\AJAYAS~1\\LOCALS~1\\Temp\\Rtmp2f270T\\myfile.txt" Note: Only the first occurence of \\ is replaced. What is the syntax for replacing every occurence? Thanks. [[alternative HTML version deleted]]

Hi, I got a small problem on how to define the vector index without manually inspect the vector. example: y=c(2,3,5,2,4,6,8,3,6,2,5) #I have ten set of this kind of vectors (with different values but same length) that I would also like to run the routine below #say; v=the first index in y where the value is larger than 4, in this case index 3, value 5 #what I would like to do is take y[1:v]

Hi! I would like to post the following question: I was trying to figure out how to do the simulation shown in Fig 10.6 of John Verzani's book 'Using R for Intro Statistics'. It is on page 290, with a description on the previous page. It seems like a simple thing... Just needing to duplicate a procedure. (Perhaps I need to do it with a loop?) This is what I was trying:

Hello R Community, I don't post to these things often so excuse me if I stumble on my forum etiquette. This is a complex problem for me, which may require two forum entries, but I will try my best to be concise. Also, I am a self taught coder, so if my code is not to convention, your constructive criticism is always welcome. I need to split up a data frame by participant (gpsarc -

Hi, I have a 1-column dataframe with rownames and I want to sort it based on the single column. The typical procedure that is recommended in diverse posts is to use order in the index. But that "destroys" my dataframe structure. Probabaly it is a very simple solution. Here is a short reproducable example: x <- c(1,3,51,2,34,44,12,33,2,8) df <- data.frame(x) rownames(df) <-
