hi I've used R for many years on windows machines, but have now acquired an Asus eee 1000 linux machine. In order to get the best out of the machine, I used the 'pimpmyeee.sh' script, to get the full KDE desktop. The version of Linux is Xandros, which I believe is a close relative of Debian, but sadly I have only a nodding acquaintance with Linux at present. Naturally I want to

Hi all, I'm quite new to R and have limited experience. What Im trying to do is very important as it is part of my final year project; or more so the central idea behind it. I will be creating BibTex files to enter into a mySQL database. I then need to perform operations on this DB like 'return studies similar to x'. It's really just getting a start at this that I'm having

Dear R list members I would be grateful if anyone could guide me to a solution for fixing my rimage package problem described below.

Here is a simplistic example. sumstats <- c(mean,sd) sumstats[1] #Gives this error #> sumstats[1] #[[1]] #function (x, ...) #UseMethod("mean") #<environment: namespace:base> I thought about restricting the input to character variables such as the following sumstats2 <-

Greetings, I am not familiar with processing text in R. Can someone tell me how to read each line of words as separate elements in a list?

Hello. I am trying to write an interactive function that asks the user for a vector of observations. Unfortunately, if a user inputs a vector, R treats the vector name as a string instead of a variable. Here is an example: vector.input<-function(){ k<-as.integer(readline("Input number of vectors: ")) obs<-as.integer(readline("Input number of observations per vector
