variables with dynamic names?

Thanks very much for your help.
I found the solution. I created a matrix with Strings and within a loop 
I read the files and processed them

wellInfo <- matrix(nrow = rows, ncol = cols)
for(i in 1:rows) {
    tempRow <- paste(rowString[i], formatC(c(1:cols), flag="0", 
width=2), sep="")
    print(tempRow)
    wellInfo[i,] <- tempRow
}

for(i in 1:rows) {
    for(j in 1:cols) {
        filename <- paste(wellInfo[i,j],".csv",sep="")
        if( file.exists(filename)) {
            file <- read.csv(filename, sep="\t", header=F)
             ...
          }
      }
}

(It was quite simple, but I did not find the "paste" command before...)
If there is something which could be done easier, just let me know.

Ciao,
Antje

Hello,

I have the following problem. I have a set of CSV files and they are 
named for a special position in a matrix (e.g. "A01.csv", "F06.csv", 
"H11.csv")

Now, I would like to read in the data of all these files and eveluate 
something for each set (and write it at the position in a result matrix).
How can I realize this with R?

Ciao,
Antje
