hello everybody,

I have a directory with over 3000 files with different names. I would like 
to make some vectors with the file names which are belong together.

I'm trying to do it with a for loop in R:

SF <- c("ad", "cd", "cer", "stress", "salty", "PC", "high", "transfer", 
"cold", "heat") # the pattern to look for
names(SF) <- as.vector(SF)
for (i in 1:length(SF)){
        write(names(SF)[i], "")
        for (j in 1:length(SF))
                {list[j] <- grep(names(SF)[j], list.files(),value=TRUE) 
#character vector with the specified stress factor
                }
        }

but all I'm getting is this 

Error in list[j] <- grep(names(SF)[j], list.files(), value = TRUE) : 
  object of type 'builtin' is not subsettable

I would like the loop to make  in each round a list of the files with the 
pattern in the directory I'm looking in.

what am i doing wrong?

If I doing it for each element I'm getting the correct list.

THX for the help

Best Regards

Assa Yeroslaviz
