Hi list,

Is it possible to save the name of a filename automatically when  
reading it using read.table() or some other function?
My aim is to create then an output table with the name of the original  
table with a suffix like _out


mydata = read.table("Run224_v2_060308.txt", sep = "\t", header = TRUE)

## store name?

myfile = the_name_of_the_file

## do analysis of data and store in a data.frame "myoutput"
## write output in tab format

write.table(myoutput, c(myfile,"_out.txt"),sep="\t")

the name of the new file will be


Thanks in advanve,
