summary of summaries

Hi,



 I have a few hundreds files with numerical information of different length
 but with the same column structure. I use the following code to get summary
 statistics



 fplist <- list.files(pattern=".*analysis")

 for (fp in fplist){

            x2 <- read.delim(fp)

            summary(x2)

 }



 Summary gives something like:

 summary (x2)

       V1              V2            V3              V4                  V5
 V6                V7               V8               V9

 Now I want to get a summary statistics of the summaries. Obviously I would
 need to store the summary results inarrays. But I was wondering if that
 makes sense and how an expert would solve this? I don't want to create an
 array for each column if possible.



 Thanks for the kind support,



 Bernd
