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
