Basic statistics of a set of values #

Just in order to find that when searching for it yet another time:

Problem: You have a set of values (for instance time it took to process various queries). You want a quick overview of how the values are distributed.

Solution: Store the values in a file separated by newline, read the file with R and output summary statistics.

R: times <- scan(“times”, list(0))
Read 30000 records
R: summary(times[[1]])
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max.
   6.00   12.00   13.00   16.75   14.00 8335.00

That’s it.
