To calculate basic descriptive statistics, one would have to type one of:

r summary file.txt
r summary - < file.txt
cat file.txt | r summary -

For each of average, median, min, max and std deviation, the code would be:

seq 1 100 | r mean - 
seq 1 100 | r median -
seq 1 100 | r min -
seq 1 100 | r max -
seq 1 100 | r sd -

Doesn't get any simple-R!
