HI,
You could try this:
set.seed(125)
x <- matrix(sample(1:80),nrow=8)
colnames(x)<- paste("Col",1:ncol(x),sep="")
sapply(data.frame(x),function(x) summary(x))
# Col1 Col2 Col3 Col4 Col5 Col6 Col7 Col8 Col9 Col10
#Min. 10.00 1.00 17.00 3.00 18.00 11.00 13.00 15.00 2.00 6.00
#1st Qu. 24.75 29.50 26.00 7.75 40.00 17.25 27.50 34.75 24.50 12.50
#Median 34.00 46.00 42.50 35.50 49.50 23.50 51.50 51.50 33.50 48.00
#Mean 42.50 42.75 41.75 35.75 44.88 26.88 44.75 50.12 34.88 40.75
#3rd Qu. 67.75 58.50 50.00 63.25 54.25 30.25 56.25 70.50 45.25 63.00
#Max. 74.00 77.00 76.00 70.00 65.00 63.00 79.00 80.00 71.00 72.00
