How to get the descriptive statistic of the whole dataframe?

Hi all:
If I have a dataframe of N columns.If I wanna get the min(or max,or
mean...etc)of the whole dataframe,how to do it quickly?
What I can do is only:
min(data[,1:ncol(data)])

Any other suggestion?

Thanks!

look into the *apply series of functions. In your case

apply(name.of.your.data.frame,2,min)

or 

apply(name.of.your.data.frame,2,max)

will do. You can also put any summary function to your liking instead of
min/max.

Daniel

And summary has its own data frame method so simply

summary(name.of.your.data.frame)

There is also fivenum function and more elaborated describe in Hmisc I
believe :-)
