How to get the descriptive statistic of the whole dataframe?

Hi

 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.
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 :-)
There are at least 3 different describe functions, all useful, but 
with somewhat different output

describe (psych)
describe (Hmisc)
describe (prettyR)

One of these will probably do just what you want.
