[R] Use of Sappy and Tappy for Mathematical Calculation

[arun]

Hi,

 dat1<-data.frame(ABC=c(12,24,30),XYZ=c(20,35,40))
 dat2<-as.matrix(dat1)
 #mean
 dat2mean<-apply(dat2,2,mean)
 dat2mean
  #   ABC      XYZ 
#22.00000 31.66667 
dat2sum<-apply(dat2,2,sum)
 dat2median<-apply(dat2,2,median)
 dat2max<-apply(dat2,2,max)
dat2min<-apply(dat2,2,min)

 dat2range<-apply(dat2,2,range)

dat2count<-apply(dat2,2,length)
dat2sd<-apply(dat2,2,sd)
dat2var<-apply(dat2,2,var)

A.K.

Hi,

i have a matrix like this,

ABC        XYZ    ......    .....   .....
-----         ------
12            20      ......    .....   .....
24            35      ......    .....   .....
30            40      ......    .....   .....

Here, i need to get 
                           Sum of each columns,
                           Mean of each columns, 
                           median of each columns,
                           mode of each columns, 
                           Standard deviation  of each columns, 
                           variance of each columns, 
                           range of each columns,
                           count of each columns,
                           max of each columns, 
                           min of each columns

Can i get output using sappy or tappy functions ? because there have alots
of records.

Could you please help me fast its kind of urgent !

- Thanks 
Antony
