Hi,
it is possible. but don't you think it will slow the code if you convert to
data.frame?
Thanks

Hi,
How about this:

There is still missing some statistics,
like sd and IQR and I prefer the output to be matrix

Hi,
is there a way I can calculate a summary statistics for a columns matrix
let say we have this matrix
x <- matrix(sample(1:8000),nrow=100)
colnames(x)<- paste("Col",1:ncol(x),sep="")
if I used summary
summary(x)
i get the output for each column but I need the output to be in matrix with
r
I also don't like to use split function because I have like around 800 columns

Error in array(0, c(n, p)) : 'dim' specifies too large an array
That is why I asked for different and faster method

Hi
Can someone show me an easy way to multiple a weighted vector with an
matrix?
example below
mat1<-matrix(sample(1:100,80,replace=TRUE),ncol=8)
w <- 1/1:10
I want the first element in w to be multiplied by the first row of mat1 and
2nd element in w to be multiplied with the 2nd row and so on.

Thank you so much for replying this could work but the problem you recreate the
