[R] Count of elements in coulmns of a matrix

[arun]

Hi,

Try this:

list1<-list(ABC=c(2,5),XYZ=c(3,4,4,2),PQR=c(4,5,3))
> lapply(list1,function(x) length(x))
$ABC
[1] 2

$XYZ
[1] 4

$PQR
[1] 3

 list2<-lapply(list1,function(x) length(x))
 dat2<-data.frame(list2)
 dat2
  ABC XYZ PQR
1   2   4   3
A.K.

Subject: [R] Count of elements in coulmns of a matrix

Could you please tell me what is the function or method to get count of
elements in all the columns in a matrix ?

for eg :-

ABC      XYZ    PQR
------      -----     ------
2            3            4
               4           5
5            4           3
              2

Result will be like
ABC      XYZ    PQR
------      -----     ------
2             4            3

Could you please help me ?
