Subject: [Rd] [R] how to extract the column name or value from the
 numerical value of the matrix
Message-ID: <s32ec37c.088@lp-msg1.co.ihc.com>

look at ?col and ?row.  One way to use them is:

col(A)[A==11]
row(A)[A==14]

hope this helps,

Dear sir,
 i have a matrix like
 x<-c(1:20)
A<-matrix(x,4,5)
> A
     [,1] [,2] [,3] [,4] [,5]
[1,]    1    5    9   13   17
[2,]    2    6   10   14   18
[3,]    3    7   11   15   19
[4,]    4    8   12   16   20
