[R] number of an element in a matrix

[Horace Tso]

My last email went out faster than I could think. Actually no need to coerce a matrix to a vector.

x = matrix(sample(1:10, 100, replace=T), ncol=10)
table(x)

How about

x = matrix(sample(1:10, 100, replace=T), ncol=10)
table(as.vector(x))

Hi, I wonder if there is any function which gives the number of times which
an element is repeated in the matrix. Let say there is a matrix, I would
like to find out how many times number 2 has been repeated in the matrix, or
in other words, how many elements of the matrix are equal 2.
Thanks for your help,
Rostam
