[R] charactor matrix convert to numeric matrix

Hello R experts, can you tell me a simple way to convert a charactor matrix to numeric matrix? if I use as.numeric, the matrix is converted to a vector. a-cbind(c(23,54,65),c(1,2,3)) a [,1] [,2] [1,] 23 1 [2,] 54 2 [3,] 65 3  as.numeric(a) [1] 23 54 65  1  2  3 thanks Jian
