Examples

## Create a character matrix
A1 <- matrix(c(1, 2, 3, "a", "b", "c"), ncol=2, nrow=3)
#      [,1] [,2]
# [1,] "1"  "a" 
# [2,] "2"  "b" 
# [3,] "3"  "c"

## Convert it to an Ryacas matrix for symbolic calculations
A2 <- sym(A1)
# {{1, a},
#  {2, b},
#  {3, c}} 

## Convert it back to a character matrix
as.matrix(A2)
#      [,1] [,2]
# [1,] "1"  "a" 
# [2,] "2"  "b" 
# [3,] "3"  "c"
