[1] "expression" [1] "character"
Example 2:
# R program to convert # expression to character # Creating an object of expression class x < - expression( 2 ^ 3 ) # Evaluating the value of object eval (x) # Calling deparse() Function x1 < - deparse(x) # Evaluating the value of object eval (x1) |
Output:
[1] 8 [1] "expression(2^3)"
