For example, how would I go about entering the value e^2 in R?

The R expression
exp(1)
represents e, and
exp(2)
represents e^2.
This works because exp is the exponentiation function with base e.
-digamma(1) is the Euler's Constant in R.
e, (exp(1) in R), which is the natural base of the natural logarithm
if you want to have a little number e to play with, you can also make one yourself:
emake <- function(){
options("warn"=-1)
e <- 0
for (n in 0:2000){
e <- e+ 1/(factorial(n))
}
return(e)
}
e <- emake()
e^10
exp(10)
# or even:
e <- sum(1/factorial(0:100))
fun stuff
