R programming: How do I get Euler's number?
Solution 1:
The R expression
exp(1)
represents e, and
exp(2)
represents e^2.
This works because exp is the exponentiation function with base e.
Solution 2:
-digamma(1) is the Euler's Constant in R.
e, (exp(1) in R), which is the natural base of the natural logarithm
