Getting ready
Suppose you are transforming a numeric vector into its logarithmic counterpart. For example, you are given the V1 vector to transform into logarithms:
V1 <- c(3, 7, -2, 6, 9, 0, -4)
The objective is to take the logarithm of V1. Notice that V1 contains a negative number and zero, which will generate an error. In this recipe, you will handle the exception using the exception handler options available in R.
