Examples

# The usual version of 'switch' works perfectly with one value
x <- "a"
switch(x, a = 1, b = 2, c = 3)

# But not with more than one
x <- letters[1:3]
## Not run: switch(x, a = 1, b = 2, c = 3)

# vswitch works well where you'd like to 'switch' a vector
x <- letters[1:3]
vswitch(x, a = 1, b = 2, c = 3)
