Examples

## Not run: 
# Say we wanted to get a sequential palette of oranges to reds
Pal <- 'OrRd'
n <- 5

# The most direct way is:
p.a <- city_palette(Pal, n)

# careful, though, this isnt a vector
str(p.a)
# It can be coerced to one though:
as.character(p.a)
# or
as.vector(p.a)

# The 'long' way to get the palette:
p.b <- read_cpt(cpt(Pal, n))

# ... should yield the same result as the short way:
try(identical(p.a, p.b))

# Take a look:
layout(matrix(1:2))
plot(p.a)
plot(p.b)


## End(Not run)
