color_values() modifying global environment? about colourvalues

I think this was directly related to #24 - I missed a clone statement.

Please try the latest version from github

devtools::install_github("SymbolixAU/colourvalues")

Then you should see the expected behaviour

library(colourvalues)

set.seed(123)

x <- runif(10,-10,10)
y <- x
x
y
z <- color_values(y, palette = get_palette("cividis")[256:1, ] )
x
y
z

Note also that colourvalues has a get_palette() function for getting various palettes.

Thanks very much, @SymbolixAU. The GitHub version does indeed resolve the issue. I gather the clone statement is on the C++ side, so I'll shield my eyes and pretend I never saw this. :-)

And thanks for the tip about get_palette(); I knew there were various options but I wasn't clever enough to figure out how to reverse the direction.

yeah it's a C++ thing :)
