\usage{
oceColorsClosure(spec)
}
\arguments{
\item{spec}{Specification of the color scheme. This may be a
character string, in which case it must be the name of an item stored
in \code{data(ocecolors)}, or either a 3-column data frame or
matrix, in which case the columns specify red, green and blue values
(in range from 0 to 1).}
}
\description{
This function generates other functions that are used to specify colors.
It is used within oce to create \code{\link[=oceColorsTemperature]{oceColorsTemperature()}}
and its many cousins. Users may also find it helpful, for creating
custom color schemes (see \dQuote{Examples}).
}
\section{Sample of Usage}{

\preformatted{
# Update oxygen color scheme to latest matplotlib value.
library(oce)
oxy <- "https://raw.githubusercontent.com/matplotlib/cmocean/master/cmocean/rgb/oxy-rgb.txt"
oxyrgb <- read.table(oxy, header=FALSE)
oceColorsOxygenUpdated <- oceColorsClosure(oxyrgb)
par(mfrow=c(1, 2))
m <- matrix(1:256)
imagep(m, col=oceColorsOxygen, zlab="oxygen")
imagep(m, col=oceColorsOxygenUpdated, zlab="oxygenUpdated")
}
