Colour palettes for data, based on some well known public data sets.
palr provides colour palettes for data, based on some well known remotely sensed data sets for sea ice concentration, sea surface temperature and chlorophyll-a.
There are four main ways of working with palr palette functions, which have names like
sstPal for ice, chlorophyll-a and sst respectively and
mk_timePal for creating a time-mapped palette function.
icePal(n)return n colours from the palette
icePal(data)return the right colour for values in
icePal(palette = TRUE)returns the entire palette, with colours
tfun <- mk_timePal(datetimes, pal); plot(x, tfun(dt))match date-times to a palette, or palette function.
There is a vignette illustrating basic usage, this can be read on CRAN or loaded from within R.
Run this code to load the vignette within R:
