Include different options for region color palette

[johannah-pik]

Depending on the use case, different color palettes are desired for the REMIND regions.
The new region colors from this PR are optimized for distinguishability (e.g. for the REMIND validation).
For publications, grouped colors for like-wise regions could be better.

Here is a proposal from Nico for a grouped color palette, that could be implemented as an alternative choice:

OECD regions
plotstyle.add("EUR", "EU", rgb(0.0, 0.0, 0.99, 1), marker = 23, replace = TRUE )
plotstyle.add("NEU", "Other Europe", rgb(0.0, 0.0, 0.65, 1), marker = 9, replace = TRUE )
plotstyle.add("USA", "USA", rgb(0.5, 0.5, 0.99, 1), marker = 10, replace = TRUE )
plotstyle.add("JPN", "Japan", rgb(0.0, 0.5, 0.99, 1), marker = 13, replace = TRUE )
plotstyle.add("CAZ", "Can, Aus, NZ", rgb(0.3, 0.3, 0.8, 1), marker = 17, replace = TRUE )

Regions with developing and Emerging markets
plotstyle.add("CHA", "China", rgb(0.3, 0.99, 0.3, 1), marker = 19, replace = TRUE )
plotstyle.add("IND", "India", rgb(0.3, 0.65, 0.3, 1), marker = 8, replace = TRUE )
plotstyle.add("OAS", "Other Asia", rgb(0.6, 0.99, 0.0, 1), marker = 11, replace = TRUE )
plotstyle.add("SSA", "Sub-Sahra Africa", rgb(0.5, 0.0, 0.99, 1), marker = 15, replace = TRUE )
plotstyle.add("MEA", "Middle East & N. Africa", rgb(0.7, 0.2, 0.99, 1), marker = 17, replace = TRUE )
plotstyle.add("LAM", "Latin America", rgb(0.9, 0.6, 0.5, 1), marker = 12, replace = TRUE

Thanks! Maybe it is useful also to somehow group the markers. Proposal (with reference at the end):
OECD/high income regions: 15-19
China, India, OAS: 2,1,6
LAM, REF: 12, 13
MEA, SSA: 3,4

This merge request:

sorry, maybe I am a bit slow - what do you mean with "this merge" - Nico's proposal?
The option to choose a different palette (such as Nico's proposal) still has to be implemented sometime in the future, right?

[0UmfHxcvx5J7JoaOhFSs5mncnisTJJ6q]

Clarified. This is indeed a proposal, not a merge request.

Very much so, as plotstyle.add() is a destructive operation.

Somehow I remember that @dklein-pik was the master of plotstyle and the default csv file that is used. David, if so, could you up-date?

[nicobauer]

@0UmfHxcvx5J7JoaOhFSs5mncnisTJJ6q I only use plotstyle.add locally, where it does not affect the overall default values.

Yes. But you can't go back to default values. So there is no option for you to use either one or the other, except for manually setting them every time. Which defeats the purpose of the plot styles to some degree.

I am not sure what you want. But if you want to update colors you can do it here https://github.com/pik-piam/mip/blob/master/inst/extdata/plotstyle.csv
