plot country in white if their value is zero?

[helena jam]

Guys, admittedly I am new to this, but since I spend a day looking at tutorials I now feel I can safely ask: I have values for countries, e.g. Olympic medals in gold - and most countries did not win one! But the legend always adds the faintest color to the value 0 - when i really want it to be without color! The legend and coloring should start at n= 1!
Hope you can help, and I am very pleased if you just guide me to a better tutorial/documentation!

Hi Helena,

I would suggest you change your 0s into NAs before drawing and then use the missingCountryCol option of mapCountryData(), or alternatively you can use the colourPalette option to play with the colour you want for the countries with data 0.

And then to hide some levels in the legend, you can use the options coulourVector and cutVector of the addMapLegend() function to tweak the legend to your needs of not displaying the colour for value 0.

Please post code snippet if you're still unsuccessful on this.

Regards,
