I see a lot of examples in javascript but I cannot find an example to do it in R
Here is the api link: http://api.highcharts.com/highcharts#global
I am tryin
As of version 0.5.0 of highcharter, it seems the option highcharter.options is not there any more, but there are several separate options, e.g. highcharter.lang, highcharter.global, etc. So the following approach works:
lang <- getOption("highcharter.lang")
lang$decimalPoint <- ","
lang$numericSymbols <- highcharter::JS("null") # optional: remove the SI prefixes
options(highcharter.lang = lang)
In addition to changing the decimal point, the SI prefixes ("k", "M", "G", etc.) are turned off by setting the numericSymbols to null, see Replacing/removing the metric notations like thousands "k" abbreviation.
