The dot in the argument means that it has to be split in R into bar=“{groupWidth:‘10%’}”. Example library(googleVis) cc <- gvisColumnChart(head(Population,10), xvar="Country", yvar="Population", options=list(seriesType="bars", legend="top", bar="{groupWidth:'10%'}", width=500, height=450), chartid="thincolumns") plot(cc) Your browser doesn’t support iframes.
