Title
Body
I would like to use Greek characters, Latin characters and the percent sign in the facet labels of a ggplot2 bar chart. Greek characters can be done with 'facet_grid(.~variable, labeller=label_parsed)': a<-c("Delta~V","VarcoV","Delta~V","VarcoV") b<-c(1,2,3,4) d<-c("one","one","two","two") mydata<-data.frame(cbind(b,a,d)) ggplot(mydata,aes(x=d,y=b))+facet_grid(.~a, labeller=label_parsed)+geom_bar(stat="identity") Now I also want to add a facet label that includes % and a Latin character: a<-c("Delta~V","VarcoV","%V","Delta~V","VarcoV","%V") b<-c(1,2,3,4,5,6) d<-c("one","one","one","two","two","two") mydata<-data.frame(cbind(b,a,d)) ggplot(mydata,aes(x=d,y=b))+facet_grid(.~a, labeller= label_parsed)+geom_bar(stat="identity") This produces the following error: Error in parse(text = x) : <text>:1:1: unexpected input 1: %V ^ Any ideas how to include the percent sign?
