Is it possible to use a mix of character and number as plotting symbols in R legend?
plot(x=c(2,4,8),y=c(5,4,2),pch=16) points(x=c(3,5),y=c(2,4),pch=\"+\") l
Use the numerical equivalent of the "+" character:
plot(x=c(2,4,8),y=c(5,4,2),pch=16) points(x=c(3,5),y=c(2,4),pch="+") legend(7,4.5,pch=c(43,16),legend=c("A","B"))
