Hi,
Is there a way to get different colour based on group when plotting stripchart?
mydata <- data.frame(val1 = c(1.1, 3.2, 4.1, 2.5, 6.2, 5.3, 4.5, 2.2,
4.7, 2.7), val2 = c(4.2, 5.3, 3.4, 2.6, 5.3, 6.2, 7.7, 4.8, 3.4, 2.1),
group = rep(0:1, 5))
mydata.stack <- stack(mydata, select=-group)
stripchart(values ~ ind,
data=mydata.stack,
vertical=T,
at=c(1.25, 1.75),
pch=15,
col="red")
I would like to get different colour for the two groups (based on
group variable). I tried something like
stripchart(values ~ ind,
data=mydata.stack,
vertical=T,
at=c(1.25, 1.75),
pch=15,
col=c("red", "yeallow")[mydata$group])
with no luck. Thanks.
