It seems that it is not possible to color points that way using
stripchart. I found a workaround which solved the problem:
stripchart(values ~ ind,
data=mydata.stack,
vertical=T,
at=c(1.25, 1.75),
pch=15,
col="white")
points(rep(1.25, nrow(mydata)), mydata$v
I was probably too vague. I meant that the group variable descirbes
the group (eg. different individuals) and val1 and val2 are just two
variables measured from eg. individual.
> mydata
val1 val2 group
1 1.1 4.2 0
2 3.2 5.3 1
3 4.1 3.4 0
4 2.5 2.6 1
5 6.2 5.3

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
