Here's an example:
/id <-
c(17,17,17,18,18,18,19,19,19,20,20,20,21,21,21,22,22,22,23,23,23,24,
24,24,25,25,25,26,26,26)
age <- rep(c(30,36,42),10)
outcome <-
c(12,17,10,5,5,2,NA,NA,NA,8,6,5,11,13,10,15,11,15,13,NA,9,0,0,0,20,
14,16,1,2,2)
mydata <- as.data.frame(cbind(id,age,outcome))
interaction.plot(mydata$age, mydata$id, mydata$outcome, fun = mean,
legend =
FALSE, lty = 1, xtick = TRUE, type = "l")/
How can I make the 'mean' summary line red and thicker?
What "mean summary line"? I count 8 lines and that matches the number
if id's with complete data.
Thanks!
