Re: [R] ggplot: Can plot graphs with points, can't plot graph with points and line

Hi John, This should do what you want. I've changed your data.frame name for my own convenience to "dat1". ###=== dat1 <- data.frame( Time = c("Age.25","Age.35","Age.45","Age.55"), Medians = c(128.25,148.75,158.5,168.75) ) # create segments data.frame

Hi John, I'm not sure how to do this with ggplot, but: Time<- c("Age.25","Age.35","Age.45","Age.55") Medians<-c(128.25,148.75,158.5,168.75) > is.character(Time) # [1] TRUE - thus it has no intrinsic numeric value to plot > is.numeric(Medians) # [1] TRUE # coerce Medians to factor and then plot aga
