That does the trick with base functions! Thanks Dennis.

Hi: Try mydf <- data.frame(let=rep(letters[1:3],each=3), num=rnorm(9), stringsAsFactors=FALSE) stripchart(num ~ let, data = mydf, pch = 19, vertical = TRUE) Dennis On Thu, Mar 17, 2016 at 3:29 AM, Ivan Calandra <[email protected]> wrote:Dear useRs, I would like to plot data points in a simple scatterplot. I don't have a lot of data per category, so a boxplot does not make sense. Here are some sample data: mydf <- data.frame(let=rep(letters[1:3],each=3), num=rnorm(9), stringsAsFactors=FALSE) I would like to do that, which throws an error, most likely because x is character: plot(mydf$let, mydf$num) If I convert to factor(), it plots a boxplot with no possibility (AFAIK) to plot points: mydf$let <- factor(mydf$let) plot(mydf$let, mydf$num, type='p') I know I can use the function points() in a somewhat convoluted manner: plot(mydf$num, xlim=c(1,3), type='n', xaxt='n') axis(side=1, at=1:3, labels=levels(mydf$let)) points(as.numeric(mydf$let), mydf$num) Isn't there a simple(r) way? Maybe I just missed something obvious...
