[R] plot numeric vs character
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?

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...

I haven't been following the thread but! If you want to use lattice xyplot # create x values in their right position -- # assuming equal spacing mydf$x = rep(1:3, each = 3) library(lattice) xyplot(num ~ x, mydf, scales = list(x = list(at = 1:3, label = letters[1:3])), xlab = "") Regards Duncan Duncan Mackay Department of Agronomy and Soil Science University of New England Armidale NSW 2351 Email: home: mac...@northnet.com.au -Original Message- From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of Ivan Calandra Sent: Thursday, 17 March 2016 23:26 To: R list Cc: Anne CANER Subject: Re: [R] plot numeric vs character So it looks like there is no better "base" solution than Petr's code...

Re: [R] plot numeric vs character
Hi I am not an expert but it probably results from covenience plot.factor method which calls boxplot when used for or factor data. See graphics:::plot.factor graphics:::boxplot.default I belive that you can do something with ggplot like (untested) p <-ggplot(mydf, aes(x=let, y=num)) p+geom_point() p+geom_jitter() or change plot.factor method, which is beyound my level. I considered dotchart but it is used for differnt data structure.
