Plot Histogram with Points Instead of Bars

Question

Here is a question for R-users. I am interested in drawing a histogram with points stacked up, instead of a bar. For example if the data is (1,1,2,1,2,3,3,3,4,4), then I would like to see three points stacked up at 1, 2 points stacked up at 2 and so on. What is the best way to do this in R?

Answer 1

You can do this yourself pretty quickly:

x <- c(1,1,2,1,2,3,3,3,4,4)
plot(sort(x), sequence(table(x)))

Answer 2

The simplest answer I know is this:

x <- c(1,1,2,1,2,3,3,3,4,4)
stripchart(x,method="stack",at=0)

It's better than Jonathan Chang's suggestion because stripchart does proper stacking of points.
