How to plot one variable in ggplot?

Question

I\'m searching but still can\'t find an answer to a quite simple question - how can we produce a simple dot plot of one variable with ggplot2 in R?

with plot<

Answer 1

Actually, you are not plotting one variable, but two. X-variable is the order of your data. The answer to what you want based on your example is:

library(ggplot2)
ggplot(iris, aes(y = Sepal.Length, x = seq(1, length(iris$Sepal.Length)))) + geom_point()

The answer to your question would be closer to this:

ggplot(iris, aes(x = Sepal.Length)) + geom_dotplot()
