How to create Needles chart in R?

Question

I am trying to make a chart of Needles suggested in the Matter of Non-parametric Methods in the study of Histograms.

I found a command called rug(), but it seems that the idea is not that.

Answer 1

If you mean the Needle Plot, that is, plot the variables as sliders coming out of the zero (or minimum) axis, just put the parameter type = h in the plot.

For example:

with(economics, plot(date, unemploy, type="h"))

As you mentioned histogram, you might want to see the points of a single variable along a line. For this you can use the dotplot of lattice.

The dotplot plot the points along a line:

set.seed(1)
y = rnorm(100)
library(lattice)
dotplot(y)

You can complement the dotplot placing the "Needles":

dotplot(y, panel= function(x){
  panel.dotplot(x,factor(1))
  panel.xyplot(x, factor(1),col="black", type="h")
})
