How to draw lines between multiple x and y positions in a data file

Question

I would like to know how in R I could plot the lines between the x and y points (which ultimately draw multiple rectangles) using the data source supplied.

Obviously, I'm an R newbie.

Thanks. T

...here's a sample of the data im working with;

Please read your data as a `csv` file and post its `dput`. See more [here](https://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example). — NelsonGon, Jun 12 '19 at 06:29

You can use geom_segment from ggplot2. An example:

library(ggplot2)

df <- data.frame(x = c(1,2), y = c(1,1), xend = c(2,1), yend = c(2,1))
ggplot(df) + geom_segment(aes(x = x, y = y, xend = xend, yend = yend))

This draws two lines. One from P(1/1) to P(2/2), the other from P(1/1) to P(2/1).

Hope this helps.
