Connecting each column for each row in r ggplot2 scatter plot : <p>I have three columns: "original", "pos1", "pos2". Each row is an individual. I want to create a scatterplot where "original" is on the x-axis, and pos1 and pos2 values are on the y-axis. So each original will have a pos1 dot and a pos2 dot. I can create two different colors to distinguish pos1 and pos2 dots. But what I want is to add a line between pos1 and pos2 for each individual. If I have 100 individual, there will be 100 short lines, connecting each pos1 and pos2. Is there any way I can do this in ggplot?</p>

<p>Thank you! </p>
