I have a data one 100 individuals containing 3 columns.
- Weight before treatment
- Weight after treatment
As en example you could create a table using this:
Data <- data.frame( ID=seq(1:100), Before=sample(80:100,size=100, replace=TRUE), After=sample(60:100,size=100, replace=TRUE))
How can i produce a graph similiar to the one in the following link:
