Because there are only 4 locations for the points to go, it will help to jitter the points so they do not all get overplotted. This is done using the ggplot(df) … Predicted probabilities for logistic regression models using R and ggplot2 - predicted-probabilities-for-logistic-regression.R The easiest, after you have your data in two separate data.frames would be to merge them by position: Then you can call ggplot on this data.frame without warnings: In future you could directly avoid the creation of two separate data.frames which you have to merge later. Note #> Null deviance: 43.860 on 31 degrees of freedom #> --- #> (Intercept) am #> To see how the predictions differ for linear and logistic regressions, try drawing both trend lines side by side.
