Plotting linear regression for multiple predictors using ggplot

[Anil kumar E S]

Hello,

How to plot the multi-variable linear regression line using the ggplot?

I tried adding interaction terms to x value, it doesn't seem to work!

Thank you!

Best regards

Anil

Plotting more than a few variables is quite hard. You could get away plotting a 3D plot (if applicable) and map 4-5th variable to color and shape. But 3D plots are not ideal and currently not supported by ggplot2.

Try playing with `facet_wrap` or `facet_grid` to slice through non-continuous variables.

Cheers,

Roman

Interaction terms transform one model into another model depending on group/level, so really you want to look at multiple lines/graphs with that approach. The advice already given should help you with that. You could also look at whether you need that level of complexity in your model i.e removing variables.
