WebR uses pass-by-value so what is sent to the function is a copy of your data.frame. (sort of, passing on some details.) So when you call the function, you need to 1) return the modified data.frame and 2) assign it or you will lose the results. http://sthda.com/english/articles/39-regression-model-diagnostics/161-linear-regression-assumptions-and-diagnostics-in-r-essentials
