How to add Trend Lines in R Using Plotly — R-bloggers

(This article was first published on R – Displayr, and kindly contributed to R-bloggers) 1. Global trend lines One of the simplest methods to identify trends is to fit a ordinary least squares regression model to the data. The model most people are familiar with is the linear model, but you can add other polynomial…
