Ggplot linear fit. This is a linear model fit so I use method lm. The fitted values geom_line data fortify fit aes x mpg y fitted 2 Likes Anantadinath November 8 2017 1043am 9. Looking at a linear fit we see it is poor at the extremes p stat_smooth method lm formula y x size 1 To get a sense of something like the mean miles per gallon at every level of horsepower we can instead use a locally weighted regression.
I used fill to make the ribbons the same color as the lines. If TRUE the fit spans the. Other than this the stat_smooth command will only put one quadratic line while I need two quadratic lines for both y1 and y2.
P stat_smooth method loess formula y x. Note that its also possible to indicate the formula as formula y polyx 3 to specify a degree 3 polynomial. Fit1.
