Re: [R] Very slow in processing the equation in the scatter plot ggplot

Hi, One problem is that you are printing the regression equation multiple times. Compare: system.time({ + p2 - p1 + annotate(x = -0.1, y = 0.5, geom=text, label = lm_eqn(mydata), parse = TRUE) + print(p2) + }) user system elapsed 0.930 0.006 0.976 system.time({ + p3 - p1 +
