Dear Ista, Thank you so much for the prompt reply. Yes, using the annotate instead of the geom_text definitely speed up my graph and look much better. Thanks. Best Regards, Janesh Devkota On Mon, Jan 21, 2013 at 3:46 PM, Ista Zahn wrote: > Hi, > > One problem is that you are printing the reg

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
