Re: [R] add a curve that fits the highest values on the plot.

Hi Nanami, I am not sure exactly what you mean by "fits the peaks"...are any of these plots what you want? x <- 1:20 y <- c(19.4, 17.9, 8.1, 11.3, 7.8, 8, 5, 1.7, 3.9, 5.4, 7.5, 5.4, 4.7, 5, 4.9, 3.5, 2.9, 2.4, 1.4, 1.7) ## Find peaks index <- which(c(NA, diff(sign(diff(y == -2) dev.new() la

[R] add a curve that fits the highest values on the plot.

Hi everyone, I am given two vectors - for example - x= c(0:20) > x [1] 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 and > y [1] 19.4 17.9 8.1 11.3 7.8 8.0 5.0 1.7 3.9 5.4 7.5 5.4 4.7 5.0 4.9 [16] 3.5 2.9 2.4 1.4 1.7 > plot(x,y,xlim=range(x),ylim=range(y))
