how can I overlay two or more graphs without the axes boundaries also appearing overlaid on the figure?
a = rnorm(1000) b = runif(1000) plot(a, type = "l") par(new = T) plot(b, type = "l", col = "blue", xlab = "", ylab = "") #os eixos de y ficam sobrepostos
If your goal is the same as the example, one solution is to use
a = rnorm(1000) b = runif(1000) matplot(cbind(a, b), type = 'l')
It is also possible to do with
library(ggplot2) ggplot(data = data.frame(a = a, b = b, x = 1:1000)) + geom_line(aes(x = x, y = a, colour = 'a')) + geom_line(aes(x = x, y = b, colour = 'b'))
