Hola, Otra alternativia que tienes, por la complejidad de la ecuación que la tienes expresada como un sumatorio (sin desarrollar) es utilizar "R" unido al paquete de matemática simbólica "Yacas", mediante "RYacas": https://cran.r-project.org/web/packages/Ryacas/index.html Saludos, Carlos Ortega

There was no attachment so we cannot tell if your problem is an R problem that is appropriate for the R-help list or if it is a RStudio issue that should go to their help forum. The R-help list is very fussy about what kinds of attachments that it well accept. It usually is best to just copy

Re: [R] Control of x-axis variable ordering in ggplot

You have two problems: * geom_line() always draws from right-to-left * you're defining colour outside of the plot in a very non-ggplot2 way. Here's how I'd do it: library(ggplot2) data <- data.frame( x = rep(1:4, each = 25), y = rep(1:25, times = 4), g = rep(1:4, each = 25) ) data$x <-

Re: [R] Control of x-axis variable ordering in ggplot

Hi, are you trying to do the same thing with ggplot as with lattice? In this case, your solution looks probably like this: ggplot(data, aes(x, y, group = g)) + geom_path(aes(colour = g)) If you haven’t done so yet, I strongly recommend reading through the ggplot2 documentation:
