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 <-
Hi,
I want to thank Jeff, Dennis, c06n, and Hadley for their replies and
explanations. As you probably guessed, I am fairly new to ggplot am
trying to loose my lattice reflex while transitioning to ggplot.
Thank for the link to the ggplot external documentation.

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:
The ggplot function has no display behaviour. You have to couple it with a geom
function to define how the data will be displayed. Read ?geom_line and
?geom_poly.

Hi,
Given a certain data.frame, the lattice xyplot function will plot the
data as.is and join the data point in the order of the data frame. It is
my (probably flawed) understanding that, using the same data frame,
ggplot orders the data by increasing order of the x-axis variable. Can
