[R] How to correct documentation?

Hi, I used "?mtcars" to read the documentation for the dataset. I found a mistake in how unit is listed, namely, that for the variable "wt," the unit should be listed as "1000 lb," not "lb/1000." However, I don't know whom to contact exactly for the correction. Please point me to the right plac

Don't use html formatted emails. The r-help server strips the html formatting leaving us the the mess you see below. You don't need any loops: > aa <- matrix(1:9, 3, 3) > bb <- aa * 10 > cc <- bb * 10 > x <- as.matrix(expand.grid(k=1:3, j=1:3, c=1:3, r=1:3)) > str(x) int [1:81, 1:4] 1 2 3 1 2

Re: [R] ggplot: combining geom's in function

Hi Thanks for the suggestion. Unfortunately, the qplot function would work nicely if only I did not need to combine its output with other geom called before... A simple example using the data previously described: ggplot(data, aes(x,y,group=g)) + geom_blank() + qplot(x=x,y=y,data=data,group

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: http://doc

I do not understand exactly what you're looking for: "Any way to rewrite the code.." is pretty vague. Here is _an_ answer, which may completely miss what you mean, followed by some comments. y <- 1 f1 <- function(x=y) { cat("y =", x, "\n") } f2 <- function() { y <- 2 f1() } f3 <- functio

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 <- dat
