[R] about xyplot in lattice

Hi all, I am using xyplot (lattice) to generate a figure like Figure 4.18 in MASS4, but I have the following two questions (1) how to change the font of x(y)lab? (2) how to plot the panels for each level of the conditional variable (a factor in my data set) in the order as occurred in the

[R] how to test this

Dear there, I am wondering how to test whether a simple linear regression model (e.g. y=1.05x) is significantly different from a 1 to 1 line (i.e. y=x). Thanks. Regards, Jin [[alternative HTML version deleted]] __ R-help@stat.math.ethz.ch

[R] a simple question

Dear All, I need to separate one column which is in a format like, can_region, into two columns like, can, and region. Do we have a function in R to do this? Thanks. Regards, Jin [[alternative HTML version deleted]] __

[R] How to correct this

Hi there, I tried to add a few circles on an existing figure using the following codes grid.circle(x=0.5, y=0.5, r=0.1, draw=TRUE, gp=gpar(col=5)) grid.circle(x=0.5, y=0.5, r=0.3, draw=TRUE, gp=gpar(col=5)) grid.circle(x=0.5, y=0.5, r=0.5, draw=TRUE, gp=gpar(col=5)) points(0.5, 0.5,

Hi there, I would like to add a few circles to the following image: x-seq(0,1,0.2) y-x pred-matrix(c(0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.7, 0.7, 0.7, 0.7, 0.5, 0.5, 0.7, 0.9, 0.9, 0.7, 0.5, 0.5, 0.7, 0.9, 0.9, 0.7, 0.5, 0.5, 0.7, 0.7, 0.7, 0.7, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5), 6, 6) image(x,

RE: [R] How to remove x, y labels from a plot

Hi Arne, It works. It produced what I wanted. y-rnorm(1000, 2, 0) plot(density(y), ylab=Abundance of species, xlab=Environmental gradient, main= , lty=2, col=4, xaxt=n, yaxt=n) Thanks, Arne. And also thanks to other responses. Regards, Jin -Original Message- From: Arne Henningsen

[R] How to plot this

Hi there, I produced a plot using the following codes: y-rnorm(1000, 2, 0) x0-c(0, 0) y0-c(0, 0) y1-c(0, 1) x1-c(0, 4) plot(density(y), ylab=Abundance of species, xlab=Environmental gradient, main= , xlim=c(0, 4), ylim=c(0, 1), lty=2, col=4, xaxt=n, yaxt=n, frame.plot=F)
