Re: [R] Plot multiple columns

2010-06-01 Thread Noah Silverman 
Another thought I had was to use Sweave.

I could, in theory, use Sweave to create a plot only 7 inches high, and
then a summary table 4 inches high below it, all on the same page of a
Latex document.  Could be messy, but might work.

Re: [R] Plot multiple columns

2010-06-01 Thread Noah Silverman 
You are correct,

I initially missed the "as.mcmc" step.  Without it, R doesn't want to
squeeze so many plots onto a page. 

Thanks!

Re: [R] Plot multiple columns

2010-06-01 Thread Dennis Murphy 
Hi:

Ben's example worked for me as follows:

x <- matrix(runif(22000),ncol=22)
library(lattice)
library(coda)
m <- as.mcmc(x)
xyplot(m, layout = c(2, 11))

layout =  uses columns first, then rows...I always forget that :)  It also
has an optional
third argument for pages, which might come in handy here. If you want the
order of the
panels to be reversed, use the additional option as.table = TRUE.

Re: [R] Plot multiple columns

Hi,

I used the term "run", as each iteration of the Gibbs sampler produces
22 variables (coefficients for Beta in a regression model)


The example wont work

Re: [R] Plot multiple columns

2010-06-01 Thread baptiste auguie 
Hi,

You could use melt from the reshape package to create a long format
data.frame. This is more easy to plot with lattice or ggplot2, and you
can then use facetting to arrange several plots on the same page. The
dummy example below produces 10 pages of output with 10 graphs per
page.

library(ggplot2)

dl <- replicate(10, as.data.frame(matrix(rnorm(1e3), ncol=10)), simplify=FALSE)
names(dl) <- paste("column", seq_along(dl), sep="")

# dummy list of data.frames
str(dl)

# a function to plot one data.frame
plotone <- function(d, ...)
  qplot(seq_along(value), value, data=melt(d)) +
  facet_wrap(~variable, scales="free")

# call the function for each data.frame
pl <- llply(dl, plotone)

# print to a file
pdf("test.pdf")
l_ply(pl, print)
dev.off()


HTH,

baptiste

Re: [R] Plot multiple columns

2010-06-01 Thread Ivan Calandra 

Hi,

Try with:
par(mfrow=c(11,2))

It should work better!
Remember that mfrow is an argument of the function par(), not a function 
itself.


One other tip: think about using pdf, ps, png, or SVG devices, I find it 
easier and nicer.
