[R] lattice: add a marginal histogram on top of the colorkey of a levelplot?

2012-05-29 Thread Andy Bunn
Lattice experts: Can you think of a way to produce a levelplot as below and then add a histogram of the z variable to the top margin of the plot that would sit on top of the color key? x <- seq(pi/4, 5 * pi, length.out = 100) y <- seq(pi/4, 5 * pi, length.out = 100) r <- as.vector(sqrt(outer(

[R] Hmisc::xYplot - text on xaxis

2012-04-26 Thread Andy Bunn
Hello, I'm making a simple plot using xYplot in the Hmisc library and having problems with labeling the values on the x-axis. Using the reproducible example below, how can I have the text (jan, feb,mar, etc.) in place of 1:12. Thanks, AB x <- c(seq(0,0.5,by=0.1),seq(0.5,0,by=-0.1)) ci <- rnor

Apologies for thickness - I'm sure that this operates as documented and with good reason. However... My understanding of arima.sim() is obviously imperfect. In the example below I assume that x1 and x2 are similar white noise processes with a mean of 5 and a standard deviation of 1. I thought x

[R] equal spacing of the polygons in levelplot key (lattice)

2011-11-15 Thread Andy Bunn
Given the example: R> (levs <- quantile(volcano,c(0,0.1,0.5,0.9,0.99,1))) 0% 10% 50% 90% 99% 100% 94 100 124 170 189 195 R> levelplot(volcano,at=levs) How can I make the key categorical with the size of the divisions equally spaced in the key? E.g., five equal size rectangles wit
