...hints! Berry PS: I recently read about barcharts in lattice, but by now I'm already used to my function. (And I learned a lot writing it a couple of years ago). # Function horiz.hist <- function(Data, breaks="Sturges", col="transparent", las=1, ylim=range(HBreaks), labelat=pretty(ylim), labels=labelat, border=par("fg"), ... ) {a <- hist(Data, plot=FALSE, breaks=breaks) HBreaks <- a$breaks HBreak1 <- a$breaks[1] hpos <<- function(Pos) (Pos-HBreak1)*(length(HBreaks)-1)/ diff(range(HBreaks)) # Assign a function to the global environment...

Hi! Is there a way to manually costumize the color legend in an spplot() - especially where to draw ticks and labels for the ticks? The reason I'm asking: Usually spplot() automatically divides the data into fitting slices and makes a color legend (also automatically). I want to assign the slices myself and have a fixed scale instead of an automatic/dynamic scale. I think what I want

I recently called plot(x,y) where x was an array of POSIXct timestamps, and was pleasantly surprised that it produced a nice plot right out of the box: z <- as.POSIXct(c("2006-10-26 08:00:00 EDT","2007-10-25 12:00:00 EDT")) x <- seq(z[1],z[2],len=100) y <- 1:100 plot(x,y,type="l") The X axis had nice labels, one tick mark every other month.
