similar to: axis.POSIXct and axis.Date fail for reversed axes

Hello, I would like to suggest the following change to image.default in src\library\graphics\R\image.R: 98c98 < plot(NA, NA, xlim = xlim, ylim = ylim, type = "n", xaxs = xaxs, --- > plot(x[1], y[1], xlim = xlim, ylim = ylim, type = "n", xaxs = xaxs, This provides all the support of axis.POSIXt that plot.default gives, currently the default new plot in

Hi everybody, I want an x-axis which has xlim=c(max, min) rather than xlim=c(min, max) in order to reflect the type of the process (cooling): library(lattice) myprepanel <- function(x,y,...) list(xlim=rev(range(x))) x <- rep(1:10, 100) z <- factor(sample(10, 1000, T)) y <- rnorm(1000, x, as.numeric(z)) xyplot(y~x|z, scales=list(x="free"), prepanel=myprepanel) This works

Hi, Given that cdplot() is used to produce the conditional density of a categorical y along a numerical x, it seems natural that it could be used with a date or time x (such as 'POSIXct'). Is this desirable? If so, I've created a patch that would allow this, by coercing the POSIXct x variable to produce the density, but use the original POSIXct x to draw the x axis. Index:

I noticed some undocumented and inconsistent behavior in device_Raster when a plot is produced with reflected axes such as: image(volcano, xlim = c(1,0), useRaster = TRUE) image(volcano, ylim = c(1,0), useRaster = TRUE) The `pdf` device will perform horizontal and vertical reflections, while `quartz` will ignore the transformations when plotting to the screen, but when plotting to a

Hello, I have found that in smoothScatter it is not possible to reverse the axes plotted (R version 2.9.0) .   It appears that this arises from the hard coding of xlim and ylim in smoothscatter.R in the lines : x <- x[ xlim[1] <= x[,1] & x[,1] <=xlim[2], ]   (line  number 25) and x <- x[ ylim[1] <= x[,2] & x[,2] <= ylim[2], ]  (line number 31) This results in a x

I have encountered the following behaviour in lattice in 2.6.1 (and 2.4.0) which differs depending upon the type you use. I believe the numeric behaviour to be correct, and the POSIXct behaviour to be in error. When the x data and x axis in a lattice graph are POSIXct, and when using scales$x$at and scales$x$labels to add custom labels: If the first visible at value is not the first

Dear R users, I would like to reverse the axes on some xy plots (for example to set the origin at the top left rather than the bottom left). I had planned to use something of the following form: plot(y=y<-c(20,4,5,6),x=x<-c(10,20,30,40),ylim=rev(range(y))) ie reversing ylim to reverse the y axis. This works fine however I also want to use the parameter asp=1 to ensure that equal

I'd like to make a plot with the axes drawn at the values of xlim and ylim. The default plot draws the axes slightly outside these values. I have been experimenting with the par(mgp) setting, but specifying par(mgp=c(2,0,-1)) gives me "invalid value specified for graphics parameter "mgp".". A more complicated mathod that almost seems to work is doing the plot with

Hy all, I'm plotting graphs using plot() function, they are on X axes POSIX dates: "POSIXt" "oldClass" "POSIXct" "POSIXlt" I can't figure out why sometimes it prints the month and days and sometimes it prints the unix timestamp. It appens usually when the xlim is short like only some days. xlim is settled as a POSIXt like this "2006-12-30

Full_Name: Bob O'Hara Version: 2.6.0 OS: Windows XP Submission from: (NULL) (88.112.20.250) Using horizontal=TRUE with boxplot() confuses it as to what is an x- or y-axis. At least, xlim= and ylim= are the wrong way round, log="x" (or "y") and xaxt= work as expected, I haven't looked at anything else. Some code to see if you can reproduce the bug (or discover

Hi Folks, I've been digging for the solution to this for several hours now. If there is a solution, it must be one of the worst "needle-in-a-haystack" examples in R documentation! Essentially, I want to make an x-y plot in which the X-axis really is the X-axis (i.e. its vertical position is at y=0), and the Y-axis really is the Y-axis (i.e. its horizontal position is at x=0).

[This is an edited version of an email that I sent to Paul Murrell. He was in favour of the idea (although he noted the obstacles that: it could make par() longer; somebody has to implement it) and suggested I submit this as a wishlist item.] Do you think it would be worth adding options to plot commands to reverse axes? Here is a simple example: > x <- 1:12 > plot(x) Whereas if I

hello, i try to plot 3 graphs which have the same x.axis underneath each other. i'd like the plots to be aligned without margings between the boxes and draw a single x axis beneath the lowest plot. i managed to get the alignment by setting par(mar), but the middle box is stretched and i cant't figure out how to get around this. par(pin) was my guess, but this doesn't do the job

Dear plotting wizards, when plotting in R, the actual lengths of the axes are slightly greater than the ranges of the x/y variables or xlim/ylim values. how do I control the amount by which the axes are enlarged? Is there a way to enforce that the lengths of the axes equal xlim/ylim? example: plot(0:100,0:100,pch="+") it can be observed, that the x- and y-axis join at approx.

Hi! If I'm plotting 2 variables with the same units (i.e. wing length of 2 species), how can I force that X and Y axes have the same size for length unit? For example, if X ranges from 0 to 10 and Y ranges from 10 to 30, I want Y axis to be twice as long as X axis. I know I can just put xlim and ylim from 0 to 30, i.e., plot(runif(10,0,10),runif(10,10,30),xlim=c(0,30),ylim=c(0,30)) but this

Hi, I would like to tell R what increments to put the tick marks on an axes, e.g. xlim=seq(-5,5,1). I know that will not work. xlim will only except the beginning and end of the range for the axes. Thanks, Keith jones

Dear R-help, I am creating a two lattice plots (a densityplot() and xyplot()) that have the same x-axes and then 'printing' them onto the same page, one above the other (see end of email for an example to generate the graph). With different labels on the y-axis for each plot the left spacing is different, and the x-axes don't align vertically. Although I can manually modify the

Hi, I am trying to put on one plot two different logarithmic scales, using the bottom and top X-axes. Below there is an example of what I am trying to achieve, using axTicks() -- and fails. I already spent few hours on that, and cannot figure out from ?par and ?axTicks what I am doing wrong. Example follows: ############################################################ #### Data x <-

Hi, Just to signal that when I want to plot POSIXct variable on x using format within plot(), I get what I want on the plot but with a number of warnings: > plot(y~x,format="%y-%m") Warning messages: 1: "format" is not a graphical parameter in: plot.window(xlim, ylim, log, asp, ...) 2: "format" is not a graphical parameter in: plot.xy(xy, type, pch, lty,
