similar to: lattice log scale labels.

Do the "at" and "labels" components of the "scales" list argument to xyplot not do what you want?

I have a problem with lattice log scales that I could use some help with. I'm trying to print log y-axis scales without exponents in the labels. A similar thread with Deepayan' recommendation is here: http://tolstoy.newcastle.edu.au/R/e11/help/10/09/9865.html. For example, this code using xyplot produces a logged y-axis but the labels (e.g. "10^1.2") are not very

Hi all, How can I decrease the number of ticks on the y-axis in a lattice levelplot()? I have as many ticks displayed on the y-axis as I have columns of data (1000 columns), how can I decrease this amount of ticks, while still properly displaying all the data? Note that I get my data from a matrix object, in which the z-values of the levelplot are the actual values in the matrix, whereas the

Hi, I'm trying to use Grid plots and would like to have an X axis that represents dates. I have several years of data so I would like to be able to have labeled tick marks only intermittently (not one per date). I can transform the initial data from a date time string into POSIXlt or POSIXct, or Date objects. The issue is that when I try to layout the plot using: dev.off() pushViewport(

In the example R script below, horizontal gray gridlines are drawn at y coordinates where the points are drawn with the code: panel.abline(h=y, v=xScale, col.line="gray") How do I change this so that the horizontal gray gridlines are drawn at y coordinates where the y labels are drawn? The challenge is that each panel has different y-ranges (in my real example the y-ranges and

I'm trying to set up a lattice plot with two y-axes for each panel. (Yes, I know that multiple y-axes are generally a bad idea; the graph is for someone else and they want it that way.) I've used a custom yscale.component in xyplot to achieve this: myyscale.component <- function(...) { ans <- yscale.components.default(...) ans$right <- ans$left foo <-

Hi R Users, I'm using following data/code (data is also attached) to produce a stacked barplot. *I need help with changing legend boxes, currently I'm using "rectangles=TRUE". Is it possible to get small squares instead -- may be with a small gap between colored squares.* Currently there is no gap between the colored rectangles. # Sample Data: Names Col1 Col2 Col3 Row1 -20 40

I need to make a fairly complex animated graphic and decided to use grid for it. A very simple example of what I need: ##============================================================================== library(grid) grid.newpage() pushViewport(plotViewport()) pushViewport(viewport(xscale = extendrange(c(0, 100)), yscale = extendrange(c(0, 100)))) grid.xaxis() grid.yaxis()

r-friends-- I am trying to make a lattice plot with a single label at 0.05. A reference line at y=0.05 as well... This is what I have so far. The label reads 0.0 and there is a grid instead of a single reference line. Can someone help please? Troy x<-18:35 (pv<-1/(x-17)) xydf<-data.frame(x, pv) print(xyplot(pv~x, data=xydf, type=c('p', 'g'), ylim=c(0,1),

Thanks Jeff, I attached a file with the program to my earlier email because the posting guide seemed to imply that non-binary attachments would work. But I see that the file was stripped off. I installed the program file on a web site, but when I downloaded it, the line breaks were stripped out. So I've included the program below: ------------------------------------------------------- #

Dear list, I try to set a secondary y-axis in a lattice xyplot. This works. However, I am unable to set a proper legend/key together with the 2nd y-axis under general xyplot procedures. See example below. The combination of the par.settings with simpleTheme and other settings seems to go wrong. I couldn't find a solution from previous topics. Any suggestions? thanks in advance!

Hi, I am trying to run the command "forward.sel.par," however I receive the error message: "Error: could not find function 'simpleRDA2'." I have the vegan library loaded. The documentation on "varpart" has not helped me to understand why I cannot call this function. Maybe I am missing something obvious because I am still an 'R' novice. Below is a

After a long and winding road (sorry but I'm a novice) I get to a final result which is quite close to what I need; nevertheless I would like to tweak a little further the xyplot so that I can get ***for each single panel defined by variable z*** a finer control over: -the x and y the limits: I would like to be the same for both axes; -the number of thick marks: again I would like to be same

Am just feeling my way into the grid library, and cannot figure out how to define the plot limits. 3/5 of the example polygons below plot in the default 0-1 range viewport. But when I try to redefine the viewport the polygons plot in the same places. I also get the same result without employing push/pop. (As you can see from the scale I'm trying to introduce, I want to plot map polygons.)

Dear Rxperts, How do I hide the top and right axes in multiple panel plots? A couple of examples are provided below.. Would highly appreciate appreciate your assistance.. #Example 1 library(latticeExtra) xyplot((1:200)/20 ~ (1:200)/20, type = c("p", "g"), scales = list(x = list(log = 2,alternating=0), y = list(log = 10,alternating=0)), xscale.components =

When I use grid.rect to print a multi-coloured grid, it is incredibly slow compared to a single colour grid, or even a two colour grid. I've set out some simplified examples below. This is something I run literally thousands of times a day, so I would greatly appreciate any hints on how I might improve the speed??? library(grid) pushViewport(viewport( width = unit(100,

For a non-log-scaled y-axis, I was able to change the appearance of the y tick labels in an xyplot by using a custom function for yscale.components. However I couldn't get that approach to work for when scales=list(y=list(log=TRUE)). What I'm trying to do is make the y-tick labels show up as something like (10, 100, 1000, etc.) rather than the default (10^1.0, 10^2.0, 10^3.0, etc.).

I have a stupid problem that is currently driving me crazy... Let us suppose that I want to draw a big red square in the middle of my current device (say X11) I tried the following code : pushViewport(viewport(xscale=c(0,1), yscale=c(0,1)), just=c("center", "center")) vp1 <- viewport(x=unit(0.5, "native"), y=unit(0.5, "native"), width=unit(0.4,
