dear r-helpers, it seems the colors in an automatically generated lattice legend recycle after the 8th color, even when the user has set e.g. superpose.symbol$col to be longer than 8. the following example will illustrate what i mean: z <- data.frame(x=rep(letters[1:15], each=4), y=rnorm(60), groups=rep(LETTERS[1:3], 20)) library(nlme) library(lattice) plot(groupedData(y ~ x |

Dear List Members I'm using R to create a trellis plot using the library of Pinheiro & Bates (trellis graph for grouped data). Here is my question: How can I change the format of the axis (x or y) in terms of the number decimal points that should appear on the plot? In other words, I have that for a set of plots in the y-axis the values appear as 0.2,0.3, etc and for another set they

Hi folks. It looks like it's stirred some discussion ultimately resulting/concluding that this phenomena is a possible bug either in the lattice package or in R 1.9.0/1.9.1 itself. So, I'll stay tuned, so to speak, for either an update in the lattice package or R as it seems that that's where the bug may lie. FYI, the resulting plot, (e.g., plot(1~1)), worked as it should either

Dear List members, its me again, fighting with lattice graphics. I am trying to plot a world map, add some points on different locations with different colors and add a legend, but did not succeed yet with the legend. Here is my code: library(fields) # Data for demonstration data_x = c(0,50,60) data_y = c(0,0,0) cols???= c(1,2,3) data(world.dat) #print map all=xyplot(world.dat$y? ~

Dear List, I have been using R to create an xyplot using the panel function within lattice libraries. This plot is based on the data supplied in R named 'Oats'. The graph represents oat yield by nitro level with an overlay of each variety of oats for each nitro level. I have three questions regarding this graph: 1) I cannot seem to specify the type of symbol used by the plot, even though

Hi: I am using the following command: xyplot(dat6$CO3*1e6 ~ dat6$irradiance, data=dat6, group=ref, xlab=list(label=expression(paste("Irradiance (", mu, "mol photons", m^"-2", " ", s^"-1", ")")), cex=1.3), ylab=list(label=expression(paste("Carbonate concentration (x ", 10^"6", " ", kg^"-1",

Hello, My colleagues and I use lattice for a variety of different purposes, and we came across a couple issues involving legend.R and update.trellis.R: 1. When using xyplot, the shapes in the plots are able to have borders and fill colours, but not so in the legend. I created a short script to isolate the problem (see legend-icons.R and Nofill.png). After some tracing through the source code,

Hi listers, I want to make lattice plots xyplots with the indication of legends inside each panel with only the points and the lines actually ploted inside each given panel according to the group(ing) factor. The code below shows what I have achieved so far and I hope will make clear what I want to have. It seems to me that my solution is a very "dirty hack" and there certainly is

I have some geospatial data where two layers are thematic and the third is a percentage, so the maps need to have different themes. thumbDf <- as( stack( thumb), "SpatialGridDataFrame") names(thumbDf at data) <- c("pri", "sec", "pct") thumbDf at data$pri <- factor(thumbDf at data$pri, levels=c(0:8), labels= names( peelClasses)) thumbDf at

Hello! I have a question about my lattice barchart that I am trying to build in Section 3 below. I can't figure out a couple of things: 1. When I look at the dataframe "test" that I am trying to plot, it looks right to me (the group "Total" is always the first out of 5). However, in the chart it is the last. Why? 2. How can I make sure the value labels (on y) are not

Hi all, is it possible to dynamically add key items to an already existing key, belonging to a lattice xyplot? This is what I do: I make an xyplot with an initial key. Later on, I want to extend this key with more items, as more lines are added to the plot (lines are added using trellis.focus("panel")). I guess I need some function to access the key panel in order to extend it,

Hi List, Am trying to customize a legend in trellis: Draws 2x5 lines in 5 colors and 2 linetypes. I would like to add two more items to the legend showing the key for the line types above the colored legend. Any suggestions welcome - thanks Herry ############################# #Following example code: library(gregmisc) trellis.device(bg="white") i1=0 i2=-1.89767506 i3=-1.17087085

I suspect there is a simple solution to this problem, but have been unable to find it. Below is some code that I have run to create 3 lattice graphs. I have been asked to change the legend so that the 'No' and dark blue are above "Y" and light blue in the legend to mirror the stacked bars in the graph which feature dark blue above light blue. I have tried changing the data

Hi, I have a set of 4 graphs and I need to add a legend that is shared by those 4 graphs. This is what I tried: >locator(1) # I placed the cursor in the center of the 4 graphs $x [1] 9.299001 $y [1] 226.3201 >legend(9.3,226.3,"and the rest of the legend arguments")# but the legend didn't show. The legend only appears when I place in inside any of the for plots. How

Dear list, I'm writing a long document (thesis) and as much as I would like to use only ggplot2 for the graphics, some features are still a bit undocumented so I often end up choosing either ggplot2, lattice, or base plots (which i know better) depending on the particular graph to produce. With the default settings, this does not make for a consistent look I would like to see

I have recently converted from S-Plus (Dec Alpha) to R (Mandrake 10.0). The differences are subtle but in some cases not easily converted. My Splus Command plotting deck was over 1200 lines and R has simplified this down to 900 lines so far. I do a lot of mapping with polygons and I am trying to figure out how to increase the default size of the fill boxes in the legend call. Splus had a

Dear all I have two questions regarding trellis plots - which I hope you may be able to help me with. Is it possible to place the key in a trellis plot on the panel (instead of beside the panel)? This will cause the same key to be reproduced on each panel. Please see the plot below - here I placed the legend below the plot. I tried moving the key to the function statement, but it did not really

The Lattice auto.key argument has a bug in R.12.2. R version 2.12.2 (2011-02-25) Platform: i386-pc-mingw32/i386 (32-bit) .... other attached packages: [1] lattice_0.19-17 loaded via a namespace (and not attached): [1] grid_2.12.2 If I set up my plot parameters as require(lattice) superpose.line.settings <- trellis.par.get("superpose.line") str(superpose.line.settings)

I have a moderately complex graph with three panels. There are data points plotted, and fitted lines are added using a panel function, which includes "with(alt.data[[which.packet()[1]]]" statements. It all graphs out beautifully, but none of the usual tricks to get the proper legend to plot are working, i.e., using auto.key, key, etc. One message I keep getting is Error in

When I create a lattice/Trellis type graph, I typically write a function that returns the graph, as in do.graph <- function(x, y, ...) { require(lattice) return(xyplot(y~x, ...)) } My question today is this: If I want two graphs on one page, one way of achieving it is to print the objects into defined areas, as in gr1 <- xyplot(rnorm(111) ~ runif(111)) gr2 <-
