With 2.7.0 patched (not tested with 2.0.0), I get an error message in a program that ran correctly in R 2.6.2 when the grouping factor of a stripplot contains an Umlaut: I am aware that there are a few locale-changes in R 2.7.0, but I could not easily locate who's at fault Dieter library(lattice) dt = data.frame(x=rnorm(100),y=1:100,levs= as.factor(c("Gru","Gr?")))

How to show panels for factor levels of conditioning variables which do have no values? E.g. there are panels for "Grand Rapids" when they have values: data( barley ) with( barley, dotplot(variety ~ yield | year * site, layout=c(6,2) ) ) There are no panels for "Grand Rapids" when there are no values for "Grand Rapids": my.barley <- subset( barley, ! ( site ==

Hello all, In order to get the desired order of panels within lattice I realized I needed to define my factor levels. I now see how to properly do it (attached code), but: 1. I don't understand why I have to use factor() on a variable that is already a factor, and why levels() alone doesn't work to readjust the level order. 2. I just noticed that if I do use levels(xx$v1), it's

Hi, I am trying to create a dotplot where each panel shows levels vs. responses; the levels are sorted by responses but levels vary from one panel to another. However, I run into problems with controlling the y-limits and y-labels. In particular, suppose I have a data frame rsp <- c(10,2,4,0,2,3) lvl <-

Hello ! I'm struggling again against lattice graprhics. ;) I'm trying to produce a conditionnal xyplot with two conditionning factors (let's say A and B). I want the levels of those factors (A1, A2, etc) to show in the margins of the lattice plot, not in the strips between the panels. A1 A2 A3 plot11 plot12 plot13 B1 plot21 plot22 plot23 B2 I managed to remove the

Dear R-experts, I am trying to fit my model but I couldn't because of this error. here is the error "Error in solve.default(dial(m) -A) : Lapack routine dgesv: system is exactly singular" thank you all. sonam

Dear R-ers, I'm not sure if this is a missing feature, a support request, or stupidity on my part, but nevertheless, its a question. Is it possible to add titles to colorkey legends? As far as I can tell, there is a command to do it for normal "key" legends, but not for "colorkeys". eg it works for a normal key, created through auto.key xyplot(decrease ~ treatment,

Hi all - I'm trying to generate lattice barchart graphs with missing values, and came across the following: This does not run. I would expect it to: library(lattice) D = data.frame(X=1, Y=factor(letters[2], letters[1:2])) barchart(~ X, D, groups=Y) Error in grid.Call.graphics("L_rect", x$x, x$y, x$width, x$height, resolveHJust(x$just, : invalid line type which is simply

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

Hallo R-users, I do not understand how to specify the correct line and symbol types in the legends of a lattice xyplot. This is what I tried, but the line types and symbol in the graph are not seen in the legend. Any help is appreciated. Thanks, Gerrit. library(lattice) s<-rep(1:3,len=10) x<- 1:10 y<- x+s+rnorm(10) d<-data.frame(s,x,y) xyplot(y~x, groups=s,data=d,

Good afternoon, I am working on a plot that requires custom legends to be placed in some panels of the plot; other panels do not contain legends. The problem that I run into is positioning of the legend in individual panels. In particular, the 'x' and 'y' elements of the key-list are ignored by draw.key() when it is called from inside a panel function. As a result, the legend is

I am using R 2.8.1 and lattice to produce xyplots conditioned on two factors. What I would like is to have the scales be free between values of one factor, but some within. Thus, in the example: xyplot(mpg ~ disp | factor(gear) + factor(cyl), mtcars, scales=list(x=list(relation="free"))) rather than having the x scales be free within a gear as well, I want it to be the same for

Hello, I'm not sure this is doable but I'm having trouble running my R script with multithreaded capability. With 16x2.93Ghz CPUs available, only one is running with 100%. Any suggestions? Thanks, Bing My system configuration is: egenera virtual machine running Linux Red Hat Enterprise Linux Server release 5.1 (Tikanga) 16x2.93GHz CUPs 99G memory

I'm not able to create the proper syntax to specify a lattice bwplot() for only one of two conditioning factors. The syntax that produces a box plot of each of the two conditioning factors is: bwplot(quant ~ param | era, data=mg.d, main='Dissolved Magnesium', ylab='Concentration (mg/L)') What I've tried unsuccessfully are: bwplot(quant ~ param |

Dear all, I am encountering a problem with lattice in the current version 0.14-13 with R version 2.4.0 on a Windows XP system. For example, histogram(~voice.part, singer) is not labeling the x labels according to the factor levels of voice.part, which it should do (and has done in former versions of lattice, as far as I remember). In addition, I get the warnings Warning messages: 1:

Hello, I am trying to write a new "top level" Trellis/lattice function. By "top-level", I mean a function like 'xyplot', 'histogram', 'bwplot', etc. These functions all call 'trellis.skeleton', which I am unable to call; an attempt to invoke the function that does so yields the error message: ----- Error in do.call("trellis.skeleton",

Hi: Yesterday, I posted a question regarding how to handle different graphical behavior between two factors in xyplot() [package lattice]. After a public and private reply from Deepayan Sarkar, the problem has been resolved nicely, including the addition of a stacked legend for the two factors in question. The latter requires package latticeExtra. library(lattice) library(latticeExtra) # Test

Dear R graphics gurus, Another question about lattice graphics. This time I would like to plot means and confidence intervals by group factor in a lattice graph. I can not find any working lattice examples. Maybe a custom panel function is the answer, but that is a bit beyond me for now. The individual plots within the lattice graph could look like this: # Example with confidence intervals

Hi, Is there any way to suppress plotting of panels that don't actually contain any information? I have tried using 'drop.unused.levels=TRUE', but there doesn't seem to be any effect. Here is an example: library(lattice) # some fake data: d <- data.frame(x=runif(20), x.class=rep(letters[1:5], each=4), f1=rep(letters[1:2], each=10), f2=rep(letters[10:19], each=2) ) # plot
