Are there parameters that would allow adjusting y axis labels in lattice plots? E.g in the following simple example require(lattice) xyplot(rnorm(10) ~ 1:10, scales=list(alternating=2)) it would be nice to have the y axis labels adjusted to the right or at the decimal point instead of left adjustment.

Hello Since I changed my X11 settings to a Xinerama setup, calls to x11() result in windows with a width half the size of the one specified by the corresponding parameter. Furthermore, x axis labels are overlapping. Other devices (e.g. pdf()), are not affected by these distortions. Did anybody have the same problem, and if so, how did you solve it? ( I'm using openSUSE 10.3 on a x86

Dear R users I'm looking for algorithms that assist in spreading out crowded labels, e.g. labels of points in a scatter plot, in order to obtain a nicer visual appearance and better legibility. I'm probably just stuck because I didn't find the right key words for a successful search on the R websites or in the mailing list archives. Any hints are appreciated. Thomas Zumbrunn

This results in wrongly proportioned plots, wrongly positioned text etc. Other devices are not affected. I already asked

Dear R users I have problems horizontally aligning labels in keys of lattice plots when the labels make use of plotmath. Here's a self-contained example: dat <- data.frame(x = rnorm(10), y = rnorm(10), z = factor(rep(c("a", "b"), each = 5))) xyplot(y ~ x, dat, groups = z, auto.key = list(columns = 2, text =

I'm trying to use a lattice function within a function and have problems passing the "groups" argument properly. Let's say I have a data frame d <- data.frame(x = rnorm(100), y = c("a", "b")) and want to plot variable x in a densityplot, grouped by the variable y, then I would do something like densityplot(~ x, d, groups = y) If however I wanted to

Greetings, R-Helpers: I am trying to build a package on WinXP, something that I have done before, but infrequently, and have recently updated both the Rtools and the version of R being used. My test case fails after successfully creating the compiled html files with this error message: . . . Created c:\DOCUME~1\CHARLE~1\LOCALS~1\Temp\Rbuild142865646\March18\chm\March18.chm, 41,494

Dear List, just out of pure curiosity: is it possible to define a function via 'substitute()' such that the function's formal arguments are specified by a "wildcard" that is substituted when the expression is evaluated? Simple example: x.args <- formals("data.frame") x.body <- expression( out <- myArg + 100, return(out) ) expr <-

Hi all, I'm trying to process all files with a certain extension "*.ext" in a directory like this: > R --slave --args /my/dir < dir_plot.r where I then I want to do something like: myarg <- commandArgs() inputdir <- myarg[length(myarg)] print(inputdir) "for file with extension "*.ext in inputdir" do data = process.data(file) outfile =

This is was something like a request for your comments, thoughts on the topic... Many of you will know that the "..." (aka \dots) argument is very useful for passing ``further graphical parameters'', but can be a pain when itself is passed to too many plotting functions inside your own function. An artificial example being myplot <- function(x,y, ...) { plot(0:1, 0:1,

Dear R-users, I am translating a S script into R and having some troubles with the match function. This function appears to work with vector and data.frame in S, but not in R, e.g.: a <- rep((1:4), each = 10) b <- rep((1:10), times = 4) mydf <- data.frame(a,b) myarg <- mydf[1,] match(myarg, mydf) # S returns 1 but R returns NA NA I guess one could use match(interaction(myarg),

Using R 2.4, the following fails: setClass("testc", representation(a="ANY")) makeC <- function(myarg) new("testc", a=myarg) makeC() -> Error in initialize(value, ...) : argument "myarg" is missing, with no default On the other hand, this is OK: f <- function(a) g(b=a) g <- function(b) if(missing(b)) "missing" else "valid

When I write a share comment with some chara= cters, there are not translated properly inside smb.conf file. = When I read my smb.conf file, I noticed that for example a cp1252 characte= r like (0xC1) has been changed onto an ISO8859-15 character

Hi everyone I'd like to flip grobs (grid graphical objects) along an axis, e.g. flip grobs horizontally or vertically. I couldn't find any hints, neither in the documentation nor by searching the web. Does anybody know how to achieve this? Cheers /thomas

Frequently we have a print method, say print.myclass, that has a variety of arguments. If in the .Rd file I say \usage{ \method{print}{myclass}(x, myarg) } I get a warning when running R CMD chk: * checking generic/method consistency ... WARNING print: function(x, ...) print.myclass: function(x, myarg) What is the proper way to handle this? Thanks -- Frank E Harrell Jr

Below is an example of output that changed as a result of r64970. I did not see any NEWS item suggesting this change is expected. Note that the example is contrived and I don't have a use case for it. I stumbled across it when playing with recent changes in R relating to duplication. Does the example use undefined syntax? ----- fn1 <- function(mylist) { fn1a <- function()

I have been converting to utf8 from latin1, and this gives me problems, some solved, but here is one unsolved: In my .Rd files, I have included '\encoding{UTF-8}' at the top. Despite this, the HTML help pages contains 'content="text/html; charset=iso-8859-1"', and my name is mangled. What can I do about this? I'm on Ubuntu (latest), R-2.3.1 Thanks, G?ran

I tried to emulate the axis interval calculation behaviour of the traditional graphics system (with par(xaxs="i")) in lattice but couldn't find a flexible solution. Let's say a have a simple xyplot: x <- seq(0, 1, 0.01) xyplot(x^2 ~ x, type="l") I want to restrict the plotting region to the data range _and_ have axis labels over the full data range like this:
