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...

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...

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...

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...

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...

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...

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...

While preparing a function that contained non-ASCII characters for inclusion into a package, I replaced all non-ASCII characters with UTF-8 escape sequences (using \uxxxx) in order to make the package portable (and adhere to "R CMD check...

Maybe my question was not concise enough. I was referring to objects created with the "package "grid" (also called "grobs"), not to the function "grid" from package "graphics". For instance, let's say I have a polygon createad with grid...

My question was answered off list by Paul Murrell, author of 'grid'. Here's am excerpt of our email exchange for the records of R-help. ======== Paul Murrell ======== In some special cases, you would be able to "flip" shapes. If...

Dear all I'm using lmer() to obtain variance component estimates for the estimation of intraclass correlation coefficients (ICCs). However, I'm struggling with the specification of a proper model. I'd like to illustrate the problem with an example...
