array subsetting of S4 object that inherits from "array"
...ountered it before. I tested it on R.2.7.0 and confirmed that class(x[1]) returned "numeric". In my case, the desired behavior is for array subsetting in all cases to return primitive data structures, so if there is a way to override the new behavior I would opt for that.

trellis plot
...panel.loess(x,y,span=.15) } ) However, this gives me only a single loess curve (collapsed across groups) whereas I would like one curve for each group (just as I get one color for each set of points from the panel.superpose).

"[" operator and indexing ambiguity
...rit from the "array" class directly? (See below for a snippet from the EBImage package which suggests that it cannot).

reverse array indexing
...array: tmp <- array(1:8, c(2,2,2)) is there a function out there that, given a one-dimensional array index, will return the separate indices for each array dimension? for instance, tmp[8] is equivalent to tmp[2,2,2]. I'd like to derive the vector (2,2,2) from the index 8. thanks, Brad Buchsbaum

label tickmarks in persp()-plot
Dear R-users, is there a way to label the tickmarks other than persp does it? I didn't find anything on that in the archive. To plot the surface with equi-distant tickmarks, I assigned x<-c(1:6) y<-x persp(x,y,z,....) Instead of labels 1 to 6, I need something like 0.05, 0.1,10,15,100,1000. Any hint and help appreciated, Nina

multivariate simulation
To whom it may concern, I try to simulate a non-normal multivariate distribution. The MASS package allows by mean of "mvrnorm" command to perform a multivariate normal simulation. Is there an equivalent command for an arbitrary multivariate distribution available in the R-language? Thank you in advance.

nested versus crossed random effects

I guess I'm confused as to the practical difference between coding "Trial" as replicates of certain factorial combinations or coding "Trial" without respect to other variables in the design.

RSVGDev, lattice plots
...9;m hoping to use the SVG graphics device for exporting R plots to a java application. It works well for most basic plots from the "plot" command, but does not do so well with xyplot from the lattice package. Something like: xyplot(y ~ x | f) should demonstrate the problem. thanks, Brad Buchsbaum
