Hi, ?.Machine says that 'double.xmin' is 'the smallest non-zero normalized floating-point number'. On my machine, this is 2.225074e-308. However, 2.225074e-308 / 2 is > 0 and smaller than 2.225074e-308, so double.xmin is...
Dear expeRts, I would like to find out how R computes pbinom(). A grep in the source code reveiled src/library/stats/R/distn.R:146: .External(C_pbinom, q, size, prob, lower.tail, log.p), so 'C_pbinom' refers...
Dear all, How can I get a bold "1000" in the title? I would like to use a variable (as opposed to putting in "1000" directly). library(lattice) N <- 1000 xyplot(0~0, xlab.top=list(label=as.expression(bquote...
Dear expeRts, I would like to create a plotmath-label of the form X_1^\prime. Here is how to *not* do it [not nicely aligned symbols]: plot(0,0,main=expression(italic(X*minute[1]))) plot(0,0,main...
Dear Karl, I get exactly the same warning messages with an Rmpi minimal example (also took me a while to narrow it down). I posted it on R-sig-hpc (more appropriate for these issues I believe), some days ago...
Dear Bill, Thanks a lot for your quick reply, that was exactly what I was looking for. Cheers, Marius William Dunlap <wdunlap at tibco.com> writes: > Does ave() do what you want? > y. <- ave(x$value, x$x1, x$x2...
Hi, Is there a plotmath symbol like LaTeX's \mapsto? I need this comparably often, for example if you want to plot a two-place function in one variable (and thus would like to have ylab="t \mapsto f(t...
Hi, How can I specify the strip text in the xyplot below? I also tried to work with strip.names=c("TRUE","TRUE"), but that did not work. Cheers, Marius library(lattice) x <- 1:10 y <- cbind(1:10,-(1...
Dear expeRts, What are the main differences (advantages/drawbacks) between parallel's makeCluster(, type="PSOCK") and makeCluster(, type="MPI")? According to http://cran.r-project.org/web/views/HighPerformanceComputing.html, MPI has become the 'standard', although the default type of...
okay, I should have remembered... Gabor suggested a pretty nice solution, see: http://r.789695.n4.nabble.com/How-to-create-an-array-of-lists-of-multiple-components-td3167576.html -- View this message in context: http://r.789695.n4.nabble...
Dear expeRts, How can I vertically adjust an axis tick label so that it is nicely aligned with the other labels? library(lattice) xyplot(0~0, xlim=c(0,3), scales=list(x=list(at=c(1,1.1), labels...

Lieber Dirk, das ging ja schnell :-) Vielen Dank und herzliche Gruesse, Marius PS: Habe gerade etwas auf Deiner eindruecklichen Homepage verweilt, sehr spannend! Dirk Eddelbuettel <edd at debian.org> writes: > Marius, > > Wie versprochen, parallel.pdf anbei. > > > > Gruesse, Dirk -- ETH Zurich...
okay, I found something. Not very elegant, but it does the job: ## generate data U <- matrix(runif(4000), ncol=4) ## define panel function for colorizing the panels cols <- c("blue", "black", "black", "blue", "black", "black", "black", "black", "green", "black", "black...
Dear expeRts, how can I decrease the space between the tick marks and the corresponding labels in an splom? See here: library(lattice) U <- matrix(runif(4000), ncol = 8) splom(U, axis.text.cex = 0.2) # => space between the [small...
Dear expeRts, I know I can't paste expressions in the normal way, but I just couldn't figure out how to get the following (I want to paste a character vector to an expression vector) right with bquote() or...
Hi, I would like to have the labels parallel to the axes in my wireframe (lattice) plot. Sure you can use ...xlab=list(label="x-axis",rot=30) and for the z-axis this is easy (as rot=90), but...
Dear Professor Ripley, Thanks for helping. - Yes, cairo.so did not exist - Okay, following the 'first approach', I have to install XQuartz before R and set "export PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig:/usr/local/lib/pkgconfig:/usr/lib...
Hi Duncan, thanks, here is the info: - "alias R" shows alias R='/usr/local/bin/R --no-restore-history --no-save' - I start R in batch mode via "R CMD batch..." Batch mode must be the problem then. If I...
Dear expeRts, ./src/library/base/man/Random.Rd says that L'Ecuyer requires a seed of length 6. ./src/library/parallel/man/RngStream.Rd also mentions this, but only in the text part; In the "Arguments"-part, it says that...
