Hi. Can anyone suggest a simple way to obtain in R a list of vector coordinates of the following form? The code below is Mathematica. In[5]:= Flatten[Table[{i,j,k},{i,3},{j,4},{k,5}], 2] Out[5]= {{1,1,1},{1,1,2},{1,1,3},{1,1,4},{1,1,5},{1,2,1},{1,2,2},{1,2,3},{1 ,2,4},{1,2, 5},{1,3,1},{1,3,2},{1,3,3},{1,3,4},{1,3,5},{1,4,1},{1,4,2},{1,4,3}, {1,4,

Hi, all. Given an array, I'd like to add elements whose location vectors are permutations of one another. For example, in a 3-dimensional array, I'd add the elements in positions (1,2,3), (1,3,2), (2,1,3), (2,3,1), (3,1,2) and (3,2,1); those in positions (1,2,4), (1,4,2), (2,1,4), (2,4,1), (4,1,2), and (4,2,1); and so on. Elements with repeated positions -- (1,1,2) or (1,4,4), for

Dear all, mydata<-data.frame(x1=c(1,4,6),x2=c(3,1,2),x3=c(2,1,3)) cor(mydata) x1 x2 x3 x1 1.0000000 -0.5960396 0.3973597 x2 -0.5960396 1.0000000 0.5000000 x3 0.3973597 0.5000000 1.0000000 I wonder if it is possible to fill only lower triangle of this correlation matrix? Using 'dist' doesn't seem to be useful as it doesnt allow to convert this table

> library(Kendall) > Kendall(1:3,1:3) WARNING: Error exit, tauk2. IFAULT = 12 <<<<<< tau = 1, 2-sided pvalue =1 I believe Kendall tau is well-defined for this case and the reported value is correct; isn't it a bug to give a warning? (And if, e.g., the pvalue is not well-defined in this case, wouldn't it be better to return NA or NaN or something?) Also,

I'd like to ask for help with a problem in CentOS 5.2 when printing from the command line with the prettyprint option selected. Program students print out their code with the command: lpr -P<printer_name> -o prettyprint -o job-sheets=none <filename_to_be_printed> The prettyprint option, as you know, puts a banner with file name and date at the top, and uses a small font, and

Hi Guys, I've again been surprised when something like > m <- matrix("", nrow=3,ncol=3) > index_i <- c(2,1,3) > index_j <- c(1,3,2) > vals <- c("a","b","c") > m[ index_i, index_j ] <- vals > m gives block-wise application of the assignment: [,1] [,2] [,3] [1,] "b" "b" "b" [2,]

At one point I believe I heard of an R package that would automatically find the most empty space in a plot, and then that answer could then be used to intelligently place a legend. I would like to try to apply that R package to the contrived example shown below, so thank you for any hints or tips that can be provided. x = seq(0, 1000, by = 1) y1_vals<-rnorm(1000, mean = 0, sd = 50)

I've added a few LLVM GDB pretty printers a while back (& just added llvm::Optional earlier today) & thought people might be interested in how to use them, etc. I use them by adding the following to my .gdbinit: source /path/to/llvm/src/utils/gdb-scripts/prettyprinters.py Also, I can suggest adding: set print pretty on there too, it helps a lot when printing complex nested

I'm new to R and very excited about its possibilities. But I'm struggling with some very simple things, probably because I haven't found the correct documentation. Here's a simple example which illustrates several of my problems. Suppose I want to have a regexp match against a string, and return all the matching substrings in a vector of strings. regexp <-

Dear all, I have been working on an idempotent version of apply, such that applying a function f(x) = x (ie. force) returns the same array (or a permutation of it depending on the order of the margins): a <- array(1:27, c(2,3,4)) all.equal(a, iapply(a, 1, force)) all.equal(a, iapply(a, 1:2, force)) all.equal(a, iapply(a, 1:3, force)) all.equal(aperm(a, c(2,1,3)), iapply(a, 2, force))

Excellent. I think it would make sense to add small section somewhere in documentation (e.g. LLVM Programmer’s Manual <http://llvm.org/docs/ProgrammersManual.html>) about it, so it won't be lost somewhere in the mailing list.

I have two vectors, a and b. b is a text file. I want to find in b those elements of a which occur at the beginning of the line in b. I have the following code, but it only returns a value for the first value in a, but I want both. Any ideas please. a = c(2,3) b = NULL b[1] = "aaa 2 aaa" b[2] = "2 aaa" b[3] = "3 aaa" b[4] = "aaa 3 aaa"

Good point - any ideas on where in the programmer's manual would suit best? Looking around I sort of feel like it belongs in the "Picking the right data structure" section - but I fear someone merely examining existing data structures might not think to look there for help in their task (if they have no need to 'pick' a data structure for a new use, etc). On Mon, Dec 19,

I guess adding section "Debugging" at the bottom of programmers manual would sounds like a good plan to me.

I recently traced a bug of mine to the fact that cumsum(s)[length(s)] is not always exactly equal to sum(s). For example, x<-1/(12:14) sum(x) - cumsum(x)[3] => 2.8e-17 Floating-point addition is of course not exact, and in particular is not associative, so there are various possible reasons for this. Perhaps sum uses clever summing tricks to get more accurate results? In some

Added something in r290186. Say, Reid - do you know anything about the MSVC formatters that are also provided in LLVM? Perhaps you could add a brief bit of documentation about them, if they need an explicit wiring up (if they just come for free/automatically - might not be worth documenting, people will find it when they need it) or point this thread to someone who knows about them to provide

What is the recommended class for time of day (independent of calendar date)? And what is the recommended way to get the time of day from a POSIXct object? (Not a string representation, but a computable representation.) I have looked in the man page for DateTimeClasses, in the Time Series Analysis Task View and in Spector's Data Manipulation book but haven't found these. Clearly I can
