Dear R-users, In the R internals manual, it is said that one can extract the elements of the dot-dot-dot argument using the special symbols ..1 or ..2. It seems to work just fine but I was wondering if there is a way one can extract or modify the content of the dot-dot-dot argument using a level name instead of its position? For instance, assuming that list(...) returns: $a [1] 1 2 3 4...

Hi. For any number of *known* arguments, we can do: one <- function(a) list(a = substitute(a)) two <- function(a, b) list(a = substitute(a), b = substitute(b)) and so on. But how do I achieve the same when I have: dots <- function(...) list(???) I want to implement this such that I can do: > exprs <- dots(1+2) > str(exprs) List of 1 $ : language 1 + 2 as well as: > exprs <- dots(1+2, "a", rnorm(3)) > str(exprs) List of 3 $ : language 1 + 2 $ : chr "a" $ : language...

Hi, i need to recognize itemization structures in strings which follow the format: "digit-digit-dot" like e.g. 1. 2. 19. 211. Given the string " This happened in the 21. century." (the dot behind 21 is used in German instead of 21st) I want know where the dots are but I do not want the 21.-dot to be returned as well. I am not good at regular expressions. How can I re...

hi folks, Bit of a newbie, but I've spent a fair bit of time looking for an answer on this, with no joy. Can anyone help me? Dataset: A single column of values in a csv file (eg. 52, 53, 54, 85, etc) Goal: In Minitab, you have what they call a dot plot. It's a histogram, where a single dot represents a set of identical values (eg. 57, 57, 57 would be one dot). Multiple dots are stacked on top of each other (as if gravity was affecting them). The advantage is that outliers are very visible (since a single 155 still gets a single dot)....

Hi, A few months ago, I mentioned I was interested in helping to make dot releases for LLVM 3.3. Now that 3.3 has been released, I would like to kick off the process of collecting bug fixes and merging them into the 3.3 branch. I reviewed the previous discussion about dot releases: http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-April/060821.html and I've come up w...

I could not find any documentation of how dot-dot-dot works when used as an argument in a function call (rather than as a formal argument in a definition). I would appreciate some references to the rules governing situations like: f1<-function(x,y,...){ ? print(x) } f2<-function(...){ ? f1(...) } f2(1,2,3) In the call above how are t...

Thanks all, this was very helpful. Peter's finding - dots2() below - is indeed interesting - I'd be curious to learn what goes on there. The different alternatives perform approximately the same; dots1 <- function(...) as.list(substitute(list(...)))[-1L] dots2 <- function(...) as.list(substitute(...())) dots3 <- function(...) match.call(ex...

Recent R function names seem to be using CaseOfTheLetters to mark words rather than dots as was done previously. Is the use of dots in function names deprecated, or is that simply a style choice? Will function names with dots cause problems in future revisions? Mike Prager

Dear all, I am creating functions with the "three dot" strategy. I wold like to have suggestion when writing multiple functions that calls multiple functions with "...". I will give you a couple of example: >a=1:5 >b=6:10 >d=3:7 >example=function(x,y, z, ...){ plot(x,y, ...) points(x,z, ...) } >example(a,b,d)...

All, This is probably a bit more of a mac question, but here goes. (Admission: I posted this to ruby-talk as well....) I am trying to use rdoc -d to generate class diagrams on a mac running Tiger (OS X 10.4) for a rails app. I managed to get dot installed, but now am running into problems with dot looking for libraries that either do not exist or are apparently in the wrong place. I probably made things worse by trying (at various times) both Darwin ports and i-installer. Can anyone point me to instructions on getting this working? BTW, t...

Hello, Thanks in advance for any help! How do I pass an unknown number of objects into the "..." (dot dot dot) parameter? Put another way, is there some standard way to pass multiple objects into "..." to "fool" the function into thinking the objects are passed in separately/explicitly with common separation (like "x,y,z" when x, y and z are objects to be passed into &...

...re not allowed as syntactic names (see make.names). They **are** allowed as non-syntactic names, e.g. inside backtick quotes." `..1` and `...` are allowed for assigning, but these symbols cannot be used in the context of a variable.

...(S). You transmit, m, s, |L|, and |R|. The decoder needs to find unknown positive constants a and b to compute L = a*m + b*s R = a*m - b*s To find a and b, we use two constraints |L|^2 = |a*m + b*s|^2 |R|^2 = |a*m - b*s|^2 That proceeds as follows: |a*m + b*s|^2 = a^2*|m|^2 + b^2*|s|^2 + 2*a*b*dot(m,s) = a^2 + b^2 + 2*a*b*dot(m,s) = |L|^2 |a*m - b*s|^2 = a^2*|m|^2 + b^2*|s|^2 - 2*a*b*dot(m,s) = a^2 + b^2 - 2*a*b*dot(m,s) = |R|^2 We now compute the sum and difference: sum: 2*(a^2 + b^2) = |L|^2 + |R|^2 a^2 + b^2 = (|L|^2 + |R|^2)/2 difference: 4*a*b*dot(m,s) = |L|^2...

Hello, I hope to plot my data in a dot diagram, something like the output of the last example of layout function in graphics package. The only difference is that I need the rectangle in histogram is replaced by dot. Thanks in advance. Best wishes, Jinsong Zhao

Hello I set up Samba 3.0.28,1 on a FreeBSD 6.3 host.
