Dear Rsync Users, Please can I have a bit of rsync advice? I am trying to rsync a file called. 'Draft text - with Holley comments.doc' from machine a to machine b. Unfortunately this isn't working because I think rsync recognises the - character and thinks it's an option. I have tried escaping this out as well as putting it all in " " but neither seems to work

Hi, This is a very simple question I realise, but I hope maybe someone can just help me out. I am trying to do a very simple thing, just transfer a file from machine A to machine B using rsync with ssh. This is what i'm typing: bash-2.03# rsync -avvv --rsh="ssh -l tdf" tdf@machine.niss.ac.uk:/export/home/tdf/demofile.html demofile.html This is what I get: opening connection

Hi, I am fairly new at Rails, and attempting to deploy an application that''s running fine using InstantRails on my PC. On the deployment server (I use railsplayground.net), I get the following error: Processing ApplicationController#index (for 220.224.229.156 at 2008-06-25 18:49:34) [GET] Session ID: 5921e7d789ee3aaa214f2d59aa40986a Parameters: {"action"=>:index,

Disclaimer/Apology: I am an R newbie I am seeing some behaviour that seems to me to be the result of some cacheing going on at some level, and perhaps this is expected behaviour. I would just like to understand the basic rules. What I have is a file with some data. I read it in and then do a summary on the resulting dataframe. I find the some values are completely outside the expected range,

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(expand.dots = FALSE)[["..."]]

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: >

Hello R experten I have just written a little function to calculate all pairwise combinations of two vector arguments: > pair(c(1,2,3),c(7,8)) [,1] [,2] [1,] 1 7 [2,] 1 8 [3,] 2 7 [4,] 2 8 [5,] 3 7 [6,] 3 8 > I want to generalize this to any number of arguments, for example, <fantasy> > ntuple(c(1,2,3),c(7,8),c(14,15)) [,1] [,2]

Interestingly, as.list(substitute(...())) also works. On Sun, Aug 12, 2018 at 1:16 PM, Duncan Murdoch <murdoch.duncan at gmail.com> wrote: > On 12/08/2018 4:00 PM, Henrik Bengtsson wrote: >> >> Hi.

Since you're already using bang-bang ;) library(rlang) dots1 <- function(...) as.list(substitute(list(...)))[-1L] dots2 <- function(...) as.list(substitute(...())) dots3 <- function(...) match.call(expand.dots = FALSE)[["..."]] dots4 <- function(...) exprs(...) bench::mark( dots1(1+2, "a", rnorm(3), stop("bang!")), dots2(1+2, "a",

Dear R-help, Has anyone implemented sparklines in the strips of a lattice plot? What I have in mind is, say, highlighting that part of a time series that one is examining in more detail in a set of lattice plots. Regads,. Mark Difford. PS: (Andreas Loffler has implemented a simple but functional version for TeX/LaTeX: http://www.tug.org/tex-archive/help/Catalogue/entries/sparklines.html)

Dear all, I'm working on some data from an experiment on the breeding behavior of birds. In short, I have been measuring how the time spent on performing a certain task (variable 'mean_on_active') differs over time (variable 'day', 2 levels) across three experimental categories (variable 'treat'; levels 'C', 'R', 'E'). The model shows a

Hi all, I've got a data frame that has an identical column to a chr vector. I would like to use the chr vector to order the rows of the data frame to be identical to the order in the chr vector (the contents of the chr vector are completely identical to one col of the data frame), but this is proving trickier than it sounds.. Any help would be much obliged, -Ken

I want to have something like Facebook has. In some cases when you post something a success message shows up (on the same page, not a pop- up), stays 2-3 seconds and then fades away. How can I do that with Prototype?

Dear R Programmers! After some time of using R I decided to work through John Chambers book "Programming with Data" to learn what these S4 classes are all about and how they work in R. (I regret not having picked up this rather fine book earlier!) I know from the documentation and the mailing archives that S4 in R is not 100% the book and that there are issues especially with

Hi Everyone, When I have a load of functions which have various arguments passed via the ellipsis argument it keeps on assigning them as symbol making them unusable to the function. My current work around involves using do.call but this is rather cumbersome. Does anyone know why it suddenly changes the types to symbol and if there is a way to get the actual data pointed to by the symbol? (I

Hi, I'm confused about the use of ellipsis in function arguments. I'm trying to write a wrapper for plot to automate the combination of plot() and points() calls for a data.frame. Some arguments seem to get passed through to the inner plot, while others cause an error: Error in eval(expr, envir, enclos) : ..1 used in an incorrect context, no ... to look in As a minimal example: tmp
