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 have a function as follows: my.plot <- function( x, y = NULL, ... ) { plot( x, y, cex.axis=0.5, ...) } Set up the variables: x <- 1:10; y <- x; tdf <- data.frame( x, y ); main.str <- "test" I will exercise the function in two ways: > my.plot( y ~ x, tdf, main = "test" ) This works fine > my.plot( y ~ x, tdf, main = main.str ) Error in

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,

Or to put it another way, is there a function f, such that Inflector.f(Inflector.Camelize(x)) = x ? Enquiring minds need to know. Adelle.

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

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, Just wondering if anyone had seen this before. I did a simple install following Paul Goscicki''s tutorial (http://paulgoscicki.com/archives/2005/09/ruby-on-rails-on-ubuntu/) and I get this message when I type "rails test" from the command line.(I''m running Ubuntu 5.04 Hoary) could anyone point me in the right direction? thanks. --max

Is there a command for partial matching of character strings? Specifically, I'd like to be able to calculate the mean of the values in any columns in a data frame or matrix that have identity in part of their column names. For example, columns labeled "mpw06a" and "mpw06b" match on the first five characters; their mean would be taken whereas any columns beginning with

Hi all, I''ve created and submitted a patch to resolve an issue I had while attempting to meet the OpenSocial API specifications, which dictates that the xml output have tags formatted as lower camelcase (as opposed to upper camelcase, which is currently the only option). With this patch, simply passing :camelize => true still begets the current behavior, but you can now enable lower

Hello.
