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 trying to run Solaris 10 under Xen but I have few problems. First of all, there are some weird errors while booting up system.

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,

Hello guys.I just read up about tf-idf schemes and want to implement it in Xapian (with some frequently used normalizations) as it will also give me a good hang of implementing a weighting scheme before I start working on implementing DFR schemes. I read the following as references and I think Ive understood it well and can write the hack :- 1.)

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

Sir, I have hit a the limits of my understanding of text / par / opar etc... I have a few related xts data frames which have multiple columns, and have written a for-loop to make a set of charts - however i do not get any margin text when i run the loop. when i test the code outside of the loop the margin text appears - however when i run the loop the margin text does not appear ... what gives?

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

Dear list, I would like to expand a DF with all the missing levels of a variable. a <- c(2,2,3,4,5,6,7,8,9) a.cut <- cut(a, breaks=c(0,2,6,9,12), right=FALSE ) (x <- data.frame(a, a.cut)) # In 'x' the level "[0,2)" is "missing". AddMissingLevel <- function(xdf) { xfac <- factor( c("[0,2)", "[2,6)", "[6,9)",

Hi All, I am trying to run a loop that will have varying numbers of rows with each output. Previously I have had the same number of rows so I would use (and I appreciate that this will no doubt achieve some gasps as being thoroughly inefficient!): xdfrow<-(0) xdfrow1<-(1:32) xdfrow2<-(33:64) xdfrow3<-(65:96) xdfrow4<-(97:128) xdfrow5<-(129:160) xdfrow6<-(161:192)

hi guys i have multiple data frames which i want to merge. there are four of them..eg pdf SampleID UVDose_J RepairHours Day_0 Day_45 Day_90 1 SDM001 1.0 3 485.612 465.142 490.873 2 SDM001 1.0 3 503.658 457.863 487.783 3 SDM001 1.0 2 533.193 451.044 456.973 4 SDM001 1.0 2 538.334 452.887 474.915 5 SDM001 1.0

I appear to have hit one of the "drop" issues raised in some discussions a couple of years ago by Frank Harrell. They don't seem to have been fixed, and I'm under some pressure to get a quick solution for a forecasting task I'm doing. I have been modelling some retail sales data, and the days just after Thanksgiving (US version!) are important. So I created some dummy

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,

It depends on
