Dear "R-listers" I've been trying to figure out how to annotate charts in ggplot (ie add text to line charts, highlighted boxes etc). By and large, I can get close to what i want with base graphics, but would ideally like to use ggplot whenever possible (additionally, i would like to add text labels automatically to the chart). The code is below I suspect I need to use geom_rect,

Hi, I work with SEXP C code and with xts and quantmod packages. I try to touch how xts internal works.

Hello, I have just migrated an old OS/2 file server to a Linux box with Samba 3.0.23a. Now the OS/2 clients crash from time to time. I found a way to reproduce/force the crash using PMMail and did some experiments. The popuplog.os2 on the clients (Warp4 and eComStation) always names a sys3175 in pmshell.exe / doscall1.dll. Using Ethereal and comparing the network traffic between a) a client

Hello, I have a perl program which produces the input. Instead of print it to a file then let R read the file, I want to let R to read the input directly from the perl output, I am using a PERL IPC::open2 module for this, local (*Read,*Writer); $pid = open2(\*Read, \*Writer, "R --no-save --slave< my.R") #input to R for(){ print Writer data; } close Writer; #R output

hi, i am a new member. i am using R in finding correlation between two variables of unequal length. when i use cor(x,y,na.rm=T,use="complete") where x has observations from 1928 to 2006 & y has observations from 1950 to 2006. I used na.rm=T to use the "complete observations". So missing values should be handled by casewise deletion. But it gives me error Error in

Hello- Does anyone have a recommendation on how to call R from perl? I'm using the IPC::Open2 module, and running R with the --slave and --quiet options. The problem is that I can't predict how many lines of output I should try to read for each command-- if any! The ultimate goal is to use perl to provide a form-driven web interface, but have R do the underlying calculations. Thanks

Hi folks. This set of code used to work, but after upgrading to the latest version of Rmetrics it no longer does. Any ideas?

Hi all, The topic of creating a unified API for open3 for Windows came up at RubyConf 2004 this year. Park, I was wondering if you would mind if we modified win32_popen so that the API matches the open3 library that ships with Ruby. This also means deciding whether or not to leave in the open2, open4, and posix stuff. I guess it doesn''t hurt to leave this in, although Open3.open4

Pass -q to virsh if virt-v2v was run with -q, to reduce its output in quiet mode. Unfortunately this does not currently work in virsh as it should, see RHBZ#1358179, so only after that bug is fixed this change can actually take effect. --- v2v/output_libvirt.ml | 20 ++++++++++++-------- 1 file changed, 12 insertions(+), 8 deletions(-) diff --git a/v2v/output_libvirt.ml b/v2v/output_libvirt.ml

Hi all, I have been working through the examples in one of the vignettes associated with the 'mlogit' package, 'Kenneth Train's exercises using the mlogit package for R.' In spite of using the code unchanged, as well as the data used in the examples, I have been unable to run a Wald test to test two models. Specifically, I have run the following command, where mc and mi2 are

Hello Everyone, We are looking to interconnect with a local ILEC over an OC-n transport layer. They basically gave us two options in terms of mapping the SONET to the DS3: * VT1.5s mapping * DS1s mapping The second option is quite clear. We would MUX the connection, and plug the lines into qaud t1 cads etc... The tech mentioned that with the second option we would also need a DACS to convert
