I need help integrating ggplot2 into Excel
Dear all I use ggplot2 extensively for my plotting routines and rexcel to have the best of two worlds.

I have tried the following in Macro mode: Call RInterface.RRun("library(ggplot2)") ... Call

Plotting barplot and scatterplot on same device - x-axis problem
Hi R-users I'm a relative newbie and uses R mostly for graphical purpose. I have a layout problem when plotting a scatterplot and a barplot using par(new=TRUE). The baseline of the x-axis is not positioned equal for the two plotting functions (see picture) and I have been unable to find out how this is changed. http://www.nabble.com/file/p18025066/pic.jpeg I have added the script if this

Buffer in Windows holding samba info
My client is using Samba to read information on their web server from SCO Open Server 5. They are having this problem: Windows holds old information, rather than getting new information from Samba once a file is updated. Is there any way to force samba to go and look for new data everytime Windows makes a request for data? Thanks! -- K-Tag: I've upped my standards. Now up yours! ------

Hello Ulrik, Can you please explain this code means how and what this code is doing because I'm not able to understand it, if you can explain it i can use it in future by doing some Lil bit manipulation.

Hi Hemant, the solution is really quite similar, and the logic is identical: library(readr) library(dplyr) library(stringr) library(tidyr) data_help <- read_csv("data_help.csv") cat_help <- read_csv("cat_help.csv") # Helper function to split the Items and create a data_frame split_items <- function(items){ x <- items$Items_purchased_on_Receipts %>%

Asterisk/InterTel Axxess via MGCP? Anyone?
Hello everyone - first time poster, long time lurker. (sounds like a radio morning program, I know). I'm attempting to get my InterTel Axxess (w/v9.0 software) to play nice with my Asterisk implementation. Asterisk 1.2.6 is running on a Fedora Core 4 x86 box. I've tried getting the Axxess to talk SIP to Asterisk, but InterTel's SIP implementation is, well-let's say, incomplete.

NSD 4.12.0rc1 pre-release
Hi Jannik, What's the rationale behind the "--enable-prometheus-metrics" compile-time option? If this code were compiled by default, would it do any harm? The reason I'm asking this is that features that can be enabled/disabled at compile-time make package distribution complicated. It can result in a scenario where NSD packages on different operating systems or distributions

Hi It seems to me like homework, there is no homework policy on this help list. What do you want to do with your table 3? It seems to me futile. Anyway, some combination of melt, merge, cast and regular expressions could be employed in such task, but it could be rather tricky. But be aware that Suger does not match sugar (I wonder that sugar is dairy product) and you mix uppercase and

nlme R vs S plus
Hi all, I'm a PhD student at sydney uni and am trying to run a non linear mixed model program to obtain estimates of parameters describing dairy cow lactation curves. At present, I have been able to get the data to converge using the S plus (S plus 2000) nlme function. However, when I put the same data into R (R 1.9.0), add in the nlme package and run the code, it does not converge by the

Asterisk + Linksys PAP2-NA / Call Clearing
I have a handful of Linksys PAP2-NA's all talking nicely to Asterisk using standard telephones. I've been running them for the better part of this year. No complaints whatsoever. We chose the PAP2-NA's mainly due to cost and especially the ease of provisioning. In an effort to inexpensively bridge our office PBX (InterTel Axxess) to our VoIP network, we've opted to connect
