R is not for Relational, but could be... I was musing on data.frames when I decided what I needed was a SQL like 'select' statement. Before I get involved in writing something like that, has anyone else written anything that allows a relational like algebra on data.frames?

It appears that julian() is in R-base, but julian.default() is in the chron package. > search() [1] ".GlobalEnv" "package:ctest" "Autoloads" "package:base" > julian(1:3,4:6,1991:1993) Error in julian(1:3, 4:6, 1991:1993) : no applicable method for "julian" > find('julian') [1] "package:base" >

I used to run the julian function from chron but this new version of R has also a julian function in the base package that doesn't do exactly what I need. Is there a way of telling R to run the function from chron and not from base? Thanks, Fernando __________________________ Fernando Colchero Doctoral Fellow Duke University Department of Ecology

Hi All I just completed a custom application for Asterisk (i m not a C guru so i just copy codes from other application and alter according to my needs) attached files is the source file this application is working fine but still i need you people to give suggestion to improve it Primary task of this application is to get a parameter from extensions.conf, query sql server and play a files

Thanks to David's help I subset my large data set and produced a smaller one for a single stream and 7 factors of interest. The structure of this data frame is: str(burns.tds.anal) 'data.frame': 718 obs. of 4 variables: $ site : Factor w/ 143 levels "BC-0.5","BC-1",..: 1 1 4 6 4 4 4 5 5 5 $ sampdate: Date, format: "1996-06-02"

This is my first excursion into using reshape2 and I want to ensure that the melt() function call is syntactically correct. The unmodifed data frame is organized this way: head(tds.anal) site sampdate param quant 1 UDS-O 2006-12-06 TDS 10800 4 STC-FS 1996-06-14 Cond 280 7 UDS-O 2007-10-04 Mg 1620 9 UDS-O 2007-10-04 SO4 7580 19 JCM-10B 2007-06-21 Ca 79 20

A data frame has one factor, one date, and one numeric column. When I plot these using the default pch of the open circle (first attachment), xyplot(TDS ~ sampdate | she.s, data = sheep.cast, main = 'TDS in Sheep Creek', ylab = 'Concentration (mg/L)', xlab = 'Time') I see the higher concentration points toward the right on several panels. But, when I change to using a

Both of our production asterisk servers are dumping core when making writes to our cdr tables. Here is a backtrace of the problems we are having: #0 0x00447b1f in tdserror (tds_ctx=0x1, tds=0xb7938c90, msgno=20004, errnum=9) at util.c:347 347 if (tds_ctx && tds_ctx->err_handler) { (gdb) bt #0 0x00447b1f in tdserror (tds_ctx=0x1, tds=0xb7938c90, msgno=20004, errnum=9) at

I would like some Asterisk community input: It was requested of me to create an Asterisk FreeTDS (cdr_tds.c) module to allow Asterisk to populate MS SQL Server (and Sybase) with CDR records. unixODBC has been thrown around as a bright shiny button but it adds an additional layer of DB abstraction. That additional layer of abstraction can cause problems when it is not necessary for our TDS (MS

I believe that I have a basic understanding of zoo and how to use read.zoo on a text file, What I have not seen in the zoo help files and vignettes is how to convert a data frame to a zoo matrix for irregular time series analyses. An example data frame is structured like this: str(burns.cast) 'data.frame': 256 obs. of 47 variables: $ site : Factor w/ 143 levels

I have measured values for 47 chemicals in a stream. After processing the original data frame through reshape2, the recast data frame has this structure: 'data.frame': 256 obs. of 47 variables: $ site : Factor w/ 143 levels "BC-0.5","BC-1",..: 1 1 1 2 2 2 2 2 2 2 ... $ sampdate : Date, format: "1996-04-19" "1996-05-21" ... $ Acid :

Hi, I did upgrade the server to Windows Server 2008 R2 along with AD. However, when I attempt to add Samba-4 as additional domain controller, it is able to provision the Domain and starts to replicate the data. However, while replicating, it throws up an error as shown below and stops. Samba-4 will remove itself being additional domain controller. I tried this migration using Samba Version

Hello all, I am trying to connect to my remote MS SQL server from Ubuntu. I have followed HowtoConnectToMicrosoftSQLServerFromRailsOnLinux<http://http://wiki.rubyonrails.org/rails/pages/HowtoConnectToMicrosoftSQLServerFromRailsOnLinux>as best that I can. TSQL is working, example below. My configs are found below. When I run isql : > isql -v pubs name password [IM002][unixODBC][Driver

I have installed Asterisk with FreeTDS many times before (this same Asterisk and same TDS version)... but today when I did the make it gave me this error: ake[1]: Entering directory `/home/matth/asterisk126/asterisk-1.2.6/cdr' gcc -pipe -Wall -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -g3 -Iinclude -I../include -D_REENTRANT -D_GNU_SOURCE -O6 -march=i686

A little off topic this morning...I'm thinking about switching out of Comast's clutches to another high-speed service. I've tried TDS DSL, but they were half the speed comast was/is. I''ve looked into Speakeasy, since I heard a few of ya talking about them. Since I had TDS, that kinda tells me I can get DSL. I live in Mount Juliet, on MT juliet road, behind the

All but one of the summaries of multiple linear regressions in this analysis set present the residuals by min, 1Q, median, 3Q, and max. Example: lm(formula = TDS ~ Cond + Ca + Cl + Mg + Na + SO4, data = snow.cast) Residuals: Min 1Q Median 3Q Max -277.351 -32.551 -2.621 40.812 245.272 The one that doesn't has only a small number of rows (23) and presents the

I have Asterisk 1.4.32 and I would like save all VoiceMail to MSSQL 2008 database. I configured ODBC, but I receive this errors.

Please provide a pointer to the source of this problem so I can understand why it occurred.

Working with 5 subset streams from my source data frame, three of them successfully call dcast(), but two fail: jerritt.cast <- dcast(jerritt.melt, site + sampdate ~ param) Aggregation function missing: defaulting to length and winters.cast <- dcast(winters.melt, site + sampdate ~ param) Aggregation function missing: defaulting to length Yet both data frames have the values in their
