similar to: Request to open up getConnection to embedded interface

I was wondering if there was a function like "does connection exists" ? I am currently using loops to build up a database, and I have either > B = getConnection(localization) Error in getConnection(localization) : there is no connection -2147483648 In addition: Warning message: In getConnection(localization) : NAs introduced by coercion or > B = scan(localization) Error in

Hi, I use the functions socketConnections() and getConnection() which are working fine. Thanks to the authors. After opening nicely some socketConnection, getConnection(3) returns something like : description class mode text opened can read can write "->127.0.0.1:7496" "socket" "wb" "binary" "opened" "yes"

Hello, I'm trying to use the limited connections api defined in Rinternals.h. I have code that looks like this (inspired from do_serializeToConn) : SEXP serialize_to_connection( SEXP xp, SEXP connection ){ Rconnection con ; struct R_outpstream_st out; R_pstream_format_t type = R_pstream_binary_format ; SEXP (*hook)(SEXP, SEXP) = NULL ; con = getConnection(Rf_asInteger(connection));

Hello R developers, I am working on the "seqinr" package and I encounter a tricky problem using a C function. We defined a C fonction called "getzlibsock" which is dedicated to compressed socket connections. This function is using the R internal C function called "getConnection(int)" in order to get information about the socket previously opened with the

When I originally implemented connections in R 1.2.0, I followed the model in the 'Green Book' closely. There were a number of features that forced a particular implementation, and one was getConnection() that allows one to recreate a connection object from a number. I am wondering if anyone makes use of this, and if so for what? It would seem closer to the R philosophy to have

Thought I'd try and start a discussion. Feel free to jump in. I guess R needs to strike the right balance between opening up the internals to package writers and not allowing them to do bad things. My first attempt at cracking this nut is to just memcpy() the Rconnection and not allow access to the private stuff: /* Alternative to allowing C code access to connection API. */ Rconnection

As far as I can tell, 'isOpen' cannot return FALSE in the case when 'rw = ""'. If the connection has already been closed by 'close' or some other function, then isOpen will produce an error. The problem is that when isOpen calls 'getConnection', the connection cannot be found and 'getConnection' produces an error. The check to see if it is

I have been experiencing issues with an R script hanging when connecting to an Oracle database. To help debug, I found a function here in the nabble forum and made a small test script: #!/usr/bin/Rscript --no-restore --no-save --no-init-file library("RJDBC") drv<-JDBC("oracle.jdbc.OracleDriver","/home/oracle/lib/ojdbc6.jar", "'") dbCheck =

I am trying to use R interfaced with MySQL. Present goal is that R should calculate the 85% quantile of AvgSpeed for each LinieID. Looking through documentation of the RMySQL Package, I guessed that dbApply would do the trick due to this example ## compute quanitiles for each network agent con <- dbConnect(MySQL(), group="vitalAnalysis") res <- dbSendQuery(con,

Hello Community, I am installing a domU image via virt-install. However, it seems that a driver needs to be installed for the connection as I saw an error while running the command. Can anyone give any hints about this error? Here is the running script: # virt-install --connect=xen:/// -p -d Thu, 15 Mar 2012 10:17:55 DEBUG Launched with command line: /usr/bin/virt-install --connect=xen:///

Hey everyone, I just wanted to drop onto the list and say hi. My name is Chad Humphries and I am a partner at a ruby and rails shop in Columbus, OH called EdgeCase. Up until two months ago we were doing all of our dev work in test:unit. I had read about RSpec before and after hearing Jim Weirich speak at the Columbus Ruby Brigade about similar ideas I decided to give it a go for a

Yeah, that's often a possible workaround, but since this connection was opened by readLines() internally, I don't necessarily know which one it is. E.g. I might open multiple
