dict package: dictionary data structure for R
Hi all, The dict package provides a dictionary (hashtable) data structure much like R's built-in environment objects, but with the following differences: - The Dict class can be subclassed. - Four different hashing functions are implemented and the user can specify which to use when creating an instance. I'm sending this here as opposed to R-packages because this package will

python-like dictionary for R
Hi, I was wondering if anyone has played around this this package called "rdict"? It attempts to implement a hash table in R using skip lists. Just came across it while trying to look for simpler text manipulation methods: http://userprimary.net/posts/2010/05/29/rdict-skip-list-hash-table-for-R/ Cheers, Paul [[alternative HTML version deleted]]

RSQLite 0.6-7 -- changes to dbGetQuery semantics
RSQLite 0.6-7 has been uploaded to CRAN and should hit a mirror near you in the next few days. This version changes the behavior of the dbGetQuery method to make it more consistent with dbSendQuery. Specifically: 1. dbGetQuery now closes a complete result set as dbSendQuery does. 2. If there is an incomplete result set open, dbGetQuery still opens a new temporary connection, but now issues

Suggestion: isLoaded() to test if a package is loaded (without loading it)
Hi, for 'affxparser' (Bioconductor), we needed a function to test if a certain package was loaded or not, but we did not want to load it if it wasn't, which is why we couldn't use require(). We came up with the following solution: isPackageLoaded <- function(package, version=NULL, ...) { s <- search(); if (is.null(version)) { s <-

RSQLite bug fix for install with icc
Seth, I encountered problems installing RSQLite, R-2.7.0, on RHEL4 using Intel 10.1 icc, My sysadmin helped me track down the problem and kindly forwarded me the fix, which corrected the problem. What follows is from the sysadmin. Mark I looked at the error, looks like there is a bug in the source code. I've attached a new tarball, hopefully fixed. I added #include <sys/types.h>

isOpen on closed connections
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

S4 coercion responsibility
Should functions or the user be responsible for coercing an S4 object argument containing the proper object (and thus should below be considered a bug in the packages or not)? The example is with RSQLite but the same thing happens with RMySQL, and other DBI packages. > library("RSQLite") Loading required package: DBI > m <- dbDriver("SQLite") > con <-

Side-effects of require() vs library() on x86_64 aka amd64
RDieHarder fails its regression tests on x86_64 (aka "amd64") at CRAN (using Debian), and I see the same on Ubuntu 8.10 in 64 bit. No issues on 32bit. One odd thing is that the program behaves well if run via R --no-save < tests/RDieHarder.R but NOT when started using R --slave < tests/RDieHarder.R as R CMD check does. So I tried different things related to startup

Call C code from R
Hello, All! I have function which is written in C, the function uses other functions also builded bu me. Now I need to use the function to build R function. My questions are: 1. How can I include libraries (for example, iomanip, sstream, tcl.h)? 2. Should I put other function to the separate file and then include the file?
