Hello everybody, I found that queries (send by "dbExecStatement" ) with more than 4000 characters length produces an error in ROracle (ver 0.3-3). Maybe there is a limitation of 4kB.... Is this a bug? If yes, is this problem solved in the latest version of ROracle (ver 0.5-0)? My system information: platform sparc-sun-solaris2.8 arch sparc os solaris2.8

Hello everybody, Could anybody give me a hint how I can use "layout" and "filled.contour" (or "image" plot with a color legend) together, please? What I want to do is something like the following example (Two or more plots with a legend for each at one page): data(volcano) layout(matrix(1:2, 1, 2, byrow = TRUE)) for (i in 1:2) { filled.contour(i*volcano, color =

Hello everybody, is there a possibility to install and use multiple versions of a R library at the same time? A few words regarding the background of this question: If I change functions of an already developed package, I have to verify complex functions in a lot of R applications. So it would be useful to use different versions of a function/library and switch to the newer function/library

Hello everybody, could anybody give me a hint, who I can use rbind on a list of data.frames, please? I have a list with a large number of data.frames of the same structure, like: LIST <- list(X1=data.frame(a=1,b=2), X2=data.frame(a=3,b=4), X3=data.frame(a=5,b=6), ...., XN=data.frame(a=i,b=k)) I would like to bind all data.frames very fast to a single data.frame, something like that: DF <-

Dear R community, I tried to optimized my R code by using Rprof. In my R code I'm using MySQL database connections intensively. After a bunch of queries R fails with the following error message: Error in .Call("RS_MySQL_newConnection", drvId, con.params, groups, PACKAGE = .MySQLPkgName) : RS-DBI driver: (could not connect mylogin@mydatabase on dbname "myDB"

Hello everybody, if I try to (r)bind a number of large dataframes I run out of memory because R wastes memory and seems to "forget" to release memory. For example I have 10 files. Each file contains a large dataframe "ds" (3500 cols by 800 rows) which needs ~20 MB RAM if it is loaded as the only object. Now I try to bind all data frames to a large one and need more than

Hello everybody, if I'm running a R-script on a command line R-session which uses the function "try" and I'd like to interrupt the execution of my R-script pressing "CTRL-C" than R ignores the first "CTRL-C" key stroke and after I pressed "CTRL-C" second time R by itself is interrupted and I fall back to the (UNIX-) command prompt.

Hi, Has anyone seen this problem before, and does anyone have a solution? When I query a database using DBI and ROracle to retrieve a date in a format other than the system default, I get a core dump.

Hi all, I've been playing with ROracle (0.5-9) for a few days and I can't wrap my mind around this one. Here's a sample of my R (2.4.0) session. my.df<-data.frame(prd_id=c(123,456),vol_factor=c(.123,.456)) > my.df prd_id vol_factor 1 123 0.123 2 456 0.456 > library(ROracle) Loading required package: DBI >

Hi, first thanks to Sunny Ho (and David James for the pointer) for resolving the problem of the empty rows returned from ROracle. However, I have a problem still: > library(ROracle) > ora <- dbDriver("Oracle") > con <- dbConnect(ora, user = USER, password = PWD, dbname = DBNAME) > rs <- dbExecStatement(con, "select * from USER_TABLES") Error in

Dear list. Has anybody had any issues with ROracle, namely consistently leading to a segmentation fault? One of our oracle databases seems to have certain issues at the moment (do not know what exactly though) and if that one is queried ROracle definitely fails with a segmentation fault. Any ideas? Here is the trace and below is also a type of query that crashes it: *** caught segfault ***

Full_Name: Christian Hoffmann Version: 2.4.0 OS: Win 2000 Submission from: (NULL) (193.134.202.252) Database queries using the combination DBI + ROracle are handicapped by quirks in the pipeline between the textual representation of the query and the database engine Oracle. Comments and linefeed at start are interfering: dbGetQuery(conn, query): works: dbGetQuery(conn, "select *
