Since there doesn't appear to be an RMySQL rpm for SuSE 8.*, does anyone know if the 7.3 version will work with the SuSE 8.2 rpms of R and DBI? The package installs without complaint, but when I try to run con <- dbConnect(dbDriver("MySQL"),dbname="test") I get the error Error in dbConnect(dbDriver("MySQL")) : couldn't find function

Hi, I have simple R question. I have a vector x that contains real numbers. I would like to create another vector col that is the same length of x such that: if x[i] < 250 then col[i] = "red" else if x[i] < 500 then col[i] = "blue" else if x[i] < 750 then col[i] = "green" else col[i] = "black" for all i I am convinced that there is probably a

Hi, I have been developing a small package. It install under RedHat Linux 9.0 without a problem. However, I have a small problem under Windows XP. I am using R-1.8.0 on both systems and HTML Help Workshop 4.74.8702.0 on Windows XP. I created the package under Linux. When I try to install the package created under Linux in Windows XP using c:\rtest> rcmd install rtest I get the following

Hi Laurent, The issue is a very simple one to correct --- you only need to re-install RMySQL with the R version you're currently using. The issue is that the internal representation of objects in the methods package changed in 1.8.0, and thus packages that use S4 classes and methods and save their images (like RMySQL) and were installed prior to 1.8.0 need to be re-installed to be used with

Hi, I have installed RODBC on FreeBSD 4.9 and I am using the PostgreSQL ODBC Driver that is distributed with unixODBC 2.2.8. I can access ODBC Data Sources from Open Office so I think that everything is properly installed.

Hi, I have a integer vector x that contains a unique set of numbers: x <- c(1,2,4,6,8,10,12) Is there a simple test I can use to determine if an integer such as 6 is contained in x ? Thanks in advance for any help, Arend

According David Jame's response to my earlier question, there is a problem with setGeneric.setMethod in R 1.8.0 that affects DBI and RMySQL. Is there a fix for this? David Jame's refers to an 'R-patched version' but I haven't seen anything like this on CRAN. Would going back to an older version of R solve the problem? Thanks, Barnet Wagman "David James wrote:

Hi, I'm trying to use R's DBI interface but it appears to be broken. I am using R 1.8.0 on Linux, and have just installed DBI 0.1-6 through the command 'install.packages("DBI")'. Installation went fine, but now when I try to do a simple dbConnect(), it won't do anything besides complaining about an internal error: > library(DBI) > dbConnect(anything) Error

List, Last week with the help of Uwe and some other folks I was able to get RMySQL 0.5-7 compiled against R 2.4.1 and MySQL 5.0.27. It was working fine--I was able to send select queries to the db, put the results in a data frame, and so forth. Today, dbDriver() threw an error: > dbDriver(MySQL) Error in function (classes, fdef, mtable) : unable to find an inherited method for

Hi all- I am stumped. The code in A. returns errors at lines 14 and 15 and fails to load series1 and series2. However, in B., if temp1 and temp2 are called again (which returns a "Table exists" error; see lines 14-17 in B.) series1 and series2 load correctly. Any ideas? Also-I am open to any suggestions to improve the code as I am a horrific programmer. Thanks A. 1 >
