Hi I'm trying to create a class. However, I've some problems... I am used to program php. There I can create a new object and call a specific function of this object.

I'm having trouble getting RMySQL to load. I was able to build it and install it (RMySQL_0.5-11.tar.gz). I was also able to build and install mysql-5.0.37. I've read many postings about this but have not found a mention of my particular problem (some closely related). I get the "unable to load shared library, no such file" error, but all the files do exist, RMySQL.so and

I don't use MySQL but I have seen messages like this before. They often have replies which indicate that you need to follow the instructions more closely. I suggest you search the list for these previous posts as I'm sure there is help there, somewhere!

Hi all, This is a potentially very stupid question about MySQL <-> R interaction, but I have not been able to solve it. I'm just trying to connect R to my MySQL databse, and gets this: > library(RMySQL) Loading required package: methods > m <- dbDriver("MySQL") > con <- dbConnect(m,group="testdb") Process R segmentation fault at Wed Oct 16 07:04:30

Hi I just started with RMySQL. I have a database with roughly 12 millions rows/records and 8 columns/fields. From all 12 millions of records I want to import 3 fields only. The fields are specified as:id int(11), group char(15), measurement float(4,2). Why does this take > 1G RAM? I run R on suse linux, with 1G RAM and with the code below it even fills the whole 1G of swap. I just

What am I doing wrong, or is the \r that I'm getting in the example below a bug? > a <- (1:10) > b <- (LETTERS[1:10]) > df <- as.data.frame(cbind(a, b)) > > df a b 1 1 A 2 2 B 3 3 C 4 4 D 5 5 E 6 6 F 7 7 G 8 8 H 9 9 I 10 10 J > library(RSQLite) > drv <- dbDriver("SQLite") > con <- dbConnect(drv, dbname = "Test")

Hi! This requires a code change, which is currently in progress. It does require you to patch Dovecot yourself if you want to use it, once it's ready.

Hello, Writing to get some insight as to how I might rid myself of a the pesky error message on the subject. Every binary throws out that error, every LMTP delivery... basically every time any dovecot binary is executed. I am unsure if this is configuration related or not, but intuition says it is an issue with a kernel feature or compiler issue. I saw the error message in the source code

Hi all! I do hope question from newcomers are wellcome here! Thanks in advance.

Hello, I would like to compress a long string (character vector), store the compressed string in the text field of a SQLite database (using RSQLite), and then load the text back into memory and decompress it back into the the original string. My character vector can be compressed considerably using standard gzip/bzip2 compression. In theory it should be much faster for me to compress/decompress

Dear list, I'm working with a MySQL-Table and would like to extract selected ids that are stored in a vector: Ids <- c(1,2,3) How do I insert this variable in a for loop like this: For (a in values) { Temp <- dbGetQuery(con, "select * from db Where id = <ID>";) } My problem is to split the select-statement and insert the current id. How can I handle this problem?
