I have been successfully using RODBC for a long time (years) to connect to MS SQL Server from R. This week I wanted to try using odbc but I am seeing some problems which may be related to how I set up my driver and/or connection. The dbWriteTable manual page gives as an example command: dbWriteTable( pDB$con, "mtcars", mtcars[1:5,]) When I try this I get the following error Error:

I am using R 2.8 and the latest versions of RMySQL on a Windows XP 64 bit machine. I was wondering if someone could help me figure out how to use dbWriteTable without inserting \r into my table. Consider the following code snippet, which is run after I connect to my database. myDFOut = dbReadTable(conn, "myDF") print(myDFOut) myDFIn = data.frame(x=paste("x", 1:5, sep =

We recently started noticing freezes that appear only on 32bit systems (both linux and windows) with a relatively recent versions of R 3.2.0, including the RC. It looks like the problem can be traced back to the use of R_ObjectTables (see R_ext/Callbacks.h) The problem is a bit difficult to reproduce because it does not appear on x64 and because the official R interface to this functionality, the

Dear Rusers, I am trying to feed my database with data from a file. But since my file (2010101000.txt) there`s no headers I am facing problem because the result data.frame is not separated my columns.

I am feeling rather dumb right now. I created what I thought was a data.frame as follows: aaa <- lapply(split(moreinfo,list(moreinfo$m_id),drop = TRUE), fun_m_id) m_id_default_res <- do.call(rbind, aaa) print("==========================================") m_id_default_res print("==========================================") ndf <- m_id_default_res[, c('mid',

Hi, I have a question reading using RMySQL trying to load one R vector into a table column. To be more specifically, the table is there populated. Now I add a new column and want to populate this.

Hello, When I do: dbWriteTable(con, "r.BOD", cbind(row_names = rownames(BOD), BOD)) ...can I specify the data types such as varchar(12), float, double precision, etc. for each of the fields/columns?

I am at loss of what is going on here ... I am trying to write to a SQLite database: con <- dbConnect(dbDriver("SQLite"), dbname="pres-docs.rqda") I have a data frame that is 889 rows by 7 columns.

If I save a dataframe with a character-typed last column to a relational database with dbWriteTable, the values in the last column of the resulting table in the database will have a '\r' (carriage return) appended. If I read back the dataframe with dbReadTable the last column in the resulting dataframe has also '\r' appended (see protocol below). Setting or unsetting sql-mode

I tried aov(c(y1,y2,y3)~x) which seemed reasonable to me but doesn't work. How
