Import of Access data via RODBC changes column name ("NO" to "Expr1014") and the content of the column
Dear all, I have some problems with importing data from an Access data base via RODBC to R. The data base contains several tables, which all are imported consecutively. One table has a column with column name "NO". If I run the code attached on the bottom of the mail I get no complain, but the column name (name of the respective vector of the data.frame) is "Expr1014" instead

BUG in RODBC() on Ubuntu 64amd : rows_at_time=1024
R 2.8.1 Ubuntu 64amd RODBC 1.2-5 --------------------------------- This was a hard-to-track bug for me, because sqlQuery() did not fail - instead, it looked like it returned some good data and some NA where there should have been numbers and 0 where there should have been NAs. I did: (a) sqlQuery( o, qry, as.is=TRUE, errors=TRUE, rows_at_time=1024 ); (b) sqlQuery( o, qry, as.is=TRUE,

RODBC performance seems slow
I've noticed that RODBC seems to be an order of magnitude slower in retrieving rows from a table than ODBC (or JDBC) access in other tools. I'm wondering why that is, and whether there are things I can do to improve performance beyond what I've tried. I've checked the documentation, and have tried the rows_at_time= and buffsize= options, which helped a little, but it is still

Importing Access 2007 data with ROBC
Hi all, I'm trying to import Microsoft Access data into R. It looks like I'm supposed to use the ROBC package, and this works fine with old Access files (those with an .mdb extension). However, lovely Microsoft must constantly update their software. Modern Access files have an .ACCDB extension. I cannot seem to coerce R to import data from such a file. Any advice? I've been using

1. Can I avoid having RODBC use so much memory (35 times the data size or more) making a data.frame & then .rda file via. sqlQuery/save? 2.
