...db 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 this code: testdb <- file.path("c:/Salmon_data.mdb") channel <- odbcConnectAccess(testdb) Data <- sqlFetch(channel,"Table1") When I replace it with an Access 2007 file: testdb <- file.path("c:/Salmon_data.accdb") channel <- odbcConnectAccess(testdb) Data <- sqlFetch(channel,"Table1") it does not work. Thanks for any help! Ryan Utz

Hi, Using the fast=F option, sqlSave saves without matching column names. It looks like a bug to me.......... Here's a simple (artificial) example. ----------------------------------------- Create a dataframe and save it to a database table "test" as follows: df <- data.frame(T=1, S=10) sqlSave(channel, df, "test", rownames=F) The table now looks like T S 1 10 If
