I'm thoroughly stumped. I've been playing with RODBC and wanted to see
if I could retrieve data from text files using this package as well (for the
most part, this is an intellectual exercise, but occasionally I do get data
files large enough in CSV format RODBC could be helpful) .
I set up a DNS called "Text Files" and then ran the following code in
R
> library(RODBC)
> mtg <- odbcConnect("Text Files")
> sqlTables(mtg)
TABLE_CAT TABLE_SCHEM TABLE_NAME TABLE_TYPE
REMARKS
1 C:\\USERS\\NUTTERB <NA> Core2012.txt
TABLE <NA>
2 C:\\USERS\\NUTTERB <NA> MTGCards.csv
TABLE <NA>> sqlFetch(mtg, "MTGCards.csv")
Error in odbcTableExists(channel, sqtable) :
'MTGCards.csv': table not found on channel>
MTGCards.csv is an export from an MS Access database, and I'm able to get it
out of Access, and I'm also able to connect to our Oracle databases. So
I'm not sure what it is I'm not getting about reading the text files.
If anyone has done this successfully and has any pointers, I'd appreciate
it. So far I've not been able to solve it with documentation from RODBC,
RStudio (I get the same error messages when I use the RGui), or Microsoft ODBC
drivers.
Windows 7, 32 bit
