For a CSV file I would use 'read.csv()'. I've compiled some notes on reading
in
large data frames into R at

Hi R-Experts,
I'm having a problem with reading a large data file which is
in .csv format and size is 120 MB (app.). I was trying to use RODBC
package but I found RODBCconnectExcel function only. And can I convert
this file to .dbf format? How can I read this file? And also let me

consider using read.csv which is a special case of read.table
?read.csv
as for the RODBC functions, you probably found odbcConnectExcel, but the
help file there mentions a .dbf connections
?odbcConnectDbase
from there using sqlQuery it should be possible to write a .dbf file.
