1. Which version of Filemaker? NB: Framemaker is a different program
(desktop publishing), so do be a little precise!
2. If it is an ancient version, then I suggest exporting a block of
columns at a time, and then using merge() in R to join it all back up
3. I store all my clinical data in Filemaker 8.5 on the Mac. It is
great. There have been no significant data export or import issues.
One problem (with this version - may be fixed in 9.0) is that
Filemaker ODBC drivers are pretty dreadful and so I do not use ODBC to
access the data held in a Filemaker database. However, Filemaker's
client ODBC access works fine, and, in conjunction with some
commercial ODBC drivers for PostgreSQL, export my data into
postgresql, and then from there import data into R. It is fast and
works very well, albeit in a rather convoluted fashion!
