R Statistics

[parima]

I've got this rather complex calculation that I'm supposed to do to store a value in Filemaker. I actually have the statistition who developed the formula working with me on this and he tells me that I need to either be able to use the log base 1.21 or be able to interact with an R script to get this calculation done.

I only see the option in Filemaker to use log base 10 and the natural log.

Can anyone help me with this? Is there a function that does the custom log or perhaps does anyone know how to interface Filemaker with R? Is there a plugin out there? I've been looking for hours and I haven't found it. Maybe I don't know what to search on.

1. Try:

Ln ( yourNumber ) / Ln ( 1.21 )

2. Have you tried interfacing with R through AppleScript (either directly or by 'do shell script')?
