[R] command line boa problems...

[Evan Cooch]

Greetings -

For a number of reasons, I'm moving from CODA to BOA - and I have one or 
two really basic, boa-newbie questions. While I have the 'menu-driven' 
version of boa working fine (most recent version, running under R 2.3.1 
on a Windows machine), for the life of me I can't seem to get some basic 
boa.xxxx command-line functions to work at all. Even things like 
boa.version() or boa.license() return errors. But, boa.init() and other 
functions seem to work fine.

At this stage, I'd be happy getting the first - fairly key - function to 
work - boa.importASCII. My MCMC sample data are in a flat ASCII file 
(white-space delimited), called practice.txt. There are two columns in 
the file (iteration number, parameter value), both labeled in the first 
row of the file (as per instructions in the boa documentation). I know 
the file is formatted OK, because I can import and play with it 
successfully using the boa.menu() approach. But, for some reason, 
boa.importASCII won't touch it.

Suppose the file is on my desktop (remember, windows machine)

I've tried all the variuous front-slash, back-slash, double-slash etc. 
combinations I can think of...

boa.importASCII(practice,"c:\documents and settings\eg7\desktop")

boa.importASCII(practice,"c:\\documents and settings\\eg7\\desktop")

boa.importASCII(practice,"c:/documents and settings/eg7/desktop")

boa.importASCII(practice,path="c:/documents and settings/eg7/desktop")

boa.importASCII(practice,path="c:\\documents and settings\\eg7\\desktop")

and so on...and so on...in each case, boa.importASCII reports that

Error in paste(prefix, boa.par("ASCIIext"), sep = "") :
       object "practice" not found

or something to that effect - basically, practice.txt isn't being found.

Help! 

Thanks!
