Hi Ed,
Can you please provide *at least* the R output from running:
str(data)
where "data" is the variable name you stored the results of readMat()
in. If it is reasonably small and can be sent as plaintext (I do not
know Matlabs file format off hand), you could send us the actual data
so we can try to read it in, but at the least str() will let us see
how R is storing your data and give you some explanation.
Side note, as data() is a function, it might be worthwhile to call
your actual data something else (say, mydata, dat, etc.). For anyone
else interested, readMat() is in package "R.matlab".
Cheers,
Josh
