i found the posdefify, nearcor, and nearPD functions, but can't get things to work. when i tried nearPd, it gave me an dpoMatrix, but i don't know if it would have worked because it said:
"31 x 31 Matrix of class "dpoMatrix" "
right between $mat and the actual matrix and i don't know how to cut that out.

i'm not sure i'm even putting the right variables in the right places, relative to the functions' respective requirements.

sorry about double-posting as well. the web interface for school's email uses some lousy jsp that times out in the middle of emails and whatnot.
