may you drop me some idea how can i get rid of following error message:
Error in switch(nmeth, { : NA/NaN/Inf in foreign function call (arg 1)
i dont know what does nmeth and ther rest of error message mean? i have 
a file which contains 460 rows and 174 columns including missing value 
as NA.

I assume that you are using R on some silicon-based electric circuit, but 
that's about all I can guess to understand the error message. In what command 
did it occur? Possibly "read.table"? And try 

  traceback()

after the error message. And if it is during read-in of data, shorten your file 
to 3 lines and try again.
