R help - Jul 2004 - Using permax with Data Frame Containing Missing Values

I'm new to this site so I hope this isn't too naive a problem. I'm
trying
to use the permax function with a data frame containing gene expression 
measurements taken from 79 microarray experiments with >3000 genes per 
array. The data contains missing values and every time I use permax with 
the data frame I get the error:

NA/NaN/Inf in foreign function call (arg 1)

Could anyone suggest how I might get round this problem?

There is currently no handling of NAs in permax. Your only simple
option is to drop those rows with NA's in them, or to perform some
sort of imputation.

I will mention it to the package's author, 
 Robert
