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?

Using permax with Data Frame Containing Missing Values

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
