Hi all,

I'm interested to use genegeneinteraction R package. For that data are read and a snp matrix is generated. When I try to run gene gene interaction I get error

 GGI.res <- GGI(Y=Y, snpX=data$snpX, genes.info=data$genes.info,method="PCA")

Error:

Error in GGI(Y = Y, snpX = data$snpX, genes.info = data$genes.info, method = "PCA") : The snpMatrix must be complete. No NAs are allowed.

I am unable to get my way through this (snp matrix) data structure.

Can anyone help in order to use signature function:

temp<-data$snpX [signature(x="temp",drop="missing")]  
 signature(x="temp",drop="missing")  
 []signature(x="temp",drop="missing")

Also, I'm interested to view contents of it, but unable to print or subset them in readable manner.
Thanks.
