# What is a standard approach to binarize microarray gene expression data?

I am using gene expression data from a microarray dataset for the purpose of learning the network structure of genes in the dataset.

Now to do this I need to binarize my data, i.e convert the data for each gene to 0s and 1s. I am new to bioinformatics and am not sure what approach is considered standard for microarray data.

I appreciate your inputs regarding this and I am implementing this in R. So if you know any package that does this please let me know.
