How to convert log2 scale RNA-Seq expression data to linear scale data

Hi,

We have run a pilot RNA-Seq study and I used edgeR package to obtain differential expression results. The results output a gene column along with the logCPM, logFC and p-value column. I have a question regarding conversion of log2 scale data to linear data for certain analysis. How can this be accomplished. Is there any R package to do this?

For instance, can I use the base function in R like below:

Linear FC value = 2^(logFC)

Linear CPM value = 2^(logCPM)

Thank you,
