I am trying to convert pvalues to qvalues. Here's the command I give: qvals.sample1= qvalue(pvals.sample1) q.vals.sample1= qvals.sample1$qvalues and it returns [1] "ERROR: The estimated pi0 <= 0. Check that you have valid p-values or use another lambda method." Error in qvals.LEC1RT$qvalues : $ operator is invalid for atomic vectors -- View this message in context: http://r.789695.n4.nabble.com/qvalue-error-tp4686673.html Sent from the R help mailing list archive at Nabble.com.
