Well, it would seem that your object 'out' doesn't contain a component called 'p.value'.
Is it possible that you intended out$table$p.value? Since you don't tell us what 'out' is, I can only guess. Perhaps you might read the help function for the function that produced 'out'?
This is not an error in the edgeR package. p.adjust() is not an edgeR function, and this looks like a user mistake anyway.

edgeR error
Hi friends, I am trying to analyse Differential expression using edgeR package and my WT and KO samples.
When I issue the following code at the R prompt
It gives the following error. Any ide?Code:out$p.adjust = p.adjust(out$p.value, method="BH")
All helps appreciated.Code:Error in `$<-.data.frame`(`*tmp*`, "p.adjust", value = numeric(0)) : replacement has 0 rows, data has 20434 Calls: $<- -> $<-.data.frame Execution halted

Metagenomics has improved the way researchers study microorganisms across diverse environments. Historically, studying microorganisms relied on culturing them in the lab, a method that limits the investigation of many species since most are unculturable1. Metagenomics overcomes these issues by allowing the study of microorganisms regardless of their ability to be cultured or the environments they inhabit. Over time, the field has evolved, especially with the advent...09-23-2024, 06:35 AM -
During the COVID-19 pandemic, scientists observed that while some individuals experienced severe illness when infected with SARS-CoV-2, others were barely affected. These disparities left researchers and clinicians wondering what causes the wide variations in response to viral infections and what role genetics plays.
Jean-Laurent Casanova, M.D., Ph.D., Professor at Rockefeller University, is a leading expert in this crossover between genetics and infectious...09-09-2024, 10:59 AM
