Hi All! I want to create N volcano plots for N subdirectories of .CEL files. Instead of doing each plot seperately, I want to plot them in one mainframe with parameters like par(mfrow=c(N/2,2)). So want to generate a list of expressions of plotting for each subdirectories during iteration over them, and evaluate these expressions collectively with the par(mfrow=c(N/2,2)) parameter. But it turn out to be that arguments in each expressions are unevaluated. Is there any way to solve this problem? Like use different environments? Thank you! Bests!

You might need to post some code, as I am a bit confused as to what you are trying to do and what problem you are having. Sean [[alternative HTML version deleted]]
