Error in .validate_assayDataElementReplace(obj, value) ; Microarray

Hi everyone,

I am a student who is learning how to do microarray analysis. I ran into the following error and was hoping someone has guidance on how to troubleshoot the issue.

> exprs(my.rma) <- exprs(my.rma)[present >= 4,]

Error in .validate_assayDataElementReplace(obj, value) : 
 object and replacement value have different dimensions

Thank you.
