exprs(my.rma) <- (exprs(my.rma)[present >= 4, ]) Error in .validate_assayDataElementReplace(obj, value) : object and replacement value have different dimensions

Question

[Sue]

I try to run a tutorial on this line exprs(my.rma) <- (exprs(my.rma)[present >= 4, ]) I got an error : Error in .validate_assayDataElementReplace(obj, value) : object and replacement value have different dimensions

I checked both side of "<-" are class "matrix" "array" . I can run this line : table(present >= 4) output: FALSE TRUE 27820 26855

Thank you

It is likely impossible to help you without any context : which dataset is it ? is there a link to the tutorial ? what is the complete code driving to this error ?
