I want to perform some operation to the assay data of MSnSet within a MSnSetList but I think its now allowed. Could you please let me know how to do such a thing?
A simple example is shown below.
dun <- split(dunkley2006, "replicate")
exprs(dun[])[1,1] <- 1
Error in `[[<-`(`*tmp*`, 1, value = <S4 object of class "MSnSet">) :
[[<- defined for objects of type "S4" only for subclasses of environment
