Hi, I'm trying to extract the information from a dataset. I'm doing: dmr<-which(is.element(iDMR, data)) iDMR is an object on the package I'm using that has a list that I want to extract from my dataset. The problem is that iDMR is of type "closure" and to perform the above I need a vector. I've tried as.vector, but it doesn't work. How can I transform iDMR into a vector?
