Hello Gunter,

I noticed a minor issue in the source code (cn.mops.R) that if X is originated from a GRanges object, we end up with a matrix of integers instead of numeric/double. I guess the matrix in this case is supposed to be numeric just as if we provide X as a matrix or a vector. While it is is a minor issue, I thought I should still report it since this got me in a bit of trouble while modifying the C++ side of cn.MOPS when using the macros REAL/INTEGER.

 

    if(class(input)=="GRanges"){
        ...
        X <- IRanges::as.matrix(IRanges::values(input))
        ...
        
    } else if (is.matrix(input)){
        if (nrow(input)> 1){
            ...
            X <- input
            X <- matrix(as.numeric(X),nrow=nrow(X))
            ...
        } else{...}
    } else if (is.vector(input)) {
        ...
        X <- matrix(as.numeric(X),nrow=nrow(X))
        ...
    }else{
        stop("GRanges object or read count matrix needed as input.")
    }

Hello Mohammad, Your comments are very welcome - as always! Thanks for flagging this issue. I will make the changes to cn.mops accordingly.
