The melt generic in data.table has been passed a matrix, but data.table::melt currently only has a method for data.tables. Please confirm your input is a data.table, with setDT(Q) or as.data.table(Q). If you intend to use a method from reshape2, try installing that package first, but do note that reshape2 is deprecated and you should be migrating your code away from using it.
