The errors will be removed/striped when using melt() and dcast(). #46

The errors will be removed after melt() or dcast(), no matter it is reshape2::melt() or melt.data.table().

By the way, It seems the errors package works well in data.table, not for the melt() and dcast() functions though. So make it work for the function melt() would be great!

No, it doesn't work with data.table. To achieve maximum performance, data.table has its own code to wrangle data, and thus it doesn't call the methods that this package provides for errors objects. Therefore, it's not in our hand to make it work. I suggest to use base R methods to work with errors, units or quantities objects. There is some support for dplyr too thanks to vctrs, but it's not 100%.

Ok then I'll use dplyr with errors. Thanks
