Sorry to take so long getting back to you.
Can you supply some sample data and perhaps a bit of code.,
We need a reproducible example (reprex)

A handy way to supply sample data is to use the dput() function. See ?dput. If you have a very large data set then something like head(dput(myfile), 100) will likely supply enough data for us to work with.
