Access data.table columns with strings

Question

Apologies for a question that probably makes it obvious that I usually work in Python/pandas, but I\'m stuck with this. How do I select a data.table column usin

Answer 1

You can do assignments without get but using brackets:

dt[, ("col1"):=col2]

instead of:

dt[, get("col1"):=col2]

See for more explanation: Select / assign to data.table variables which names are stored in a character vector
