I am rather new to R and working on an existing code base heavily using data.table. I understand one of the correct way to add a column or modify an existing one is:
my.table[ , new_column := "New Value"]
However I see in the existing code several calls like:
my.table <- my.table[ , new_column := "New Value"]
I understand that both calls lead to the same result. Is there any good reason I overlooked to prefer the second example?
