Common problems with data frames in R

It is rather obvious to say, but data frames in R are one of the most interesting features of this programming language. However, sometimes they might not be the easiest to understand and use.

The DataCamp Team referred to the fact that “R’s data frames regularly create somewhat of a furor on public forums like Stack Overflow and Reddit.” Therefore, they selected issues “from the most recent and sticky or upvoted Stack Overflow posts” and they offered a detailed solution for them.

You may read a lot of recommendations about data frames modifications, easy access, application of functions, extraction or merging.
