Video showing how to filter rows which contain a given string in R using dplyr. We show how to filter the rows of a dataframe in R that contains a string that is given by the user. We also show how to filter rows based on a regular expression. The function that we use to do this is the grepl function. If you ask me, this function is absolutely necessary if you want to become a good data scientist.

But how do you filter when you want a specific string ONLY. Like, what if I only want "apple" but not "apple 1", "apple 2", "apple 3", etc. If I did filter(grepl('apple', df)) I would get all the apples. But I only want the original.

I'm trying to filter for two specific variables Democrat and Republican. How would I go about that this works just fine for isolating one but I don't know how to make it filter for everything except two things.
