Fuzzy Matching: avoiding "Error: $ operator is invalid for atomic vectors"

QUESTION

Fuzzy Matching: avoiding "Error: $ operator is invalid for atomic vectors"

Asked 2017-Nov-28 at 18:32

I understand that "Error: $ operator is invalid for atomic vectors" is caused by passing $ to the wrong kind of object: an atomic one instead of a recursive one.

However, I get it when I run a code chunk that works for other people. I'm trying to find what I'm doing wrong or an alternative solution.

I have two data frames:

...

You are running into issues because DF1 and DF2 are both single column data.frames. When you subset a single column data.frame it drops the data.frame class and returns a vector. Thus using $ won't work. To get around this you can do either:

Select the specific column you want in the subsetting. For your code for DF2 this would be DF2[c2.1, "coolThings"].

Use drop = FALSE to make sure your subsetting doesn't return a vector. For DF2 this would look like DF2[c2.1, , drop = FALSE]$coolThings.

I personally prefer method 1, but both should work.
