General Data Wrangling and Analysis Resources
Because most material that discusses data wrangling and analysis with the dplyr packges does so in a way that covers all of the verbs discussed in this course, I have chosen not to separate them by lesson. Instead, here are some helpful resources for learning more about all of the tidyverse verbs discussed in this course:

Hi - I had this working with drop.na (x), but wanted to play around with drop.na for multiple variables if that could be useful in the future. I tried it a couple of ways, but didn't get it to work and then something went wrong and R restarted, so then I loaded packages again, but am still having issues with: Error in drop.na(., education) : could not find function "drop.na" Thanks for any tips!

I accidentally put "education" instead of education and the output returned 1 row of 1000. Is this a potential way to use the count function for qualitative variables? Im not sure I understand why there was 1 row for "education" and 1000 counts. Just curious!
