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!

#### Jodi Fender

drop_na! ack. Sorry... you can disregard question, except I'll try to see about dropping na from multiple variables at once. You could just delete my comment if you'd like in the moderation review process. :)

No worries! I'll leave it there because it may come up for others. As you may have realized, tidyverse functions tend to use _ between words while base R uses .

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!

I'm not quite sure what you mean. Could you paste your code in so I can see?
