Tidyverse and new variable #744

Closed famax2 closed 3 years ago

famax2 commented 3 years ago

Hi, I'm working on survey data and I want to create a new variable from an existing variable data. The existing variable 'medication' has names of the medicines the participants used as text. I want to create a new variable 'Iron' that flags 1 if the medication variable has "iron" in it. I also want to create another variable 'folate' that flags 1 if the medication variable has folate in it.

The medication variable has different names of the same drug written either as e.g., iron, or many drugs e.g., iron, paracetamol, ironsupp etc.

Hi @famax2, this doesn't look like an issue with the lesson material to me. A good place to ask questions like this is https://community.rstudio.com/ or https://stackoverflow.com/

For more info on where and how to ask for help, see https://datacarpentry.org/R-ecology-lesson/00-before-we-start.html#Asking_for_help

Anyways, you can probably achieve what you are trying to do with a combination of mutate(), str_detect(), and as_numeric()
