Your videos are great and help me a lot!! I hope you can help me out: I want to create 3 factors in a new variable . E.g < 3 --> small, between 3 and 5 --> medium and >5 --> large - how can I use the mutate function in this situation?

Hi there, can you help me out ? I have a graph with 3 categorial values out of 8 marked as "Less than $50, 000", "Less than $75, 000" and "More than $75, 000". I want to make those marked as "High Income" and the other 5 ones as "Low income". How would I do that ?

Hi I used mutate, However it substitutes the values of the variable with large/small. It does not create a NEW variable

Hi!


Was hoping to get some help here, have a dataframe I want to add a new column to, video is doing great showing that so far, but I want the new column to be a random categorical variable. Example with your dataset, I need to create a new column called "type" and I want to randomly assign values either "red" or "green" I was thinking something like mutate(iris, type = ....) I"m not sure what "rand" function could do this. Any help would be appreciated.

Love the videos.


Cheers

Hi there, I hope you could help me out :)
I have a data set and my task is to add 2 dummy variables. They both should indicate 1 if one of the variables, both are strings, contain a certain letter or word.
How would I do that? I read something about the "substring" function but I just can´t figure it out...
