I'm working with a bike share dataset that I've named "all_rides_v02".

Relevant columns are day_of_the_week(self explanatory) and member_casual(rides are logged as either casual or member)

$ ride_id         <chr> "99103BB87CC6C1BB", "EAFCCCFB0A3FC5A1", "9EF4F46C57AD23…
$ rideable_type   <chr> "electric_bike", "electric_bike", "electric_bike", "ele…

$ month           <chr> "08", "08", "08", "08", "08", "08", "08", "08", "08", "…

$ day_of_the_week <chr> "Tuesday", "Tuesday", "Saturday", "Saturday", "Thursday…

I'm trying to create a line graph with multiple(two)lines where one line represents "member rides" and the other line is "casual rides". The x-axis would be day_of_the_week and the y-axis would be the number of rides(which is not explicitly logged in the dataset).

Any advice?

ggplot(data=all_rides_v02)
geom_line(aes(x=day_of_the_week, y=value, color=as.factor(member_casual)))
geom_line()
geom_point()

I could probably post a dozen ways I've done it incorrectly. The main issue I keep running into is that I don't know how to work around not having the "y value". I just want it to be the number of rides.

You'd need to aggregate your data first. If you're using the full tidyverse, you can go

all_rides_v02 %>%
group_by(day_of_the_week, member_casual) %>%
summarise(count = n()) %>%
ggplot()  
geom_line(aes(x = day_of_the_week, y = count, colour = member_casual))
