how do I read them in Markdown?

Could you explain what do you mean with this? is the code for downloading the data included in your rmarkdown file? if so then you don`t need to do anything else.

Ideally, could you ask this with a minimal REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.

If you've never heard of a reprex before, you might want to start by reading this FAQ:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

I am getting the following: Error in common_by(by, x, y) : object 'movieId' not found
Calls: ... as.data.frame -> semi_join -> semi_join.tbl_df -> common_by Execution halted
validation <- validation %>%
semi_join(edx, by = movieId) %>%
semi_join(edx, by = userId)
Note: "validation" and "edx" data.frame(s) are now created above this code!!!!

We don't really have enough info to help you out because we can't know what could be going wrong with your code without seen it first, please provide a minimal REPRoducible EXample (reprex)
