After running the script fix:

create file path to swirl lesson file

file_path <- file.edit(file.path(find.package("swirl"),"Courses","R_Programming","Logic","lesson.yaml"))

url of my edited lesson file

file_url <- "https://raw.githubusercontent.com/daniel-j-miller/swirl_courses/master/R_Programming/Logic/lesson.yaml"

download and save file

download.file(file_url, file_path)

I still get an error: Error in download.file(file_url, file_path) : invalid 'destfile' argument

Any suggestions?
