Question about how to solve the error of lines() in R Markdown
23 March 2022, 11:47 PM
I have an error of lines() in R Markdown. The code in R Script has no error. So I'm writing for help.

I solve it by using this code, but I don't know whether it is the optimal solution.

The lines() function is so-called a low-level function. It cannot work alone. It must be based on an existing graph, created by a high-level function such as plot(). We usually do it like this:
plot(age, bone, pch = 16)
lines(av, bv)
Other low-level functions include axis(), points(), legend() ... Other high-level functions include pairs(), boxplot(), hist() ...
BTW, please post your code rather than the screenshot, so that other people do not have to type your code and test it.
