R functions in Julia

You've seen how to use Python functions in Julia, and R is much the same. You use the RCall package which was previously imported, and then use the rimport macro to import the package. Previously you imported base, which is the collection of base functions included in R.

In this lesson you need to define two vectors x and y using standard Julia square bracket syntax. Then the next step is to reverse the order of the vector y, and finally you will plot x vs y on a graph.

Instructions

  • Create two vectors in Julia, one with the values one through four, and the other with values five through eight.
  • Reverse the order of the vector y using the R function rev, passing y as an argument.
  • Plot x vs y on using the R plot function.
