Nesting is a implicitly summarising operation: you get one row for each group defined by the non-nested columns. This is useful in conjunction with other summaries that work with whole datasets, most notably models.

How do I use two functions in R?

  1. Step 1 – Define a list. values <- list(a = c(1, 2, 3), b = c(4, 5, 6), c = c(7, 8, 9))
  2. Step 2 – Create a function.
  3. Step 3 – Use sapply()
  4. Step 4 – Use lapply()
