Identify Numeric Variables

We identify the numeric variables of a dataset by purrr::map()ing the function base::is.numeric() to find base::which() are numeric. Their names are stored into the variable numc.

# Note which variables are numeric.

vars %>%
  setdiff(ignore) %>%
  extract(ds, .) %>%
  sapply(is.numeric) %>%
  which() %>%
  names() %T>%
  print() ->
numc

## Error in as.vector(y): object 'ignore' not found
