```
# Update the function definition to fix the na.rm argument
calc_harmonic_mean <- function(x, na.rm = FALSE) {
assert_is_numeric(x)
if(any(is_non_positive(x), na.rm = TRUE)) {
stop("x contains non-positive values, so the harmonic mean makes no sense.")
}
# Use the first value of na.rm, and coerce to logical
na.rm <- coerce_to(use_first(na.rm), target_class = "logical")
x %>%
get_reciprocal() %>%
mean(na.rm = na.rm) %>%
get_reciprocal()
}
# See what happens when you pass it malformed na.rm
calc_harmonic_mean(std_and_poor500$pe_ratio, na.rm = 1:5)
```

When na.rm=1:5, I know we just use its first element 1. Then my problem is what the true or false now? I think 1 means true and 0 means false. But what about 2 (a number neither 0 nor 1)?
