Help with error message

[system]

Hey everyone,

Below is my code:

In addition: Warning messages:

1: In xy.coords(x, y, xlabel, ylabel, log) : NAs introduced by coercion

2: In min(x) : no non-missing arguments to min; returning Inf

3: In max(x) : no non-missing arguments to max; returning -Inf

What can I do to fix this error message? Not sure what I’m doing wrong

Thanks.

plot(log(dat$nSpp)~dat$Habitat

plot() requires as its argument coordinates of points, each of which must be numeric, while habitat is character. Think of how you would do this with graph paper to see the problem with that—how many centimeters on the page between forest and bog on the y-axis?

dat <- data.frame(
  site =
    c("TPB", "TPB", "HBC", "HBC", "CKB", "CKB"),
  lat =
    c(42.00333, 42.00333, 42.02889, 42.02889, 42.04944, 42.04944),
  lng =
    c(73, 73, 70, 70, 71, 71),
  elev =
    c(389, 389, 8, 8, 152, 152),
  nspp =
    c(6, 5, 16, 6, 18, 14),
  habitat =
    c("forest", "bog", "forest", "bog", "forest", "bog"))

(log_nspp <- log(dat$nspp))
#> [1] 1.791759 1.609438 2.772589 1.791759 2.890372 2.639057

Looking at the last line of the reprex just above, what about the associated habitats to you want to display with the nspp numbers?
