tibble handling

[julienvollering]

Functions are not currently designed to take arguments in class tibble. A toy example of this causing failure is shown below.

The simple workaround is to convert tibble to data.frame before passing to MIAmaxent. More convenient would be to have MIAmaxent handle tibbles.

library(MIAmaxent)
toydata_tbl <- tibble::as_tibble(toydata_sp1po)

plotFOP(toydata_tbl, 2)

#> : span too small.  fewer data values than degrees of freedom.
