This is a rewrite of the function `raster.conversion`

from the Vander Zanden
appendix. They expressed things in terms of the standard deviations, but they need to
be turned into variances, anyway, so that is what we've done here. Following the notation
of the paper on Wilson's warbler, this function computes $tildeT^(mu)$ (returned as
list component `mean.raster`

) and $R^(sigma^2)$ (returned as list component
`var.raster`

)

`iso_raster` |

`si` |
slopes and intercepts from the resampled regressions. This is a data frame
with columns named "slopes" and "intercepts" like that returned by |
