View source: R/hepi.R

This function evaluates R expressions within the environment of an object of class "hedonic.function".

1	analyse.in.hf(expr, hf)

`expr`	the expression to be evaluated
`hf`	an object of class `"hedonic.function"`

Hedonic functions are often predictions from a regression model. This function allows to easily access the elements in the environment of the hedonic function for further analysis.
