I am trying to replace a spreadsheet model of a project justification
with an R script.
I can't seem to track down R functions to calculate Internal Rate of
Return and NPV? Am I missing something? NPV doesn't seem so difficult
to calculate (at least for a regular series) but I am struggling to
identify how to solve for IRR in R.
It would be sufficient if it worked for a regular series but really
useful if there was something that worked with irregular time series.
cheers
