⚠️There's a newer version (0.41.1) of this package.Take me there.

optiRum (version 0.35)

Miscellaneous functions for (primarily) finance / credit risk analysts

Description

This fills the gaps credit analysts and loan modellers at Optimum Credit identify in the existing R code body. It allows for the production of documentation with less coding, replicates a number of Microsoft Excel functions useful for modelling loans (without rounding), and other helpful functions for producing charts and tables. It also has some additional scales for use, including a GBP scale.
