## Financial Functions & More

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.
