Updated "rfa_ExtractAmax.R" to CRAN Standards

[JasonChiangIB]

Description

Added @return and @description to function Changed function name to ch_rfa_extractamax.R and updated all files accordingly with new name Changed variable names from . to

• Note: was unsure which were R functions and which were variable names, so I only changed things left of the arrow (<--) to be safe

Fixed small typo on rfa_ExtractMMax.R

Please give my changes a quick lookover to see if I'm on the right track. If so, I will start working on other functions as well.

Hi Jason There are some issues with your commit

1. The function needs to have a title line, which needs to be the first line of the function. It looks like you deleted this line. This line is separate from the @description which provides a more detailed description.
2. Your @description and @return lines should begin with capital letters
3. The file has been renamed, but the function hasn't. We need to change the name of the function. This means doing a search in files in Rstudio, for all of the existing function names and changing them to the new ones.

Thanks very much. K
