Vector operations between grapes: An infix-only package! The 'invctr' functions perform common and less common operations on vectors, data frames matrices and list objects:
- Extracting a value (range), or, finding the indices of a value (range).
- Trimming, or padding a vector with a value of your choice.
- Simple polynomial regression.
- Set and membership operations.
- General check & replace function for NAs, Inf and other values.

Inventory Analytics and Cost Calculations
person("Haytham", "Omar", email = "h.omar5942@gmail.com", role = c("aut", "cre"))
Facilitate  inventory analysis calculations. The package heavily relies on my studies,
the package includes calculations of inventory metrics, profit calculations and ABC analysis calculations.
The first version has only normal and Poisson distributions but I am hoping that other distributions will follow in later versions.
The functions are referenced from :
