INVCTR |

This package contains only `infix`

functions
(`grapes-function-grapes`

), most of them shorten the syntax
for common vector operations, such as finding indices and extracting
values from vectors.

The main function classes are:

*Extractors*- Extract indices or values from the front or the rear of a vector*Insiders & Outsiders*- Determine whether values in a vector are inside or outside a specific range and/or exctract those values*Counters*- Automatically increment a value or a numerical object (e.g. in a while loop)*Padders & Trimmers*- Padd or Trim the front and/or rear of a vector*Regressors*- Perform simple polynomial regression on vectors

In addition, some infix functions for very specific tasks are
provided, e.g., *the rose tinted infix* `%00%`

provides a means to deal with functions that return `NA`

,
`Inf`

, `NULL`

or other error/exception values by
turning them into a user specified value.
