narrow_passes: Identify narrow passes
In jillianderson8/cydr: An R Package for Cleaning Agricultural Yield Data

Description Usage Arguments Value See Also Examples

Adds a column called cydr_NarrowPassError to a dataframe to identify observations associated with narrow passes.

Will identify all observations within narrow passes as erroneous. A pass is deemed narrow if it has an average yield less than 1-diff times that of either its neighbours.

1	narrow_passes(data, remove=FALSE, passColumn=NULL, diff=0.15)

`data`	a dataframe standardized and outputted from AgLeader.
`remove`	a boolean. Defaults to `FALSE`. Indicates whether to remove identified errors.
`passColumn`	a string or `NULL`. Defaults to `NULL`. Indicates what column specifies an observation's pass number. If `NULL` the built-in helper function `number_passes()` will be used to assign pass numbers to each observation.
`diff`	a numeric value between 0 and 1. Defaults to 0.15. Determines the allowable relative difference between neighbouring passes.

A dataframe with an added column called cydr_NarrowPassError. This column will be set to TRUE if it meets the criteria for an erroneous observation.
