densitr (version 0.2)

dptrim_s: Automatically trim an individual density profile on the starting side

Description

Calls dpdetect_s on a given dpa object and returns a trimmed dpa object with the the rows before the starting point removed. If return.plot = TRUE, it will return a plot displaying the dp object with detected starting point. If called with the option return.fail = FALSE and return.plot = FALSE, the returned object will also include information on whether starting cutoff point was detected. If starting point not detected, dp object is returned with no changes. When running on a list of dp objects, use dtriml_s.

Usage

dptrim_s(dp, return.plot = FALSE, return.fail = FALSE, silent = FALSE, ...)

Arguments

dp

An dp object, see dpload

return.plot

Return a plot instead of dp object? If TRUE, returns a plot instead of a dp object. When return.fail = TRUE, it returns a list of three: dp object, start trimming success and end trimming success.

return.fail

Should information on the success of trimming be included when returning a dp object?

silent

Mute detection warnings, used when calling on list. A list of trimmed dp objects, a result of calling dptriml or dptriml_s on a dp list with rreport = FALSE.

...

Parameters minseglen, span and nroll, will get passed through to dpdetect_s, adjust when profile resolution is not 1/100 of a millimeter.

Value

A trimmed dp object, with the beginning and ending removed, if they were detected. When return.plot = TRUE, it returns a plot displaying the process.

## plot trimming
dptrim_s(dp, return.plot = TRUE)
