densitr (version 0.2)

dptrim: Automatically trim an individual density profile on both sides

Description

Calls dpdetect_s and dpdetect_e on a given dp object and returns a trimmed dp object with the the row before the starting point and after the ending removed. If return.plot = TRUE, it will return a plot displaying the dp object with detected starting and ending point. If called with the option return.fail = FALSE and return.plot = FALSE, the returned object will also include information on whether both cutoff points were detected. If starting/ending point not detected, dp object is returned with no changes. When running on a list of dp objects, use dptriml.

Usage

dptrim(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 dtriml or dptriml_s on a dp list with return.fail = 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.

Examples

# NOT RUN {
## load a single dp file
dp <- dpload(system.file("extdata", "00010001.dpa", package = "densitr"))
## trim the measurements
dp.trimmed <- dptrim(dp)
## plot trimming
dptrim(dp, return.plot = TRUE)
# }
