densitr (version 0.2)

dpload: Load a single density profile measurement file (*.dpa) or a directory of *.dpa files.

Description

Loads either a single .dpa file or a list of .dpa files. If dpa.file is specified, it will load a single file. If dp.directory is specified, it will search for all dpa files in that directory (recursively in all subfolders, can be turned off) and return a list of dp files. It will use pbapply to display progress, if loading a directory.

Usage

dpload(dp.file = NULL, dp.directory = "", recursive = TRUE, name = "file")

Arguments

dp.file

A path to a single file, including file name.

dp.directory

A directory with .dpa files.

recursive

Also look for density profiles files in subfolders?

name

Either c("file", "folder"), used for naming of list items. If "file", only file name without the complete path will be used for naming ("00050060"). If "folder", the complete path along with file name will be used to name the dpa objects ("data/0005/00/00050060"). *.dpa ending is removed from the name in both cases.

Value

A dp object or a list of dp objects.

Details

NOTE: for now this function only supports loading density profiles created by the Rinntech Resistograph<U+00AE> resistance drilling device (*.dpa). It was tested to work on files produced by R650-RC drill.

Examples

# NOT RUN {
## load a single file
dpload(system.file("extdata", "00010001.dpa", package = "densitr"))
dp <- dpload(system.file("extdata", "00010001.dpa", package = "densitr"))
## load all files in directory
dp.list <- dpload(dp.directory = system.file("extdata", package = "densitr"))
# }
