this.path (version 0.5.1)

check.path: Check this.path() is Functioning Correctly

Description

Add check.path("path/to/file") to the beginning of your script to initialize this.path(), and check that this.path() is returning the path you expect.

Usage

check.path(...)
check.dir(...)

Arguments

…

further arguments passed to file.path which must return a character string; the path you expect this.path() or this.dir() to return. The specified path can be as deep as necessary (just the basename, the last directory name and the basename, the last two directory names and the basename, …), but using an absolute path is not intended (recommended against). this.path() makes R scripts portable, but using an absolute path in check.path or check.dir makes an R script non-portable, defeating the whole purpose of this package.

Value

If the expected path / / directory matches this.path() / / this.dir(), then TRUE invisibly.

Otherwise, an error is raised.

Examples

# NOT RUN {
# I have a project called 'EOAdjusted'
#
# Within this project, I have a folder called 'code'
# where I place all of my scripts.
#
# One of these scripts is called 'provrun.R'
#
# So, at the top of my R script, I could write


# this.path::check.path("EOAdjusted", "code", "provrun.R")
#
# or
#
# this.path::check.path("EOAdjusted/code/provrun.R")
# }
