In poppr: Genetic Analysis of Populations with Mixed Reproduction

Get a file name and path and store them in a list.

Description

getfile is a convenience function that serves as a wrapper for the functions file.choose(), file.path(), and list.files(). If the user is working in a GUI environment, a window will pop up, allowing the user to choose a specified file regardless of path.

Usage

getfile(multi = FALSE, pattern = NULL, combine = TRUE)

Arguments

multi	this is an indicator to allow the user to store the names of multiple files found in the directory. This is useful in conjunction with poppr.all().
pattern	a regex() pattern for use while multi == TRUE. This will grab all files matching this pattern.
combine	logical. When this is set to TRUE (default), the ⁠$files⁠ vector will have the path appended to them. When it is set to FALSE, it will have the basename.

Value

path	a character string of the absolute path to the chosen file or files
files	a character vector containing the chosen file name or names.
