poppr (version 2.9.6)

getfile: 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)

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.

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.

Examples

if (FALSE) {

x <- getfile()
poppr(x$files)

y <- getfile(multi=TRUE, pattern="^.+?dat$") 
#useful for reading in multiple FSTAT formatted files.

yfiles <- poppr.all(y$files)

}
