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

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.

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.

Examples

# \dontrun{

x <- getfile()
#> Error in file.path(file.choose()): unable to translate '<90>k<e4><fe>' to UTF-8
poppr(x$files)
#> Error in poppr(x$files): object 'x' not found

y <- getfile(multi=TRUE, pattern="^.+?dat$")
#> Error in file.path(file.choose()): unable to translate '<90>k<e4><fe>' to UTF-8
#useful for reading in multiple FSTAT formatted files.

yfiles <- poppr.all(y$files)
#> Error in seq(length(filelist)): object 'y' not found

# }
