poppr (version 2.6.1)

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)

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

# NOT RUN {
x <- getfile()
poppr(x$files)

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

yfiles <- poppr.all(y$files)

# Write results to a file in that directory.
setwd(y$path)
write.csv(yfiles)
# }
