path	character[1] Is the root directory. Default is the value of getwd().
options	character[1] String of options to be passed to tree shell command. Default is "-F --charset=ascii". See the available options with system("tree --help").
linux	logical[1] Default is TRUE and indicates that tree of the Linux SO is to be used. Otherwise, the R native approach will be used.

Details

This function calls tree if it is available is Linux OS. The call is made with system(). Otherwise, a (less sophisticated) R native approach is used.

dir_tree() for an implementation entirely based on R and functional in all SO. Also, dir(), list.files() and list.dirs() can be useful in many circumstances.

Examples

# NOT RUN {
tree()
tree("../")
tree("../", linux = FALSE)

system("tree --help")

tree(system.file(package = "lattice"),
     options = "-F --charset=ascii -L 1")
tree(system.file(package = "lattice"),
     options = "-F --charset=ascii -L 2")

# }
