Subject: Re: [R] copyING directories and files

What about this as a start :

dir.copy <- function( source = getwd(), target ){
    
    files <- list.files( source, recursive = TRUE )
    dirs  <- unique( gsub( "/[^/]+$", "", files[grepl("/", files)] ) )
    
    if( !file.exists( target ) ){
        dir.create( target )
    }
    
    for( d in dirs){
        dir.create( file.path( target, d) , recursive = TRUE )
    }
    for( f in files ){
        file.copy( file.path(source, f) , file.path( target, f ) )
    }
    invisible(NULL)
}


# what I am copying :
> system( "tree" )
.
└── bar
    ├── blabla.txt
    ├── bla.txt
    └── foobar
        └── blabla.txt

2 directories, 3 files

> dir.copy( getwd(), "/tmp/target" )
> system( "tree /tmp/target" )
/tmp/target
└── bar
    ├── blabla.txt
    ├── bla.txt
    └── foobar
        └── blabla.txt

2 directories, 3 files
