Dear list,
When I read some source code, I find lot of place used symbol <<- , e.g.
lastTime <<- newTime;
What is the meaning here?
?"<<-"
See also:
require("fortunes")
fortune("<<-")
Also, I find some method with the name start with dot, e.g.
.RowStandardizeCentered = function(x) {
div = sqrt( rowSums(x^2) );
div[ div == 0 ] = 1;
return( x/div );
}
What is the special meaning for the method name start with a dot?
?ls
Note the argument "all.names".
cheers,
Rolf Turner
