In 'system(ls)', 'ls' would be any object, whereas in 'system("ls")', it is a
string. Specifying "quoted string" would be redundant. (True R wizard can
correct me if I,m not accurate.)
When I first encountered R's man pages, I thought they were rather sparse
compared to those of S-Plus. Now I find they are just to the point and so
much easier to consult!
