The authors borrowed so much else from C, the semicolon would have been
good too.

I know real R coders will chuckle
I'd say cringe, rather than chuckle. This is going to make you waste a
lot of time some day, when you stare and stare at code like Terry's and
can't figure out what's wrong with it:
zed <- function(x,y,z) {
x + y
+z;
}
The value of the function is +z, not x+y+z, even though the C part of
your brain made you type it that way and reads it as one statement in
the body, not two.

but I've taken to using semicolons
just because it looks better to my eyes and let's my brain know where
I think lines end. True, the language isn't checking for them but it
keeps my typing consistent with the only other language I program in.
(EasyLanguage)
plot(cumsum(T1$PL_SUM) ~ T1$MyDate, typ="l");
lines(cumsum(Z1$PL_SUM) ~ Z1$MyDate, typ="l", col="green");
lines(cumsum(Z2$PL_SUM) ~ Z2$MyDate, typ="l", col="red");
lines(cumsum(Z3$PL_SUM) ~ Z3$MyDate, typ="l", col="purple");
While it's not supported today, maybe one day there could be a way it
was? Who knows...
Cheers,
Mark
