Re: [R] Unexpected input in function
Thank you for your responses. You helped me to see something right in front of
me that I should have noticed quickly. I copy/pasted my script from MS Word
instead of using a safer text editor. I did catch the funky double-quotes the
MS Word uses, but I think it also sometimes substitutes a dash for a minus sign.

I think the most likely explanation is that something in
the input string has had the effect of inserting an invisible
"character" between the "-" and the "a" in "b-a", and a
possible suspect is pollution by UTF8: see the discussion at
http://r.789695.n4.nabble.com/unexpected-input-in-rpart-td3168363.html
Or a character "copy&paste"d from an editor that uses a
non-ASCII encoding for its characters. See e.g.:

Re: [R] Unexpected input in function
The OP's error suggests (to me) that there's a line break error
somewhere so it may be a funny quirk of encoding/OS incompatibility if
it's from a source()'d script.
Incidentally, the OP could also write the body of his function as a
one liner with:
seq_along(a) - a

Re: [R] Unexpected input in function
I think you'll need to provide a reproducible example, because your
code works for me:
> fsubt <- function(a) {
+ b <- 1:length(a)
+ b-a
+ }

[R] Unexpected input in function
Hi,
Although the following statements work individually in R, they produce an error
if placed inside a function as below:
fsubt <- function(a) {
b <- 1:length(a)
b-a
}
The error message is:
Error: unexpected input in:
"b <- 1:length(a)
b-"
Any insight would be greatly appreciated.
Thanks,
Jack
