As usual, you're Duncan. Should have tested it. Thanks for the correction.

Here are two ways:
1. wrap the line in braces:
x <- {....
/...}
That doesn't work. You're probably thinking of the way the parsing of
if versus if/else depends on braces:
if (TRUE) print("TRUE")
else print("FALSE")
is a syntax error, except when wrapped in braces.

2. maybe more awkward in general, but sometimes useful:
x <- `/`(... ,
...)

I'm wondering whether there is a character to let R know to expect more
input for a command on subsequent lines. Here is an example:
test_1.R:
x <- c(1,2,3,4)
/ c(1,2,3,4)
x
R CMD BATCh test_1.R produces test_1.Rout:
x <- c(1,2,3,4)
/ c(1,2,3,4)
Error: unexpected '/' in " /"
Execution halted
test_2.R:
x <- c(1,2,3,4) /
c(1,2,3,4)
x
R CMD BATCh test_1.R produces test_2.Rout:
x <- c(1,2,3,4) /
+ c(1,2,3,4)
x
[1] 1 1 1 1
test_2.R works as expected but test_1.R fails because the "/"
operator is at
the start of line 2 not the end of line 1.
Is the some kind of continuation charater one can include in a script
so R
is expecting input on the next line? For example, in other languages,
"\"
works. Without this, one is forced to break lines carefully in the
middle of
a function, for example, to ensure R is expecting more. Any comments
very
welcome.
Thank you,
Neil.
