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.
