I want to input a list into a function. But i get the error "Error in +{ :
invalid argument to unary operator". How do I avoid this error?
Here is an example of this problem:
> g = c(2, 4, 8, 16, 32, 64, 128, 122, 110, 86, 38, 76, 18, 36, 72, 10, 20,
40, 80, 26)
> for (i in 1:20)
+ {for (x in 0:20)
+ print(g[i]+x)}

It works for me, without changes. See below.
But I can recreate your error if I type the plus signs at the
beginning of second and third lines. For your example, don't type any
plus signs, except for the one in
print(g[i]+x)}
By the way, nothing that you did fits the description "input a list
into a function", because you haven't created any lists (your
"g" is
not a list).
