I need this done in R. Thanks!
I need this done in R programming. Thanks
1. Write a function sumVectors that takes 2 vectors as an input.
Check the types of elements, print a warning if any of the vectors
are not numeric and return "None". Then, check the length of the
vectors. If the lengths are equal, add the vectors and return the
result. Otherwise, print a warning and return "None". Here are a
couple of examples:
> x1 = C(2, 4, 12.5)
> X2 = C(1, 2.5, 7)
> x3 = c(¹1¹, "2",
c('|',
>x4 C(3,0)
า
"3")
> SumVectors (x1₁x2)
[1] 3 6.5 19.5
> Sum Vectors (X1₁ X3)
[1] "one or both numbers are not numeric
NULL
"1
>Sum Vectors (x1₁x4)
[1] "the lengths of both vectors aren't equal"
NULL
