Question

How can I get the output as a vector in R?

For example, if I want to have

for (i in 1:1000) {if i mod 123345 = 0, a = list(i)}
a

but I would want to find all i that divide evenly into 123345 (i.e., factors), and not just the largest one.

Answer 1

There may be a more concise way to do this, but I would do it this way:

i <- 1:1000
j <- i[12345 %% i == 0 ]

The resulting vector j contains a vector of the values in i which are factors of 12345. In R the modulo operator is %% and it’s a bit of a bitch to find when searching on your own. It’s buried in the help document for arithmetic operators and you can find it by searching for + which must be in quotes like: ?"+" and then you have to read down a bit.

You better add a VBA tag if you want to find a VBA answer. But I suspect it will involve the VBA modulo operator 😉
