Why does my for loop delete the column instead of edditing it, using R?

I have the following loop:

info$atod <- 0
i=1
info$atod <- for (i in nrow(info)) {
   if(info[i,1] %in% agents$id) {
     1
   }
}

The goal of the loop is to replace the value of info$atod with 1, if the first column of the row contains a value which can be found in agents$id.

In my output the info$atod column is simply nonexistent and I've no idea why.

Is there an easier way to change the value?

Here is the info file:
