I would rather revert the first revision, to honor the effort of the answer and give appropriate context, trying to find the revert button... looks like it doesn't exist.

But you have the revisions to know what was posted. But yes, there are many functionalities that don't exist here and in SO yes... Many of them would be very nice to have, I don't understand why biostar is out of the stackExchange...

You can create nested ifelse statements, for example:

df$new <- ifelse(df$times.x>=1 & is.na(times.y) & times.z==0, 
                 "located.up",
                 ifelse(*some other condition*, 
                        "located.down",
                        ifelse(*some other condition*,
                               "not.located",NA)))
