Been wracking my brain on how to do this. I first used subset on the capture history to isolate occasions 2:6 (of 7). That was easy. Where I'm falling down is in wanting to restrict the trap locations (and their effects on a multi-capthist) to those with a complete operational history (all usage(trap)==1). Seems like I have to work with the capthist object rather than a traps(capthist) object because removing a "multi" detector has consequences on the capture history. I know I can subset the capture history on trapIDs, but only a handful of the 600+ detectors have incomplete usage profiles. Does the row.number of the traps(capthist) correspond to the index of the trapID in trap(capthist, names=TRUE)? If so, I think I can get at it that way. I must be missing something. Thanks in advance.
