[R] help with r package "trip"

[Alice Domalik]

Hi List, 

I'm relatively new to R, so apologies if my question is rather elementary. 
I'm working with some bird tracking data and I would like to calculate the maximum distance traveled from the colony. 
For the maximum distance traveled, I was going to use the function homedist(). However, when I try to use this function I get the following error: 
Error: could not find function "homedist" 
Anyone know why I would get this error? I have been using other functions in "trip" without an issue. Is there an alternative way I can calculate this? 

Thanks in advance for any help!
