I have recently started working on a new project where I am studying the life cycle of pine tree lappet moths. I am following the growth of several individuals and taking weekly weights up until the point of pupation. I have previously worked with communities but I have never done any repeated measures on the same individual like this, so I am not sure what is the best approach to look for patterns across individuals. I was thinking of producing graphs showing each individual's weight trend, I also have information on feeding quantity, pupation time and moulting, but I don't know if that can be incorporated to the analyses really.

Any suggestions on how this can be done in R? Or any good papers to start with? Thanks in advance
