calculating correlation coefficients on repeated measures
Dear list,
I have 9 repeated measures (measurement variable == 'Delta13C') for
individuals (ID variable == 'Individual_ID'. Each repeated measure is
"indexed" (right term?) by the variable 'FeatherPosition' and given as
c('P1', 'P2', 'P3', 'P4', 'P5', 'P6', 'P7', 'P8', 'P9'). I would like
to calculate a correlation coefficient (r) and p.value for all
measures of 'Delta13C' by individual. the function 'cor'...

Identifying records with the correct number of repeated measures
...sampled multiple individuals either 1 or 9
times. Our measurement variable is 'Delta13C' (see below sample
dataset). I cannot figure out how to efficiently use a vector command
(preferably) or a loop to create a new vector of the names of the
individuals sampled 9 times. Note that the 'FeatherPosition' variable
will only be "P1" for individuals sampled only once, while it will be
%in% c('P1', 'P2', 'P3', 'P4', 'P5', 'P6', 'P7', 'P8', 'P9') for
individuals sampled 9 times. In my sample data below the new vec...
