I have several populations where I have morphology and diet for each individual. I am interested in the correlation between diet and morphological distances. However the number of individuals in each population ranges from 22 to 80 individuals. I have looked at the correlation diet-morphology for each population and (not surprisingly) the correlation coefficientis is highly correlated with the number of individuals per population.
I would like to resample (without replacement) the populations with 60-80 individuals and get random samplings of 30 individuals (1000 times). I would like to get a correlation coefficient distribution against which to test the original value of the correlation.
I guess it is possible do this in R, however I have never written a script in R and I am not familiar with resampling techniques at all. Any help with coding will be greatly appreciated
Thank you Camille
