Hi
I have a data comprised of repeated measures of growth (5-15 records per individual) for 580 fish (similar to Orange dataset from nlme library). I would like to standardise these growth measures (yi – ŷ/sd) using mean and standard deviation unique to each fish. Can someone suggest a function that would help me do this? I’ve had a look at scale and sweep but can’t find a worked example that does what I’m after

Cheers

John
