Subject: [R] calculate Euclidean distances between
I want to calculate Euclidean distance between 12 populations, in each
population there are 20 samples and each sample is measured for 100 genes
(these are microarray data; the numbers here are just examples).
The equation I found is:
distance = sqrt{[sum(Average of xi -average of yi)^2] /n
I'd probably start with ?dist

a R package to do it.
Thanks,
