...ranges from 10 to more than 200. While writing an R-function to display the correlation coefficients between gene A and B in the different tissues as bar-graph, I realized that it may not be correct to compare the different correlation coefficients directly, since the number of samples per tissue varyies between 10 and 200. Thus, the question is: Is there a way to compare different correlation coefficients and/or apply some kind of normalization? Assuming that this might be a well known statistical problem I was browsing statistics books and the web for more information, but could only find the...

...j) would choose ``distant'' parts of the periodic cycle. Unfortunately, we don't know what exactly happens in the S-plus code for set.seed(i), namely, .C("setseed", as.integer(i)) However, I have found out the following which should suffice : 1) Only .Random.seed[4:6] are varyied by set.seed, i.e., after set.seed(i), .Random.seed always is 1 2 3 4 5 6 7 8 9 10 11 12 [1] 21 14 49 * * * 32 22 36 23 28 3 X4 X5 X6 Which means that only the 'congrval' {Venables & Ripley, 2nd ed., p.166-167} is varied 2) X4 is always == 16...
