constraining correlations
...ould like to somehow constrain all the sibling correlations (twin-sib and sib-sib) to be the same while allowing the twin-twin correlation to be different. Here is some simulated code: set.seed(5) famdata <- matrix(rnorm(400),ncol=4,dimnames=list(NULL,c("Twin1","Twin2","Sib1","Sib2"))) famdata[runif(100)<.2,3] <- NA #20% of sib 1s are missing famdata[runif(100)<.4,4] <- NA #40% of sib 2s are missing cor(famdata,use="pairwise.complete") <R output> Twin1 Twin2 Sib1 Sib2 Twin1 1.00000 0.12027 0....

Plotting question: how to plot SNP location data?
...the colour codes from above (z) and include the exact locations of each SNP. Is it possible to do that using the image-function? Below I have tried to solve the problem using the basic plot function but I cannot include the colors to that plot. How would that be possible? colnames(z) <- c("sib1","sib2","sib3","sib4") rownames(z) <- paste(rep("SNP", 20), 1:20) z.t <- t(z) #snploc$location represents the location of the SNP in the chromosome snploc <- data.frame(SNP=paste(rep("SNP", 20), 1:20), location=c(4.2,5.8,6.9,3,8,7,5,4...
