[R] Best-fit linear model for the two matrices plotted.
Hi all.. I am so far successful in plotting the matrices containing r-values and evol.distances using R. But I am facing a problem to fit a line to it. I tried using "lm" function but no success..!! Can you please help me for that? I am giving the functions, I tried, to get a plot here: > dismat <- read.table("M:\dreb5.txt",sep="\t") > cormat <- read.table("M:\cordreb5.txt",sep="\t") > plot(as.vector(as.matrix(cormat)), as.vector(as.matrix(dismat))) > linmod <- lm(cormat~dismat, data=??) <- I am not sure what should be given for the data as two matrices are ploted against each other! Thanking you. Urmi --------------------------------- Get the freedom to save as many mails as you wish. Click here to know how. [[alternative HTML version deleted]]
