Hi all, ######################################### test=data.frame(x=1:26,y=-23.5+0.45*(1:26)+rnorm(26)) rownames(test)=LETTERS[1:26] attach(test) #test test.lm=lm(y~x)
plot(test.lm,2) identify(test.lm$res,,row.names(test)) # not working plot(x,y) identify(x,y,row.names(test)) # works fine identify(y,,row.names(test)) # works fine identify(x,,row.names(test)) # not working identify(y,,y) # works identify(x,,y) # not working ##################################### My guess is that identify take the object 'x' ( the first argument ) is the thing that on the y axis. However, i have tried many many ways trying to get the LETTERS to be identified in the QQ-plot (plot(test.lm,2)) it never works..... I have even tried to extract the standardized residual using library(MASS), the 'stdres' function, and put it as the first argument in identify, still failed... Is there any means to achieve this?
