...it can't find the specified weights object "Erro em eval(expr, envir, enclos) : objeto 'W' n?o encontrado" (Error in eval(expr, envir, enclos) : object 'W' not found). The call from within the user-defined function where the error happens is: rReg<-lm(formula=rFormula,data=rData,subset=1:i,weights=W,x=TRUE,y=TRUE) where rFormula is a text string, rData is a 1422 x 17 timeSeries data matrix, both passed from the console, i is a counter, W is a 1422 x 1 numeric vector of weights declared locally within the function. The function definition is as follows: red...

Hi, I am trying to figure out how to get the correlation coefficient for a QQ plot (residual plot). So to be more precise, I am creating the plot like this: qq.plot(rstudent(regrname), main = rformula, col=1) But want to also access (or compute) the correlation coefficient for that plot.
