When calling LM or GLM from within a function, R gives a message error that it can't find the specified weights object "Erro em eval(expr, envir, enclos) : objeto 'W' não 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: redls<-function(rFormula, rData, nStart, rBeta=1., nDelayed=3) I already tried to define W externally to the function and parse it as a parameter, change its name, declare it as an array, declare it as a timeSeries object, with always the same error. Invoking glm instead of lm gives also the same error. The ls.str listing of W immediately before calling lm, showing it does exist, is: W : num [1:1422(1d)] 0.00628 0.0064 0.00654 0.00667 0.00681 ... The exactly same lm call, with the objects created exactly the same way from the console produces no error though. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
