Hi everyone, I've got the following problem:
I've got a matrix [1000,2] and two vectors. In very matrix row there is two coefficients b0 and b1. The vectors are two variables x and y. I want to do a loop to take b0 and b1 and with x and y calculate the residual of a linear model and calculate the second order coefficient of autocorrelation. What I did is : rho<-function(mat, x,y){ rhoes=rep(0,dim(mat)[1]) for (i in 1:dim(mat)[1]){ rhoes[i]=acf(y-(mat[i,1]+mat[i,2]*x),type="correlation",plot=FALSE)$acf[2] #explanation below } print(rho[i]) } I'm getting this error: Error in rho[i] : object of type 'closure' is not subsettable Any help will be deeply appreciated, Cheers, Rafael P.S. mat[i,1]=b0 mat[i,2]=b1 mat[i,1]+mat[i,2]*x= y estimated y-(mat[i,1]+mat[i,2]*x)= errors (residuals) acf= R function to calculate autocorrelation $acf[2] = to extract 2nd order autocorrelation -- View this message in context: http://r.789695.n4.nabble.com/loop-for-error-obj-type-closure-not-subsetable-tp4637873.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
