This cannot be correct. The response variable is a vector, while the predictor variables form a matrix. You have the response variable consisting of only the first 8 observations, then all the columns. Perhaps you mean:
X <- crs[,1:8] y <- crs[,9] If this is not the case, please include the output of head(crs) and then tell us which variable is your response. -- Patrick Breheny Assistant Professor Department of Biostatistics Department of Statistics University of Kentucky ______________________________________________ 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.
