I have a rather large dataset which I just inserted hundreds of interaction terms, and I guess R is saying there is a linear dependence when I run: l1ce(y~., data=x, bound = .5, absolute.t = FALSE).
The error is below: /Error in if (any(bound < 0)) stop("'bound'(s) must be non negative") : missing value where TRUE/FALSE needed In addition: Warning message: In l1ce(poss6 ~ ., data = x, bound = 0.5, absolute.t = FALSE) : X Matrix (transformed variables) has rank 1081 < p = 1086, i.e., is deficient/ Google doesn't show anything regarding the first error. Any ideas what is causing this? Also, how can I find which column vectors have a linear dependence? -- View this message in context: http://r.789695.n4.nabble.com/Error-in-lasso-regression-linear-dependence-issue-tp4630347.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.
