In datamatrix[, "y"] == datamatrix[, "y"][-1] : longer object length is not a multiple of shorter object length
out = c(FALSE,datamatrix[,'y'] == datamatrix[,'y'][-1]) and I do not know why I get that error, the resulting out matrix is somehow one row larger than datamatrix... all I try to do is filter matrix by dropping rows where [,'y'][-1] == [,'y'][+1] -- View this message in context: http://r.789695.n4.nabble.com/longer-object-length-is-not-a-multiple-of-shorter-object-length-tp3077400p3077400.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.
