Given > str(x) 'data.frame': 5284 obs. of 5 variables: $ COD : chr "0800101001" "0800101002" "0800101003" "0800101004" ... $ 0-4 : num 79 215 84 58 127 134 15 122 101 99 ... $ 5-9 : num 76 180 32 56 81 106 10 112 128 96 ... $ 10-14: num 68 145 39 46 78 81 8 92 142 107 ... $ 15-19: num 73 170 49 52 103 77 10 116 129 129 ...
I get > str(data.matrix(x)) num [1:5284, 1:5] 8e+08 8e+08 8e+08 8e+08 8e+08 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:5284] "3" "6" "9" "12" ... ..$ : chr [1:5] "COD" "0-4" "5-9" "10-14" ... Should not data.matrix() return a numeric matrix? And I'm even more confused by this: > x2 <- censocatT[,2:5] > str(x2) 'data.frame': 5284 obs. of 4 variables: $ 0-4 : num 79 215 84 58 127 134 15 122 101 99 ... $ 5-9 : num 76 180 32 56 81 106 10 112 128 96 ... $ 10-14: num 68 145 39 46 78 81 8 92 142 107 ... $ 15-19: num 73 170 49 52 103 77 10 116 129 129 ... > str(data.matrix(x2)) num [1:5284, 1:4] 79 215 84 58 127 134 15 122 101 99 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:5284] "3" "6" "9" "12" ... ..$ : chr [1:4] "0-4" "5-9" "10-14" "15-19" Thanks for any clarification Agus -- Dr. Agustin Lobo Institut de Ciencies de la Terra "Jaume Almera" (CSIC) LLuis Sole Sabaris s/n 08028 Barcelona Spain Tel. 34 934095410 Fax. 34 934110012 email: [EMAIL PROTECTED] http://www.ija.csic.es/gt/obster ______________________________________________ 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.
