Re: [R] Can't Destroy Dim Names
Does this help? a = c(one=1,two=2,three=3) str(a) Named num [1:3] 1 2 3 - attr(*, names)= chr [1:3] one two three names(a) = NULL str(a) num [1:3] 1 2 3 For a matrix called mat, you'd need to use dimnames(mat) = NULL to remove the dimnames. But remember that, other than when you're displaying the object, the names or dimnames should not affect anything you do with the object, and they do allow you to index elements by name instead of number. - Phil Spector Statistical Computing Facility Department of Statistics UC Berkeley spec...@stat.berkeley.edu On Tue, 30 Nov 2010, clangkamp wrote: Dear Jim I think the target is to get from a Named chr to a just chr str(mat) Named chr [1:32268] yQAAA jQAAQ UQAAg FQAAw 1QABA ... - attr(*, names)= chr [1:32268] CA CC CG CT ...

Re: [R] Can't Destroy Dim Names
Dear David To confirm, your method worked. I am not allowed to divulge the original data (financial data), but here comes another set. Test_DF-data.frame(Figure=c(A,B,A,B), Code=c(C, C, D, D), No=c(1,2,3.5,4)) ?data.frame View(Test_DF) str(Test_DF) Test_DF_m-melt(Test_DF, measure=No) View(Test_DF_m) Test_DF_c-cast(Test_DF_m, Figure~Code) str(Test_DF_c) Basically, after the casting the variables the naming appears. If one then goes forth with this item, and does some operations on them (in my case with the zoo package), and ends up with the same cube, but just chr as row/column names but actually the same ones and then tries to merge them (abind). The set above doesn't replicate strangely everything my set does, ind adds a lot more attributes even though I go through the same commands. So the bottom line is where I would expect a simple 2 by 2 matrix with row and column names after the melt and cast, it is a much more complex object and I think tearing off all the rest might be a good thing before proceeding. This is the background to the question. - Christian Langkamp christian.langkamp-at-gmxpro.de -- View this message in context: http://r.789695.n4.nabble.com/Can-t-Destroy-Dim-Names-tp876633p3066484.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.
