Re: [R] as.vector with mode="list" and POSIXct

That's a very interesting point, David. The part I actually didn't know is that the class of an object is an attribute, and that by "removing all attributes" the function would in effect unclass it. Thank you. --  Alexandre Sieira CISA, CISSP, ISO 27001 Lead Auditor "

Re: [R] as.vector with mode="list" and POSIXct

now to treat POSIXct values differently. All of a sudden, the POSIXct objects I inserted are being treated, for example, by format as numeric instead of being dispatched to format.Date as expected. So I don't think my reaction to this issue was illogical at all. Hope you'll agree now t

Re: [R] as.vector with mode="list" and POSIXct

POSIXct[1:1], format: "2013-05-21 09:54:11" However, the next thing I need to do is a min() over that list, so I need to convert the list into a vector again. I agree completely with you that this is horrible for performance, but it is a temporary workaround until values() is "fix

Re: [R] as.vector with mode="list" and POSIXct

So it does. I had tried list() but not as.list(). Silly me. :) Thank you very much, William. --  Alexandre Sieira CISA, CISSP, ISO 27001 Lead Auditor "The truth is rarely pure and never simple." Oscar Wilde, The Importance of Being Earnest, 1895, Act I On 20 de maio de 2013 at 18:32:3

[R] as.vector with mode="list" and POSIXct

on(x) {   retval = list()   for (i in 1:length(x)) retval[[i]] = x[i]   return(retval) } Is there a better way to do this (other than using *apply instead of for above) that better leverages vectorization? Am I missing something here? Thanks! --  Alexandre Sieira CISA, CISSP, ISO 270
