I've just realized that it could be handy to have a 'decreasing' argument in 'is.unsorted'. And I'm cheekily hoping someone else will implement it. It is easy enough to work around (with 'rev'), but would be less hassle with an argument. The case I have in mind uses 'is.unsorted' in 'stopifnot'. Pat -- Patrick Burns pburns at pburns.seanet.com

I suggest that there be an additional sentence in the explanation for the 'repos' argument in the help file for 'install.packages': If the repository is on a local drive, then the string should begin with \code{file:}, e.g., \code{"file:J:/Rrepos"}. Perhaps I'm missing some subtlety, but it makes things work in my case. Pat -- Patrick Burns pburns at

Here's a weird problem that I hope someone can give me some hints for. Actions: Build a package of all R functions -- no compiled code. No indication of anything being wrong. 'require' the newly built package. As far as the session is concerned, there is nothing in the package. This is being done in RStudio on Windows with R version 3.0.2. The package used to work.

It seems like I must be missing something since I haven't been able to find mention of this. Under Windows 7 I'm not getting carriage returns in the output of BATCH files using 2.15.0 (both 64-bit and 32-bit). They are in the startup messages, but not for the real output. Is this on purpose?

Patrick, Thanks. I tried colnames, but it doesn't work. Seems more transformation is needed. But now I got names, that's good enough. Best.

just to add to ted's explanation in case it helps to fix the email server problem: below are the two Recipients and one of the two is always contained in the repeated emails that I'm receiving. Also, of course i don't mean to claim that the names contained in below are doing anything to cause the problem . VEC Operator is just an example. There are 3 or 4 others that repeat

Is there a reason that 'which.min' and 'which.max' don't have an 'arr.ind' argument?

There is a weakness in the 'sample' function that is highlighted in the help file. The 'x' argument can be either the vector from which to sample, or the maximum value of the sequence from which to sample. This can be ambiguous if the length of 'x' is one. I propose adding an argument that allows the user (programmer) to avoid that ambiguity: function (x, size, replace

Hy all, I apologize i've used rownames instead of colnames in my first exemple. (that's why i changed the mail object) I was on mars when i wrote my question... Every answer where correct ... but, because i've made a wrong question, people wern't able to understand... So finally i'm speaking about colnames : Let's be more precise: I've got a query that gives me for
