Dear R-users,
i have two questions :
1- first of all, i wish to know the way to obtain a serie with a format
like 00 : ( 01,02,03,04) or like postal code
(01100,0).
for instance, i do :
format(strptime(as.character(c(1:4)),%H),%H)
but it sounds complicate and not really efficient!
in order to generate your series, maybe :
format(seq(ISOdate(2003,1,1, 0, 0, 0, tz=), by=min,
length=1440),format=%H:%M)

Dear Brian,
You have to call Rterm.exe *from a command shell*. `cygwin' is not a

For row or column means with a matrix of any size, you will be much
better served by using

colMeans()

Hi there,
I just wanted to take a quick second to thank everyone who maintains this
service- just in case you don't hear it enough, there are a plethora of people
who rely on this service (as evidenced by the help archives), and even if they
don't say it, are greatly thankful for what you do
May I add to Michael's comment:
1) There is no formal service; the R Core team members and other regular
contributors who do yeo-persons' service do so entirely voluntarily and at their
individual discretion..
2) The whole cultural/sociological phenomenon of R strikes me as remarkable.

1. Don't use t as a variable name. It is the name of the
matrix transpose function. In most but not all contexts, R is smart
enough to tell whether you want the system function or the local object.

Any orthogonal transformation preserves angles between vectors and
their length. Therefore, I guess shape and size are preserved -- of
course a precise answer depends on how you define these two features
of a curve.
I am missing what has all this to do with R, though.

You can use assign(), but why do you want to do this? Also, a function
