Hi,
perhaps a little bit unusual: is it possible to use - as generic function
with a new signature?
The following example doesn't work:
isGeneric(-)
[1] FALSE
setClass(A,representation(x = numeric))
[1] A
setClass(B,representation(x = numeric))
[1] B
myAssign.A - function(x,value)
+ {
Hello R-experts!
I am using R Version 1.7.1 (2003-06-16) on a Debian Linux box and I
have discovered an odd result when plotting data involving dates. Please
try this minimal example:
a = seq(ISOdate(2000,1,1), ISOdate(2001,1,1), months)
b = 1:13
plot(a,b, col=red)
What I get is a
What are you trying to do with this? Assignment (-) is not a function,
and the language grammar does not convert a - b into -(a, b) (as it
would with the binary operator functions). You could call it that way,
and then it will probably work.

Installing Bioconductor was how it all began, so I ended up doing what you suggested
(in fact I downloaded just the packages I needed as in the full tar ball, rhdf5
wouldn't compile, probably as I don't have the right hdf5 installed but thats not a
problem).
BUT it just bugged me that I

Hi Jason,
I suppose you installed the Matrix library, and it is working on your computer? If
yes, may be det.Matrix() was removed, or renamed in the Matrix library you have (I
cannot check this for the latest version, because I am away of the office until August
1st), but I will do that next

Adding on to this, I think the point is that assignment bypasses the
usual *evaluation* rules, even though it is syntactically a binop.
I think it basically has to be so: For one

I think Brian's question --- what are you trying to do? -- should
be the first order of business.
Someone can make R do just about anything, but it is better to
do a few things very well than lots of things in a muddled way.
So. What is the advantage of using assignment as a generic?

On the SuSE setup I have access to it seems that for whatever reason
the environment variable no_proxy is defined as 'localhost' in the
shell initialization files /etc/SuSEconfig/csh.cshrc and
/etc/SuSEconfig/profile. This turns use of proxy's off in the R
internals. See if you have it defined,
Hello,
I have some data (sar -A -f sar_data.file mydata) that span 24 hours, more or less,
00:00:00 - 23:59:59, or so.
I would like to retain and plot data for all 24 x 60 x 60 = 86,400 seconds. I am able
to set the x coordinates equal
to ISOdate( year, month, day, hour, minute, second)
x0 - ISOdate(2003, 7, 13, 0, 0, 0)
x - x0 + seq(0, 86400)
is what you are asking for, or at least it is in the GMT time zone.
The reason your code is so slow is that expanding vectors by c() is very
wasteful. If you have pre-allocated x and assigned values by indexing I
think it would have
Thank you to everyone who replied to my curious problem, which just got more
curious. Today I closed my copy of R, opened up a different copy of .RData

w/ that for a few minutes. Then closed R again restarted from the copy
I would be grateful for advice about the following problem. It's not
directly R-related, but I'm hoping that R will help me analyse the
following data.
I have a table which indicates the progression of a certain age-related
disease. At a certain point in time, a population was sampled; and I
Perhaps the package msm (Multi-state Markov models in continuous time ) is
interesting for you?
