Dear DevelopeRs,
I am surprised about the outcome of the second command:
str(as.character(as.numeric("ee")))
str(as.character(log(-1)))
I would have expected a character NA. Is there an intention behind this
behavior?
Best, Ulrike

It seems to me that preserving information about the kind of number

as.numeric(as.character(NaN))
and
as.numeric(as.character(Inf))
both work as the identity operator on numeric-like objects. (In this
context, note that both i

Another message about the R to TeXmacs interface.

The TeXmacs interface allows the user to directly insert graphics into the
session.
Since I am not very familiar with programming for R, I implemented the
interaction with graphics in a very primitive way. It was two modes of

Great. It works m
Kevin,
I wouldn't mind NaN (although it seems a bit strange, because you
wouldn't expect a character to be a number), but I find it strange to
get the character string "NaN". is.na(as.character(NaN)) returns FALSE,
which is what I dislike.
Best, Ulrike

Hi Ulrike
any set of three people will probably have five different opinions on
this, but I can see that this makes sense:
NA - not available, not measured, not recorded
NaN - result of an arithmetic computation that lies outside of the real
numbers; in that sense, "available".
However, th

Hi,
Is there a better approach to adding new slots to an S4 class without
breaking code that accesses older objects of that class than the
Bioconductor reference in the thread below? Thanks.
Cheers,

That thread and the resources in Biobase assumes that you have a class
that extends "Versioned". Doing so will help you in the long run by
providing you with updateObject (at the cost of some complexity).
However, it does not really help you if the existing class does not
extend Versioned.

I found a bug in one of the fourteen speed patches I posted, namely in
patch-vec-subset. I've fixed this (I now see one does need to
duplicate index vectors sometimes, though one can avoid it most of the
time). I also split this patch in two, since it really has two
different and independent parts
