Another option is to just generate better error messages automatically, e.g.:

functionality is nice. syntax is weird. I think I would have
preferred an "interpolate" function call.
stop( i("class is `class(pi)` and $pi") )
three typing letters, too, and more logical. most importantly, I wish
we had some form of this in base R from the outset--whatever it is--so

thx, deepayan: how is stopifnot better than
if (!all(...)) stop()
given that we have stopifnot() and I have seen it used often, I think
my two suggestions would make it better.
thx, michael: the %and% and %or% constructs are indeed relics of my
perl background. my own definition is
`%and%`
If all you care about is emulating static type checking, then you can also
accomplish the same thing with lambda.r using type constraints on function
definitions.
e.g.
> f(m) %::% matrix : matrix
> f(m) %as% { m }
> f(as.data.frame(matrix(rnorm(12),nrow=3)))
Error in UseFunction("f", ...) : No

But it does not act nicely. All %anything% constructs have the
same precedence, that of %*%. Hence
x==3 %or% "x is not three"
is parsed as
x == ( 3 %or% "x is not three" )
which is

I think one the HTML templating libraries (whisker or mustache or some such)
provides something not unlike this. Perhaps take a look
Thank you, it does work now indeed. My platform is 32 bit.

I am using a variant of stopifnot a lot. can I suggest that base R
extends its functionality? I know how to do this for myself. this is
a suggestion for beginners and students. I don't think it would break
anything.
first, I think it would be more useful if it had an optional character

Hi Samuel,
WGCNA currently does not support calculations with matrices larger
than the old R limit, and it will take some time to update it to
support the large matrices. Furthermore, WGCNA relies on other
functions (most notably hclust) that would have to be updated as well
to support long vector

Hi Sam,
I assume you mean that correlation for _genes_ (not samples)

unfortunately I don't have access to a Mac big enough to try
