You need to put parenthesis around (Vector Double). Otherwise

Hi,
let me chime in as someone who wanted to deploy a Haskell app on a
fairly popular hosting environment (Slicehost).
The support of GHC on the Ubuntu server front is tragic - there's no
official Haskell Platform for the currently suggested server version
of Ubuntu, which is Ubuntu 10.04 LTS
Dear all,

Hi,
Data.Map has many great functions, yet I could not find the one that allows
from one map create another map where keys are values and values are keys of
the first one.
Something like:
transMap:: (Ord k, Ord a) = Map k a - Map a k
Does such function exist?
Thanks!

I never set the prefix manually and just use the default. The default
for Windows is $APPDATA/Cabal. Where that ends up depends on your
version of Windows. On Windows --user is also the default.

doctest is a port of Python's doctest[2] to Haskell. It can be used to

provides you with a simple mechanism to write unit test,
Hi David,
thanks for the links. I had a lok at the OO-paper some time ago already,
heard however that its quite unusual and rather tricky to do OO-style
programming in Haskell. So I'm looking for suggestions how to tackle this
problem in a functional way.

That was my (lazy) fault. I saw the name and (faultily) assumed that it
provided functionality on top of another CSV parser.

I've done something perhaps similar in that I have a couple of signal
types, backed by (X, Y) vectors with Y values of different types, but
the same X type. So they can share a fair amount of implementation
that depends only on X. Still more could be shared if I could know a
zero value for each
