Going to Igor after IDL for your data processing needs is like crawling
after you learned to fly. Igor (I have Pro 4.01) does not support
creating temporary data on the fly. In other words, if you are
interested in a subset of something, you must explicitly create a
variable containing the subset. Indeces do not exist, subscripts are not
allowed on the right side of assignment operator - this means, no
processing or re-assigning of subscripts. You have to use a loop to work
on a subscript. Expressions are not allowed in visualization calls, only
variables (so-called waves). Last time I checked, 3D visuals of any size
over a megabyte were so slow on a G4 it was unbearable. No pointers,
structures or objects.
Pros:
Nice 2D visuals with perfect eps output. Point-and-click color,
linestyle, etc - out of the box, no programming. A bunch of built-in
statistical analyses tools, easy to use (if you have the patience to
prepare your sub-arrays that you want to analyze). There is Xop (like a
DLM) support, but of course platform-specific and I think requiring a
developers license.
To sum up, Igor is a visualization package, not (really) a data analyses
tool. Processing efficiency is a lot lower than in IDL. I am responsible
for my words as I re-wrote our own data processing code from Igor into
IDL and gained 2 orders of magnitude performance increase. And our data
sets are relatively small - 10Mb the most.
I still do use Igor, and they do have a PC version that is fully
compatible with Igor for the Mac files. But I use it only to put the
results of IDL processing into nice presentation format.

Cheers,
Pavel
