indexing using iterator (Frame.ix[#]) changed - .ix does not work, .iloc does
Hi all,

Not sure if this is known or not - couldn't find anything like it in the list of problems.  I use data frames that basically have a column of serial numbers, and then two columns after that that contain multidimensional arrays representing data for each serial number (say md1 and md2). On both pandas 0.13.0 and 0.13.1:

Frame[md1].ix[0]
fails with Exception: Data must be 1-dimensional
but Frame[md1].iloc[0] returns the array as expected.

It seems to work before v0.13.0.  I used it in some loop constructs like:

[ do something with Frame[md1].ix[idx] for idx in Frame.index ]

the workaround is:

[ do something with Frame[md1].iloc[idx] for idx in range(len(Frame.index)) ]

Same happens with md2 column, or anything multidimensional ( I have 3x50 arrays in each md column)

So, I am re-writing a bunch of stuff as I find this error - but I was wondering - is this now how things work and I am "doing it wrong" or have I found a legit bug?

Thanks!
