@jreback will the astype() call work here?

[vincentarelbundock]

Cool. I rebased/fixuped for cleaner history. Now using convert_objects

[jreback]

looks good...do you have travis enabled?

[vincentarelbundock]

I didn't, but now I flipped the switch and made a minor push. I dont' have a lot of experience with travis, so I don't know if this will work.

[jreback]

git ci --amend -C HEAD will basically repush the last commit with a new hash, but what you did was fine.....

[jreback]

can you rebase to 1 commit? otherwise seems ready to go

[vincentarelbundock]

done

[jreback]

going to merge in a few.....

side issue

should these types of Data I/O things (which are really remote data readers) as opposed to local data formats
be put in a separate doc section entirely?

maybe Data Readers?

@cpcloud ?

[cpcloud]

That sounds good, what about "Remote Data Access"?

[jreback]

sure.....will throw it in....

[vincentarelbundock]

@jreback the code chunks don't show up in the live docs: http://pandas.pydata.org/pandas-docs/dev/remote_data.html

What did I do wrong?

[jreback]

your directives were code, while we use code-block in the rest of the code. must be a older version of sphinx that wesm builds with; I built locally and worked fine. i just changed them and it worked fine. weird.

fixed here: 19c8874

give a once onver after 5pm est again...thanks!
