Frame.to_npz writes partial data when frame has object dtypes

1

**Description** Object dtypes are not supported in `to_npz`, but here is an example where `to_npz` fails as expected, but also writes a partial result to its output file. I think...

From delimited

6

This is a WIP implementation of a `from_delimited_no_guess`, which functions similarly to `from_delimited` but without type guessing. It foregoes `np.genfromtxt`, and instead uses the `csv` module exclusively. Once strings have...

Frame.from_tsv coerces missing data to zero.

2

This may be related to #130, and I assume it's another case of `np.genfromtxt` doing undesired type conversion. ```python f = sf.Frame.from_dict({'A': (10, 20), 'B': (np.nan, np.nan)}) A B

Re-thinking from_delimited

In response to your call for api breaking suggestions, I'd like to suggest a change to the way SF reads delimited text. Namely, I think we should split the *reading*...

dtype conversion with missing values in Frame.from_xlsx

8

When passing dtypes to `Frame.from_xlsx`, missing values seem to be passed to the dtype constructor. This results in the following behavior, where a missing cell is converted to `'nan'`: ```python...

Frame.from_concat should preserve the column order of the first frame, rather than sorting.

When (vertically) stacking frames that have the same columns but different orders, StaticFrame sorts the columns of the resulting frame: ```python f1 = sf.Frame.from_element(1, index=[0], columns=['c', 'a', 'b']) f2 =...

**Description** The behavior of `via_fill_value` with IndexHierarchy is a little strange at the moment. I'm not sure what the right behavior is, as it could be difficult to apply fill_value...

A dataframe with hierarchical columns in where the outer labels are not grouped causes the an error in `to_xlsx_worksheet`. I think it's most easily illustrated with an example: ```python from...

**Description** I'm getting an error when calling `loc_max` on a frame with an index hierarchy. **Example** ```python f = sf.Frame.from_elements([1, 2], index=sf.IndexHierarchy.from_labels([[1, 2], [3, 4]])) # # 0 # #...
