fips.base.Structure2D#

class fips.base.Structure2D(data, name=None, index=None, columns=None, dtype=None, copy=None, sparse=False)[source]#

Base class for 2D structures (Matrix).

Parameters:

data (np.ndarray) – 2D data.
name (str, optional) – Name for the Structure.
index (pd.Index) – Index for the rows of the DataFrame.
columns (pd.Index, optional) – Index for the columns of the DataFrame. If None, uses the same as index.
dtype (data type, optional) – Data type to force.
copy (bool, optional) – Whether to copy the data.
sparse (bool, default False) – If True, store the data in pandas sparse format (fill_value=0.0). The caller is responsible for zeroing out near-zero values before setting sparse=True (e.g. via a threshold in the builder).

Attributes

`columns`	Return the columns of the underlying DataFrame.
`data`	The underlying data, which must be numeric and non-NaN.
`is_sparse`	True if the internal DataFrame uses pandas sparse storage.
`name`	Name of the structure, used for error messages and block naming.
`values`	Return values as numpy array or sparse matrix.

Methods

`to_dense`()	Return a copy with dense internal storage.
`to_frame`()	Get the underlying DataFrame data.
`to_sparse`([threshold])	Return a copy with sparse internal storage.
