Detailed Description

Class containing the Data Information.

This Data Set benefits from the comparison to an Excel spread sheet: it can be considered as a Data Frame with a number of rows and a number of columns. The columns will correspond to variables and the rows to samples.

Notes:

For short, this Data Base organization is referred to as Db,
At any time, variables can be added, renamed or deleted,
In the current version, this Data Set is currently limited to numerical contents. The data frame is necessarily completely filled with values: therefore, a specific value stands for a missing value (printed as NA);

Moreover each variable may be assigned a role (or functionality) in the rest of a script. This role is defined by a locator: for example, a variable can serve as a coordinate, or a target variable. The locators can be viewed in the following list (see ELoc.hpp). Note that a variable which does not play any role in particular may be assigned to an idle role (locator NA); This locator may be modified or cancelled (by the user) at any time.

There are two status for these locators: unique or multiple.

Unique. Only one variable can be assigned this unique locator: this is the case for the selection (SEL) as there may be only one current selection activated at a time.

Multiple. Several variable may be assigned the same locator: this is the case for the coordinates (X). In that case, the locator name is followed by its rank (1-based). Then the first coordinate will correspond to the locator X1, the second coordinate to X2, ... Note that:

for a given locator name, the ranks are always consecutive between 1 and N (if it happens that you delete X3, the locator X4 is automatically modified into X3, X5 into X4, and so on up to X{N} into X{N-1}.
there is no limitation in the number of ranks for a given locator name.

Each variable (or column) can be designated:

by its name (unique in the Data Base) or
by its locator (name and rank) or
by its column index (0-based): this designation mode is dangerous (and not recommended) as the index may change over time.

Member Function Documentation

int Db::addColumns	(	const VectorDouble &	tab,
		const String &	radix = `"New"`,
		const ELoc &	locatorType = `ELoc::fromKey("UNKNOWN")`,
		int	locatorIndex = `0`,
		bool	useSel = `false`,
		double	valinit = `0.`,
		int	nvar = `1`
	)

Add one or several columns to an already existing Db. This is performed by providing an array of values 'tab'. Its dimension must be equal to the number of samples (or active samples if 'useSel' is true, times the number of variables 'nvar'.

Parameters

tab	Array to be loaded
radix	Generic name for the newly created variables
locatorType	Generic locator assigned to new variables
locatorIndex	Locator index (starting from 0)
useSel	true if the Selection must be taken into account
valinit	initial value (for unselected samples)
nvar	Number of variables loaded

Returns: Rank of the first UID

Remarks: When 'useSel' is used, you must have a Selection already defined. Then the number; of samples provided in 'tab' must match the number of active samples; When a vector 'tab' is provided, the number of variables 'nvar'; is calculated as its size divided by the number of samples in the grid.

int Db::addColumnsByConstant	(	int	nadd = `1`,
		double	valinit = `0.`,
		const String &	radix = `"New"`,
		const ELoc &	locatorType = `ELoc::fromKey("UNKNOWN")`,
		int	locatorIndex = `0`,
		int	nechInit = `0`
	)

Create a set of new variables in an already existing Db and initialize their contents to a constant value

Parameters

nadd	Number of variables to be added
valinit	Value to be used for variable initialization
radix	Generic radix given to the newly created variables
locatorType	Generic locator assigned to new variables
locatorIndex	Locator index (starting from 0)
nechInit	Number of samples (used only if the Db is initially empty)

Returns: Rank of the first UID

void Db::addColumnsByVVD	(	const VectorVectorDouble	tab,
		const String &	radix,
		const ELoc &	locatorType,
		int	locatorIndex = `0`,
		bool	useSel = `false`
	)

int Db::addColumnsRandom	(	int	nadd,
		const String &	radix = `"New"`,
		const ELoc &	locatorType = `ELoc::fromKey("Z")`,
		int	locatorIndex = `0`,
		int	seed = `1352`,
		int	nechInit = `0`
	)

Create a set of new variables in an already existing Db and initialize their contents as a ranom value (from Normal distribution)

Parameters

nadd	Number of variables to be added
radix	Generic radix given to the newly created variables
locatorType	Generic locator assigned to new variables
locatorIndex	Locator index (starting from 0)
seed	Seed value
nechInit	Number of samples (used only if the Db is initially empty)

Returns: Rank of the first UID

int Db::addSamples	(	int	nadd,
		double	valinit = `TEST`
	)

Add samples to the Data Base

Parameters

nadd	Number of samples to be added
valinit	Default value given to the added samples

Returns: Index of the first newly added sample (or -1 if adding samples is not authorized)

int Db::addSelection	(	const VectorDouble &	tab = `VectorDouble()`,
		const String &	name = `"NewSel"`,
		const String &	combine = `"set"`
	)

Add the contents of the 'tab' as a Selection

Parameters

tab	Input array
name	Name given to the newly created Selection variable
combine	How to combine with an already existing selection (see combineSelection() for details)

Returns: Rank of the newly created Column within the Data Base

Remarks: The Selection is set to True if tab is not zero and to False otherwise.; If the dimension of 'tab' does not match the number of samples in the Db; the action is cancelled (a message is issued)

int Db::addSelectionByLimit	(	const String &	testvar,
		const Limits &	limits = `Limits()`,
		const String &	name = `"NewSel"`,
		const String &	combine = `"set"`
	)

Create a selection around the only defined values of the target variable

Parameters

testvar	Name of the target variable
limits	Limits defining the Definition Domain to be tested (optional)
name	Name of the newly created selection
combine	How to combine with an already existing selection (see combineSelection() for details)

Returns: The rank of the newly created selection variable within the Db

int Db::addSelectionByRanks	(	const VectorInt &	ranks,
		const String &	name = `"NewSel"`,
		const String &	combine = `"set"`
	)

Add a Selection by considering the input 'ranks' vector which give the ranks of the active samples (starting from 0)

Parameters

ranks	Vector of ranks of active samples
name	Name given to the newly created Selection variable
combine	How to combine with an already existing selection (see combineSelection() for details)

Returns

int Db::addSelectionFromDbByConvexHull	(	Db *	db,
		double	dilate = `0.`,
		bool	verbose = `false`,
		const NamingConvention &	namconv = `NamingConvention("Hull", true, true, true, ELoc::fromKey("SEL"))`

Define the Locator(s) for the given variable(s)

Parameters

name	Variable name
locatorType	Locator Type
locatorIndex	Locator Index (for the first variable) (starting from 0)
cleanSameLocator	When TRUE, clean variables with same locator beforehand
