In paterijk/RXMCDA: Functions to Parse and Create XMCDA Files

Description Usage Arguments Value Examples

Puts interval values related to categories as a categoriesValues tag in an XML tree written according to the XMCDA standard.

1 2	putCategoriesIntervalValues(tree, categoriesValues, categoriesIDs, mcdaConcept = NULL)

`tree`	Object containing the `XMCDA` XML tree.
`categoriesValues`	A matrix representing a `<categoriesValues>`. Each line of each matrix corresponds to an element of the type "the interval value assigned to category c1 is [x, y]". A line is structured as follows: the first element encodes the index of the ID of category c1 in `categoriesIDs`, the second element encodes the value x and the third element encodes the value y. These elements are named according to the `mcdaConcept` attribute if it can be found.
`categoriesIDs`	A vector containing the categories' IDs.
`mcdaConcept`	A string containing the specific `mcdaConcept` attribute which should be written.

The function returns a list structured as follows:

status

Either OK if all the <categoriesValues> tags could be correctly put, or the description of the error.
