read.splsm

Import of XML Model Description Specified in SmartPLS

Description

Imports a .splsm file, an XML model description, specified in SmartPLS (see references). Note, that moderator effects specified within SmartPLS are not yet supported. Nevertheless moderating effects can be specified manually.

Usage

read.splsm(file=character(), order=c("generic", "alphabetical"))

Arguments

file

A character naming the path to the .splsm file produced by SmartPLS.

order

A character describing how to order the latent variables (LVs). If

"generic" the LVs will be ordered according to their appearance in the causal chain of the structural model (default).
"alphabetical" the LVs will be ordered alphabetically.

Value

The object returned is of class splsm with the elements:

`connectionIDs`	A `data.frame` containing a source id and target id for all connections of the path model, as specified in the `.splsm` file produced by SmartPLS. The ids refer to the nodes of latent and manifest variable.
`variables`	A `data.frame` containing the names of all the nodes together with their id and x -, y-position on the SmartPLS GUI.
`latent`	A character vector naming the latent variables.
`manifest`	A `character` vector naming the manifest variables.
`path`	Is somehow identical with `connectionIDs`, only that the node ids are replaced by their names.
`strucmod`	Contains only the subset of `path` representing the structural model.
`measuremod`	Contains only the subset of `path` representing the measurement model.
`D`	The adjacency matrix \bm{D} for the structural model.
`M`	The adjacency matrix \bm{M} for the measurement model.
`blocks`	A `list` naming the MVs belonging to each LV's block and telling their measurement mode.
`order`	See armguments section.
