Package 'cogmapr'

Title: Cognitive Mapping Tools Based on Coding of Textual Sources
Description: Functions for building cognitive maps based on qualitative data. Inputs are textual sources (articles, transcription of qualitative interviews of agents,...). These sources have been coded using relations and are linked to (i) a table describing the variables (or concepts) used for the coding and (ii) a table describing the sources (typology of agents, ...). Main outputs are Individual Cognitive Maps (ICM), Social Cognitive Maps (all sources or group of sources) and a list of quotes linked to relations. This package is linked to the work done during the PhD of Frederic M. Vanwindekens (CRA-W / UCL) hold the 13 of May 2014 at University of Louvain in collaboration with the Walloon Agricultural Research Centre (project MIMOSA, MOERMAN fund).

Type of graph. See detail in RGraphViz. Can be 'neato', 'dot', 'twopi', 'circo', and 'fdp'. The default is 'neato'.
vertex.filter

A vector of integers or characters given the 'id' of vertices (concepts) that will be included in the map. By default, all vertices are included (vertex.filter = NULL)
edge.filter

A vector of characters given the name "i~j" of edges (relationships from "i" to "j") that will be included in the map. By default, all edges are included (edge.filter = NULL)
limit.to.filters

A logical that will impact the position of the vertices. FALSE (the default) will filter vertices and edges (vertex.filter, edge.filter) keeping the position they would have in the unfiltered cognitive map (interesting with background). TRUE will fully re-compute the position of the vertices, building a cognitive map in its own (better readability).
level

0 or 1. Filter the edge/vertices at x level around the filtered edges/vertices (==Not implemented yet==)
size.concepts

Size of the dot linked to vertices
size.labels

Size of the labels of vertices
size.edges

Size of the labels of the weight of edges
size.arrows

Size of arrows (head)
alpha.arrows

The transparency of arrows.
map.color

The unique color of all concepts and labels of the ghost map

Details

A cognitive map where some concepts or relationships are highlighted. The highlighted elements are those who are filtered (see edge.filter, vertex.filter). A background (ghost map) will be show by default. The parameter 'limit.to.filters' can be set as 'TRUE' for only showing the filtered elements.

Value

A plot

Examples

project_name <- "a_new_project"
main_path <- paste0(system.file("testdata", package = "cogmapr"), '/')
my.project <- ProjectCMap(main_path, project_name)
