EdgCMap {cogmapr}

Extract all edges from a Qualitative Data Analysis project

Description

This function opens a Qualitative Data Analysis (QDA) project and extracts edge information.

Usage

EdgCMap(project, sep = ">", coder = "qcoder")

Arguments

project

A QDA project, a list as generated by the ProjectCMap function.

sep

(==Depreciated, with RQDA project==) A character string (often a single character) that is used in RQDA in order to express the relationships between two variables. Default is "_" if codes used in RQDA are of the form : "x_y" (i.e. relationship from x to y), but it is possible to use ">", "->", "–>" or even "—>"

coder

A character string indicating the coding tool used for coding the QDA. The only tool supported now is 'qcoder'. Earlier version of cogmapr worked with "RQDA" project (no more maintened).

Details

The coding used in the QDA have to be done using the 'cogamp-dev' branch of the qcoder package (github : 'FrdVnW/qcoder'). devtools::install_github('FrdVnW/qcoder', ref = "cogmap-dev", upgrade = 'never')

Value

A data.frame with the relationships identified in the interviews. Each relationships ('coding_id') is linked to an agent ('doc_ed'), an edge's name ('edge'), the varible at the origin of the relationships ('concept_from'), the variable at the end of the relationships ('concept_to'), other properties of the relationships ('coding_sign', 'coding_weight', 'coding_class' and 'document_part') and the quotes linked to relationships ('selected_text').

Examples

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

EdgCMap(my.project)
