XBRL (version 0.99.19.1)

XBRL: "Mutable state" function that exposes "methods" that analyze an XBRL instance an its associated DTS.

Description

XBRL is a "mutable state" function that offers a object-oriented programming-like interface, by exposing "methods" that perform accions on XBRL files. It keeps a list of data frames that are populated by the "methods" by calls to the low-level functions (see xbrlParse).

The approach used is derived from an example included in *10.7 Scope* of *An Introduction to R*. The employed terminology may be inaccurate, hence the quotations. XBRL "methods" are called by xbrlDoAll. See examples of use below.

Usage

XBRL()

Value

a list of "methods"

Examples

# NOT RUN {
## Setting stringsAsFactors = FALSE is highly recommended
## to avoid data frames to create factors from character vectors.
options(stringsAsFactors = FALSE)

## XBRL instance file to be analyzed, accessed
## directly from SEC website:
inst <- "https://www.sec.gov/Archives/edgar/data/21344/000002134413000050/ko-20130927.xml"

xbrl <- XBRL()
xbrl$setCacheDir("XBRLcache")
xbrl$openInstance(inst)
## Perform a discovery of the taxonomy:
xbrl$processSchema(xbrl$getSchemaName())
## Process instance file:
xbrl$processContexts()
xbrl$processUnits()
xbrl$processFacts()
xbrl$processFootnotes()
xbrl$closeInstance()
xbrl.vars <- xbrl$getResults()
# }
