XBRL (version 0.99.17)

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()

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()
# ## End(Not run)
