GetFileId {RQDA}R Documentation

Get the ids or names of files list

Description

Get the ids or names of files list.

Usage

GetFileId(condition = c("unconditional", "case", "filecategory"), type =
c("all", "coded", "uncoded","selected"))

GetFileName(fid = GetFileId())

Arguments

condition Any one of "unconditional", "case" or "filecategory".
type Any one of "all", "coded" or "uncoded","selected".
fid integer vector, the id of files.

Details

The imported files are stored in a data base table (called source) in the *.rqda file. Every file in the source table has a unique id. Besides, every file can be assigned to a case or file category.

Given that files meet the condition, the type argument "all" means all files, "coded" means the coded files, "uncoded" means the uncoded files and "selected" means the selected files; in "files" widget, "files of case" widget and "files of category" widget respectively.

GetFileId returns the id of files which fit the combined criterion of condition and type.

Value

Normally, it is a numeric vector of file id. If condition is "case" or "filecategory" but no case or file category is selected, it retuns NULL.
