GetFileId: Get the id of files list

Description

Get the id of files list.

Usage

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

Arguments

condition

Any one of "unconditional", "case" or "filecategory".

type

Any one of "all", "coded" or "uncoded".

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.

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, a: every file can be assigned to a case or file category. b: they may be either coded or uncoded. GetFileId return the id of files which fit the combined criterion of a and b. The argument "condition" describe the criterion of a, and "type" describes that of b. When "condition" is "case" or "filecategory", GetFileId returns the id of files associated with the selected case or file category, which means you have to select a case or file category; otherwise the result is NULL.

Examples

GetFileId() ## Id of all files
GetFileId("unconditional","coded") ## id of all coded files.
GetFileId("case","uncoded") ## id of uncoded files for the selected case.
GetFileId("filecategory","all") ## id of all files in the selected file category.
