Get the ids or names of files list.

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

getFileNames(fid = GetFileId())

getFiles(condition = c("unconditional", "case", "filecategory", "both"),
         type = c("all", "coded", "uncoded", "selected"), names = TRUE)

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

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.

When condition is "both", the result is intersection of File Id of "case" and "filecategory".

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

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.

getFiles returns a vector of file IDs (with class of "RQDA.vector" and "fileId") when names is FALSE, and a vector of file names ((with class of "RQDA.vector" and "fileName") when names is TRUE.
