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.
