GetFileId {RQDA} | R Documentation |
Get the id of files list.
GetFileId(condition = c("unconditional", "case", "filecategory"), type = c("all", "coded", "uncoded"))
condition |

type |

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.
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.
