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