Get variable names from a relational data base.

Function to get the names of the variables included in the relational data base.

Usage

dbNames(filePath, includeMeta = FALSE)

Arguments

filePath: Path of an existing .db file.
includeMeta: Should the variable names of the Meta_Data table be included.

Value

Returns a named list of character vectors with the variables names included in the data tables.

Details

Extracts names of all variables included in the relational data base, structured as a list with the individual data tables as elements. The ordering in the list is equivalent to the merge order used when data is pulled from the data base.

Examples

db_path <- system.file("extdata", "example_dataBase.db", package = "eatDB")
varNames <- dbNames(db_path)

## Names of data tables
names(varNames)
#> [1] "NoImp" "Imp"   "PVs"  

## Variable names in data table "NoImp"
varNames$NoImp
#> [1] "ID"     "age"    "weight"
