Usage

isColsUniqueIdentifier(dt_data, v_s_cols = NULL)

Arguments

dt_data	a data.table.
v_s_cols	a character vector of column names in dt_data which we expect allow for unique idenfication.

Value

A boolean of whether values in v_s_keys allow for unique idenfication of rows in dt_data.

Examples

library(data.table)
dt_data <- data.table(var1 = c(1,1,2,2) , var2 = c("a", "b" , "a","b") )
isColsUniqueIdentifier(dt_data, v_s_cols = "var1")
isColsUniqueIdentifier(dt_data, v_s_cols = c("var1", "var2"))
