resolve_intersection(): Compares if two vectors have intersecting values. If TRUE,
removes the intersection values from the base vector
part_of_df(): Check if variable names are part of a data frame. If not, remove them
from the given vector.
remove_doubled_values(): Remove values from a vector that appear more than once.
check_weight(): Check if a weight variable was provided. If TRUE, check whether it
can be used else add a temporary weight variable.
Usage
resolve_intersection(base, vector_to_check, check_only = FALSE)
part_of_df(data_frame, var_names, check_only = FALSE)
remove_doubled_values(var_names)
check_weight(data_frame, var_names)Arguments
- base
The base vector from which to remove any intersecting values.
- vector_to_check
The vector for which intersections should be checked.
- check_only
Returns a list of invalid entries instead of a vector. Additionally it doesn't throw a warning.
- data_frame
A data frame in which to look up variable names.
- var_names
A character vector of variable names.
Examples
# Resolve intersection between two vectors
vec1 <- c("a", "b", "c", "d")
vec2 <- c("e", "f", "a", "g")
vec1 <- resolve_intersection(vec1, vec2)
# Check if variables are part of a data frame
my_data <- dummy_data(100)
var_names <- c("year", "state", "age", "test")
var_names <- my_data |> part_of_df(var_names)
# Remove doubled values
var_names <- c("year", "state", "state", "age")
var_names <- remove_doubled_values(var_names)
# Check the provided weight variable
var_names <- my_data |> check_weight("weight")
