as.numeric_factor(x, keepNA = FALSE, sortUnique = FALSE)

Arguments

x

A factor based on numeric values.

keepNA

Keep NA values (TRUE), or remove them (default = FALSE)

sortUnique

Should the unique character values be sorted? (default = FALSE)

Value

A numeric vector with factor levels as names.

Examples


f <- factor(round(runif(10,0,9)))
as.numeric_factor(f)
#> 9 3 6 7 2 9 7 0 5 6 
#> 9 3 6 7 2 9 7 0 5 6 

# Add NAs
f <- factor(c(round(runif(9,0,9)),NA))
as.numeric_factor(f)
#> 6 0 2 3 6 4 4 6 9 
#> 6 0 2 3 6 4 4 6 9 
as.numeric_factor(f, keepNA = TRUE)
#>    6    0    2    3    6    4    4    6    9 <NA> 
#>    6    0    2    3    6    4    4    6    9   NA
