Usage
concstats_entropy(x, normalized = TRUE, na.rm = TRUE)
Arguments
- x
A non-negative numeric vector.
- normalized
Logical. Argument specifying whether or not a normalized
value is required. Must be either TRUE or FALSE. The default
is TRUE.
- na.rm
A logical vector that indicates whether NA values should
be excluded or not. Must be either TRUE or FALSE. The default
is TRUE. If set to FALSE the computation yields NA
if vector contains NA values.
Value
A single numeric measure.

Examples
# a vector of market shares
x <- c(0.4, 0.2, 0.25, 0.1, 0.05)
concstats_entropy(x, normalized = TRUE)
#> [1] 0.879203
# a vector with NA values
x <- c(0.4, 0.2, 0.25, 0.1, 0.05, NA)
concstats_entropy(x, na.rm = FALSE)
#> [1] NA
