Return the median value or the modal value of a vector, depending on whether the vector is numeric or a factor.

centre(x, ...)

# S3 method for numeric
centre(x, na.rm = TRUE, ...)

# S3 method for factor
centre(x, na.rm = TRUE, ...)

Arguments

x	an object for which a method has been defined, or a numeric vector containing the values whose median is to be computed.
...	potentially further arguments for methods; not used in the default method.
na.rm	a logical value indicating whether `NA` values should be stripped before the computation proceeds.

Value

the median value for objects of the class integer or double. The modal value for objects of class factor.

Examples

vec <- c(-3, -2, 0, 1, 1, 3)
centre(vec)
#> [1] 0.5
vec <- c(-3, -2, 0, 1, 1, 3)
vec <- as.factor(vec)
centre(vec)
#> [1] 1
#> Levels: -3 -2 0 1 3
dados <- st_drop_geometry(centro_2015)
#> Error in st_drop_geometry(centro_2015): could not find function "st_drop_geometry"
centre(dados$padrao)
#> Error in centre(dados$padrao): object 'dados' not found
