table.n(
  x,
  m = max(x, na.rm = TRUE),
  percentage = FALSE,
  weight = NULL,
  parallel = FALSE
)

Arguments

x: R object with classes
m: maximum number of classes
percentage: boolean. If TRUE result is in percentages.

Examples

x <- c(1,1,2,2,4,4,4)
table.n(x)
#> 1 2 3 4 
#> 2 2 0 3 
# [1] 2 2 0 3
table.n(x, m=5)
#> 1 2 3 4 5 
#> 2 2 0 3 0 
# [1] 2 2 0 3 0
table.n(x, weight=c(1,1,1,2,.5,.5,.5))
#> [1] 2.0 3.0 0.0 1.5
# [1] 2.0 3.0 0.0 1.5
