[Stable]

Helper function to calculate count and fraction of x values in the lower or upper tail given a threshold.

Usage

h_count_cumulative(
  x,
  threshold,
  lower_tail = TRUE,
  include_eq = TRUE,
  na.rm = TRUE,
  .N_col
)

Arguments

x

(numeric)
vector of numbers we want to analyze.

threshold

(number)
a cutoff value as threshold to count values of x.

lower_tail

(logical)
whether to count lower tail, default is TRUE.

include_eq

(logical)
whether to include value equal to the threshold in count, default is TRUE.

na.rm

(flag)
whether NA values should be removed from x prior to analysis.

.N_col

(integer)
column-wise N (column count) for the full column being analyzed that is typically passed by rtables.

Value

A named vector with items:

  • count: the count of values less than, less or equal to, greater than, or greater or equal to a threshold of user specification.

  • fraction: the fraction of the count.

x <- c(sample(1:10, 10), NA)
.N_col <- length(x)

#>     count  fraction

h_count_cumulative(x, 5, lower_tail = FALSE, include_eq = FALSE, na.rm = FALSE, .N_col = .N_col)
#>     count  fraction
