Calculate proportion of individuals seen for specific time

Description

Calculate proportion of individuals seen for specific time

Usage

prop_seen(DT, category, ID_unique, time_seen)

Arguments

DT	Data.table with required data
category	Column that inculdes categories for which one wants to calculate the proportion seen (as.character)
ID_unique	Column that inculdes Unique ID by which one wants to calculte the days seen (as.character)
time_seen	Column that inculdes time seen (as.character)

Value

Data.table with category, time_step and proportion seen

Examples

dt = data.table(category  = c(rep('M', 100), rep('F', 100)),
                ID_unique = as.character(c(1:200)),
                time_seen = sample(x = c(1:40), size = 200, replace = TRUE) )

ds = prop_seen(dt, 'category', 'ID_unique', 'time_seen')

## Not run:
