# set dummy data

set.seed(4)

data = data.frame(date = sample(seq(as.Date("2017-01-01"), as.Date("2018-06-01"), 1), 200, replace = TRUE),
                  sex = factor(c("M", "M", "F", NA, NA), c("F", "M", "Unk")),
                  conf = sample(c("Confirmed", "Probable", "Probable"), 200, replace = TRUE),
                  status = sample(c("Student", "Staff", NA), 200, replace = TRUE),
                  geog = sample(c("South", "North"), 200, replace = TRUE))

# apply function

tab_2vars(data, row.var = "sex", col.var = "conf")

# using dplyr syntax

data %>%
select(sex, conf) %>%
  tab_2vars()
