Usage

Hodgkin

Format

A labelled tibble with 40 rows and 3 variables:

Examples

data(Hodgkin)
require(dplyr, quietly = TRUE)
require(sjlabelled, quietly = TRUE)

Hodgkin <- Hodgkin %>%
  mutate(
    Ratio = CD4 / CD8
  ) %>%
  var_labels(
    Ratio = "CD4+ / CD8+ T-cells"
  )

estat(~ Ratio | Group, data = Hodgkin)

Hodgkin %>%
  qq_plot(~ Ratio | Group)

Hodgkin$Ratio <- Hodgkin$CD4 / Hodgkin$CD8
estat(~ Ratio | Group, data = Hodgkin)

qq_plot(~ Ratio | Group, data = Hodgkin)
