Helper Function for the Plot Method of the Data and DataOrdinal Classes

Description

A method that creates a plot for Data and DataOrdinal objects.

A method that creates a plot for Data object.

A method that creates a plot for DataOrdinal object.

Usage

h_plot_data_dataordinal(
  x,
  blind = FALSE,
  legend = TRUE,
  tox_labels = c(Yes = "red", No = "black"),
  tox_shapes = c(Yes = 17L, No = 16L),
  ...
)

## S4 method for signature 'Data,missing'
plot(x, y, blind = FALSE, legend = TRUE, ...)

## S4 method for signature 'DataOrdinal,missing'
plot(
  x,
  y,
  blind = FALSE,
  legend = TRUE,
  tox_labels = NULL,
  tox_shapes = NULL,
  ...
)

Arguments

x	(DataOrdinal) object we want to plot.
blind	(flag) indicates whether to blind the data. If TRUE, then placebo subjects are reported at the same level as the active dose level in the corresponding cohort, and DLTs are always assigned to the first subjects in a cohort.
legend	(flag) whether the legend should be added.
tox_labels	(⁠named list of character⁠) the labels of the toxicity categories.
tox_shapes	(⁠names list of integers⁠) the symbols used to identify the toxicity categories.
...	not used.
y	(missing) missing object, for compatibility with the generic function.

Value

The ggplot2 object.

The ggplot2 object.

The ggplot2 object.

Note

The default values of tox_shapes and tox_labels result in DLTs being displayed as red triangles and other responses as black circles.

With more than 9 toxicity categories, toxicity symbols must be specified manually.
With more than 5 toxicity categories, toxicity labels must be specified manually.

Examples

# Create some data of class 'Data'.
my_data <- Data(
  x = c(0.001, 0.1, 0.1, 0.5, 0.001, 3, 3, 0.001, 10, 10, 10),
  y = c(0, 0, 1, 0, 0, 0, 1, 0, 0, 1, 0),
  cohort = c(1, 1, 1, 2, 3, 3, 3, 4, 4, 4, 4),
  doseGrid = c(0.001, 0.1, 0.5, 1.5, 3, 6, seq(from = 10, to = 80, by = 2)),
  placeb = TRUE
)

# Plot the data.
plot(my_data)
data <- DataOrdinal(
  x = c(10, 20, 30, 40, 50, 50, 50, 60, 60, 60),
  y = as.integer(c(0, 0, 0, 0, 0, 1, 0, 0, 1, 2)),
  ID = 1L:10L,
  cohort = as.integer(c(1:4, 5, 5, 5, 6, 6, 6)),
  doseGrid = c(seq(from = 10, to = 100, by = 10)),
  yCategories = c("No tox" = 0L, "Sub-tox AE" = 1L, "DLT" = 2L),
  placebo = FALSE
)

plot(data)
