xgx_scale_x_time_units: Convert time units for plotting

In xgxr: Exploratory Graphics for Pharmacometrics

Convert time units for plotting

Description

xgx_scale_x_time_units converts x axis scale from one time unit to another. Supported units include hours, days, weeks, months, and years, which can also be called using just the first letter (h, d, w, m, y).

Usage

xgx_scale_x_time_units(
  units_dataset,
  units_plot = NULL,
  breaks = NULL,
  labels = NULL,
  ...
)

xgx_scale_y_time_units(
  units_dataset,
  units_plot = NULL,
  breaks = NULL,
  labels = NULL,
  ...
)

Arguments

units_dataset	units of the input dataset, must be specified by user as "h", "d", "w", "m", or "y"
units_plot	units of the plot, will be units of the dataset if empty
breaks	One of: NULL for no breaks waiver() for the default breaks computed by the transformation object A numeric vector of positions A function that takes the limits as input and returns breaks as output (e.g., a function returned by scales::extended_breaks()). Also accepts rlang lambda function notation.
labels	One of: NULL for no labels waiver() for the default labels computed by the transformation object A character vector giving labels (must be same length as breaks) A function that takes the breaks as input and returns labels as output. Also accepts rlang lambda function notation.
...	other parameters for scale_x_continuous

Details

Note: xgx_scale_x_time_units only scales the plot axis, all other specifications must be on the original scale of the dataset (e.g. breaks, position, width)

Value

ggplot2 compatible scale object

Examples

data <- data.frame(x = 1:1000, y = rnorm(1000))
ggplot2::ggplot(data = data, ggplot2::aes(x = x, y = y)) +
  ggplot2::geom_point() +
  xgx_scale_x_time_units(units_dataset = "hours", units_plot = "weeks")
