Plot the distribution of follow-up time

plotFollowUpDistribution(
  population,
  targetLabel = "Target",
  comparatorLabel = "Comparator",
  yScale = "percent",
  logYScale = FALSE,
  dataCutoff = 0.95,
  title = NULL,
  fileName = NULL
)

Arguments

population

A data frame describing the study population as created using the createStudyPopulation function. This should at least have these columns: treatment, timeAtRisk.

targetLabel

A label to us for the target cohort.

comparatorLabel

A label to us for the comparator cohort.

yScale

Should be either 'percent' or 'count'.

logYScale

Should the Y axis be on the log scale?

dataCutoff

Fraction of the data (number censored) after which the graph will not be shown.

title

The main title of the plot.

fileName

Name of the file where the plot should be saved, for example 'plot.png'. See the function ggsave in the ggplot2 package for supported file formats.

Value

A ggplot object. Use the ggsave function to save to file in a different format.

Details

Plot the distribution of follow-up time, stratified by treatment group.Follow-up time is defined as time-at-risk, so not censored at the outcome.
