Arguments

data

The data as a data frame containing patient timeline information.

patientID

Variable containing unique patient identifiers.

startTime

Time/date when observation/treatment started.

endTime

Time/date when observation/treatment ended.

responseVar

Optional variable for response types (e.g., CR, PR, SD, PD) to color lanes.

timeType

Select whether time values are raw numbers or dates/times.

dateFormat

Select the date/time format in your data (only used when Time Input Type is Date/Time).

timeUnit

Time unit to use for display and calculations.

timeDisplay

Choose whether to align all start times to 0 or use absolute start times.

maxMilestones

Maximum number of milestone events to support.

milestone1Name

Name for the first milestone event (e.g., Surgery, Treatment Start).

milestone1Date

Date/time variable when milestone 1 occurred.

milestone2Name

Name for the second milestone event.

milestone2Date

Date/time variable when milestone 2 occurred.

milestone3Name

Name for the third milestone event.

milestone3Date

Date/time variable when milestone 3 occurred.

milestone4Name

Name for the fourth milestone event.

milestone4Date

Date/time variable when milestone 4 occurred.

milestone5Name

Name for the fifth milestone event.

milestone5Date

Date/time variable when milestone 5 occurred.

showEventMarkers

Whether to display event markers along patient timelines.

eventVar

Variable containing event type labels for markers.

eventTimeVar

Variable containing event times (defaults to start time if not specified).

laneWidth

Width/thickness of patient timeline lanes.

markerSize

Size of event markers and milestone markers.

plotTheme

Visual theme for the swimmer plot.

showLegend

Whether to display the plot legend.

referenceLines

Add reference time lines to the plot for clinical context.

customReferenceTime

Custom time point to mark with a reference line (only used when Reference Lines is set to Custom).

customReferenceDate

When using Date/Time with Absolute display, provide a calendar date (e.g., 2023-06-01) to draw a custom reference line. If left blank, the Custom Reference Time is used as an offset from the earliest start date.

sortVariable

Optional variable to sort patient timelines (defaults to duration-based sorting).

sortOrder

How to order patients in the visualization.

showInterpretation

Whether to display automated clinical interpretation of the timeline data.

personTimeAnalysis

Whether to include epidemiological person-time metrics in the analysis.

responseAnalysis

Whether to analyze response patterns when response variable is provided.

showGlossary

Display a glossary of clinical terms and statistical concepts used in the analysis.

showCopyReady

Generate copy-ready text suitable for manuscripts and clinical reports.

showAbout

Display information about when and how to use swimmer plot analysis.

exportTimeline

Export processed timeline data for external analysis.

exportSummary

Export comprehensive summary statistics and clinical metrics.

Value

A results object containing:

results$instructionsa html
results$plotan image
results$summarya table
results$interpretationa html
results$personTimeTablea table
results$milestoneTablea table
results$eventMarkerTablea table
results$timelineDataan output
