tx_indiv: Generate an icicle plot for treatment data.

In johnwilsonICON/TxVis: Visualizations for treatment sequence data

Description

Using a txvis object, plot the sequencing of treatments using an icicle plot.

Usage

tx_indiv(txvis, nsample = NULL, aligned = FALSE, clustered = FALSE,
  events = FALSE)

Arguments

txvis	An object of class txvis.
nsample	The number of patients to show sequence data for. Default is 10.
aligned	Should treatment sequences be displayed by date, or from a common origin. Default is FALSE.
clustered	Organize treatments so that similar treatments are adjacent to one another. Not implemented.
events	Should individual events be superimposed onto the treatment sequences. Defaults to FALSE.

Value

Returns a ggplot2 object.

Examples

 hlth_data <- create_txvis(patient        = treat$pat_id, 
                           treatment      = treat$treatment,
                           start          = treat$start,
                           end            = treat$end,
                           date_format    = "%d%b%Y",
                           ev_patient     = events$pat_id,
                           events         = events$event,
                           event_date     = events$start,
                           event_end_date = events$end)
                           
 # Plot without events:                          
 tx_indiv(hlth_data)
 
 # Plot with event data:
 tx_indiv(hlth_data, events = TRUE)
 
 #  Add additional ggplot2 styline:
 library(ggplot2)
 
 tx_indiv(hlth_data) + theme_bw()
 
 # Show many more samples & events, and assign a common start date.
 tx_indiv(hlth_data, nsample = 50, aligned = TRUE) +
   theme(axis.text.y = element_text(size = 8))
