tx_transmat: Generate a graphical transition matrix.

In johnwilsonICON/TxVis: Visualizations for treatment sequence data

Description

To show the rates at which one sequence passes to the next within a treatment regime. The method uses the corrplot package to

Usage

tx_transmat(txvis, sequences = c(1, 2), nseq = NULL, ...)

Arguments

txvis	An object of class txvis.
sequences	A vector of length two indicating the sequences for which the corrplot will be drawn.
nseq	What is the maximum number of sequences
...	additional arguments to corrplot

Value

A square matrix.

Examples

# Create the txvis object:

hlth_data <- create_txvis(patient   = treat$pat_id, 
                          treatment = treat$treatment,
                          start     = treat$start,
                          end       = treat$end,
                          date_format = "%d%B%Y")

# A simple correlation plot:
tx_transmat(hlth_data, sequences = c(1, 2))

# Some cutomization:
tx_transmat(hlth_data, 
            sequences = c(1, 2), 
            mar = c(2, 2, 2, 2),
            order = "hclust")
