Plot13CRecord: Plot a 13C record and fit results

In dmenne/d13cbreath: Reads and Evaluates Gastric Emptying 13C Breath Test Data

Description

Reads record from database and plots raw data, fit, and extracted coefficients

Usage

Plot13CRecord(con, breathTestRecordID, showParameters = NULL,
  ymax = NULL, xmax = NULL, showName = FALSE,
  showPopulationFit = FALSE)

Arguments

con	Open connection to SQLite database; use OpenSqliteConnection to connect.
breathTestRecordID	BreathTestRecordID in database; used in tables BreathTestRecord (primary), BreathTestParameter, BreathTestTimeSeries (foreign).
showParameters	The parameters to display in the graph as a data frame with column Parameter (t50, tlag,GEC) and Method (BreathID, BluckCoward, Maes). If Method is NA, all variants of Parameter are shown. By default, shows all variants of t50.
ymax	Vertical scaling; default of NULL is for autoscaling
xmax	Time axis scaling; default of NULL is for autoscaling
showName	Show full patient name and DOB, initials otherwise
showPopulationFit	If available, show population fit as a red curve. If the single fit fails, and there is a valid population fit, this is always shown.

Value

A ggplot2 graphics object

Plot13CRecord(con,breathTestRecordID)
Plot13CRecord(con,breathTestRecordID, showParameters)
dbDisconnect(con)
