plot.hemo: Plot hemo data

In dankelley/hemo: Analysis of health data

Description

Plot hemo data

Usage

## S3 method for class 'hemo'
plot(x, style=c("ts", "clock", "pairs"),
     which, cex=par("cex"), debug=FALSE, 
     show.mean=TRUE, show.lm=FALSE, show.spline=TRUE, ...)

Arguments

x	hemo object, typically result of read.hemo.
style	"ts" for time-series, "clock" for r-theta with angle indicating time of day, or "pairs" for a pairs plot.
which	integer, or list of integers, indicating what is to be plotted; see “Details”.
cex	base symbol size to use; some elements are smaller than this.
debug	boolean flag, set to TRUE to get printout of some things that may help in debuggin the code.
show.mean	boolean flag, set to TRUE to get a ring with mean value. This is only used for clock plots.
show.lm	boolean flag, set to TRUE to get a linear regression added to the plot (with confidence intervals on the prediction).
show.spline	boolean flag, set to TRUE to get a smoothing spline added to the plot. This will have one degree of freedome per month of data, or 2 degrees of freedom if there are fewer than 2 months of data. No spline will be computed unless there are 10 data points.
...	optional arguments passed to plotting functions.

Details

Several plots are available, depending on the values of item, style, and which. Values of which (for item="bp") are as follows.

• which=1 for systolic pressure.

• which=2 for diastolic pressure.

• which=3 for mean arterial pressure.

• which=4 for pulse pressure.

• which=5 for pulse rate.

• which=6 for weight.

• which=7 for cumulative running time (only for style="ts").

• which=99 for statistics (only for style="clock".)

If which is not provided, then the value c(1,2,6) will be used for ts plots, c(1,2,5,7) for clock plots, or c(2,3) for pairs plots.
