plot.gt1m: Plot accelerometer file

In pawacc: Physical Activity with Accelerometers

Description

Thes functions plot data from Actigraph GT1M and GT3X accelerometer files.

Usage

## S3 method for class 'gt1m'
plot(x, y = NULL, xlab, ylab, main,
keep.error = TRUE, which = "counts", select = 1,...)
## S3 method for class 'gt3x'
plot(x, y = NULL, xlab, ylab, main,
keep.error = TRUE, which = "x", select = 1,...)

Arguments

x	an object of class gt1m. It can be either accfile or acclist.
y	ignored.
xlab	x-axis label (optional).
ylab	y-axis label (optional).
main	main title (optional).
keep.error	logical flag. If FALSE (default) data errors as identified by errorChk will be replaced by NAs.
which	either 'counts' or 'steps' for gt1m files or one of c('x','y','z','steps') for gt3x files.
select	numeric. If class(x) is acclist, this argument specifies the corresponding position of the accelerometer file in the list (first file by default).
...	Arguments to be passed to methods, such as graphical parameters (see par).
