Fit piecewise linear model

Description

Fit piecewise linear model

Usage

fitmodel(dat, alldata = FALSE, textsize = 5, title = "")

Arguments

dat

data.frame output by the prepdata() function

alldata

If FALSE (default), only the final 5 heart rate measurements of each step are used to fit the changepoint model. If TRUE, all data are used.

textsize

# Note, files in this package are gzipped to save space. TCX files exported
# from Garmin Connect or others will not have the `.gz` extension and you
# should not use `gzfile()`.
fname = system.file(file = "extdata/2023-09-15.tcx.gz", package = "ConconiAnaerobicThresholdTest")
x1 <- prepdata(gzfile(fname), startminutes = 23.8, endminutes = 40.1,
         useDeviceSpeed = FALSE)
fitmodel(x1)
