| sine_OLS {SCEM} | R Documentation |
Cosine model fitting with proposed initialization.
Description
Performs the updated nonlinear least squares (NLS) regression method for the cosine model (see Chazin et al. 2019).
Usage
sine_OLS(data)
Arguments
data |
A data frame that contains the data for one individual. There should be two columns with names 'distance' and 'oxygen'. |
Value
A fitted model object from the nls function in R:
m |
an 'nlsModel' object incorporating the model. |
convInfo |
a list with convergence information |
data |
the expression that was passed to 'nls' as the data argument. The actual data values are present in the environment of the 'm' component. |
call |
the matched call with several components, notably 'algorithm' |
dataClasses |
the '"dataClasses"' attribute (if any) of the '"terms"' attribute of the model frame. |
control |
the control 'list' used |
