R Documentation

Check MicrobialGrowth arguments (regression function)

Description

Check the arguments passed to the regression function. Tests are generic for all models. For example, the same length for x and y, the type of the different arguments, the values inserted in start, lower and upper, etc. are tested

Usage

.checkMicrobialGrowthArgs(
  x,
  y,
  clip,
  start,
  lower,
  upper,
  nls.args,
  callbackError
)

Arguments

`x`	index series or time series.
`y`	values or list of values to regress (should not be logged).
`clip`	a pair of values indicating in which interval to clip the data `y`. When `clip` is missing, default values are used.
`start`	a named list of starting estimates. When `start` is missing, default values are used.
`lower`	a named list of lower bounds. When `lower` is missing, default values are used.
`upper`	a named list of upper bounds. When `upper` is missing, default values are used.
`nls.args`	additional parameters to use when calling nls.
`callbackError`	function to call on error during regression.

Details

During the check, the clip value is also updated. If the lower bound of clip is -Inf (default value), then this value is replaced by the smallest value greater than zero found in y.
