XPSConstrain function to set fit constraints

Description

XPSConstrain function allows a direct setting of the constraints needed for the best fit of a Core-Line. Generally constraints are set more easily by using the /codeXPSConstraintsGUI() function, a simple and powerful GUI.

Usage

XPSConstrain(
  Object,
  ncomponent = NA,
  action = c("show", "link", "fix", "set", "remove"),
  variable = NULL,
  parameter = NULL,
  value = NA,
  expr
)

Arguments

Object	XPSSample
ncomponent	the fit component index
action	link, fix, set, remove the constraint to apply or remove
variable	h, mu, sigma, etc. the fit parameter to constrain
parameter	one of the values start, min, max
value	the value to set
expr	the constraint expression

Examples

## Not run: 
 XPSConstrain(XPSCoreline[[3]], ncomponent=2, action="link", variable="mu", expr="mu1+1.5")
 XPSConstrain(XPSCoreline[[2]], ncomponent=3, action="link", variable="sigma", expr="sigma1")

## End(Not run)
