any options can be defined, using name = value or by passing a list of such tagged values.

x

a character string holding an option name.

Value

• distroptions() returns a list of the global options of distr. distroptions("RtoDPQ.e") returns the global option RtoDPQ.e as a list of length 1. distroptions("RtoDPQ.e" = 3) sets the value of the global option RtoDPQ.e to 3. getdistrOption("RtoDPQ.e") the current value set for option RtoDPQ.e.

concept

• global options
• options

Details

Invoking distroptions() with no arguments returns a list with the current values of the options. To access the value of a single option, one should use getdistrOption("WarningSim"), e.g., rather than distroptions("WarningSim") which is a list of length one.

distroptions("RtoDPQ.e") # returns the value of RtoDPQ.e, by default = 5
currentDistrOptions <- distroptions()
distroptions(RtoDPQ.e = 6)
distroptions("RtoDPQ.e") 
getdistrOption("RtoDPQ.e") 
distroptions(c("WarningSim","WarningArith"))   
getdistrOption("WarningSim")   
distroptions("WarningSim" = FALSE)   
         # switches off warnings as to (In)accuracy due to simulations
distroptions("WarningArith" = FALSE) 
         # switches off warnings as to arithmetics
distroptions(currentDistrOptions)
