| distroptions {distr} | R Documentation |
With distroptions and getdistrOption you may inspect and change the global
variables used by package distr.
distroptions(...) getdistrOption(x)
... |
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. |
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() 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.
