| onesidedBias-class {distrMod} | R Documentation |
Class of onesided bias types.
Objects can be created by calls of the form new("onesidedBias", ...).
More frequently they are created via the generating function
positiveBias or negativeBias.
name:"character".sign:"numeric";
to be {-1,1} — whether bias is to be positive or negativesignature(object = "onesidedBias"):
accessor function for slot sign. signature(object = "onesidedBias", value = "numeric"):
replacement function for slot sign.
Class "BiasType", directly.

positiveBias()
## The function is currently defined as
function(){ new("onesidedBias", name = "positive Bias", sign = 1) }
negativeBias()
## The function is currently defined as
function(){ new("onesidedBias", name = "negative Bias", sign = -1) }
pB <- positiveBias()
sign(pB)
try(sign(pB) <- -2) ## error
sign(pB) <- -1
