Determine quantiles of a Categorical discrete distribution
quantile() is the inverse of cdf().
## S3 method for class 'Categorical' quantile(d, p, ...)
d |
A |
p |
A vector of probabilites. |

Unused. Unevaluated arguments will generate a warning to catch mispellings or other possible errors. |
A vector of quantiles, one for each element of p.
set.seed(27) X <- Categorical(1:3, p = c(0.4, 0.1, 0.5)) X Y <- Categorical(LETTERS[1:4]) Y random(X, 10) random(Y, 10) pdf(X, 1) log_pdf(X, 1) cdf(X, 1) quantile(X, 0.5) ## Not run: # cdfs are only defined for numeric sample spaces. this errors! cdf(Y, "a") # same for quantiles. this also errors! quantile(Y, 0.7) ## End(Not run)
