## Normal R:
dnorm(0)
## Using the wrapper instead:
p("norm")(0)
### Find the cumulative probability that x<-1 for a Student T distribution, with 20 degrees of freedom.
## Normal R:
pt(-1, df=20)
## Using the wrapper instead:
cdf("t")(-1, df=20)
### For a uniform distribution between 2 and 8, find the value corresponding to the bottom 35% of the data.
## Normal R:
qunif(.35, min=2, max=8)
## Using the wrapper instead:
quant("unif")(.35, min=2, max=8)
### Generate 3 random numbers from a binomial distribution with 5 trials and a .2 success probability.
## Normal R
rbinom(3, size=5, prob=.2)
## Using the wrapper instead:
random("binom")(3, size=5, prob=.2)
