rtgamma(n, shape, scale=1, a=0, b=Inf)
dtgamma(x, shape, scale=1, a=0, b=Inf)
ptgamma(q, shape, scale=1, a=0, b=Inf)
qtgamma(p, shape, scale=1, a=0, b=Inf)

Arguments

x,q

vector of quantiles.

p

vector of probabilities.

n

number of observations. If length(n) > 1, the length is taken to be the number required.

shape

vector of shape parameters.

scale

vector of scale parameters.

a

vector of lower truncation limits

b

vector of upper truncation limits

Value

dtgamma gives the density, ptgamma gives the distribution function, qtgamma gives the quantile function, and rtgamma generates random deviates.
