pgenlog(q, shape, scale, location)
dgenlog(x, shape, scale, location)
qgenlog(p, shape, scale, location)

`x, q`	vector of quantiles.
`p`	vector of probabilities.
`shape`	shape parameter
`scale`	scale parameter
`location`	location parameter

The functions of the genlog family are a reimplementation of the Generalized Logistic Distribution in the lmomco package, making the code compatible with the standard nomenclature for distribution in R. The original functions in lmomco are pdfglo (density function), quaglo (quantile function) and cdfglo (distribution function).

dgenlog gives the density (pdf), pgenlog gives the distribution function (cdf), and qgenlog gives the quantile function (inverse cdf).
