Robust Fitting of Univariate Distributions.

fitdstnRob(x, densfun, ...)

`x`	A numeric vector containing the sample.
`densfun`	a character string naming the distribution. Distributions ‘gamma’, ‘lognormal’, and ‘weibull’ are recognized.
`...`	additional arguments are passed to the fitting functions.

a list with class “fitdstn” containing the following elements:

`estimate`	a named numeric vector containing the parameter estimates.
`sd`	a named numeric vector containing the standard deviations of the parameter estimates.
`vcov`	a numeric matrix containing the variance-covariance matrix of the estimated parameter vector.
`mu`	a single numeric value containing an estimate of the mean.
`V.mu`	a single numeric value containing the variance of the estimated mean.
`control`	a list containing the control parameters used by the estimator.
`call`	the matched call.
`densfun`	the character string `densfun` provided in the arguments.
`x`	the data provided in `x`.

The print method displays the estimated parameters and their standard errors (in parentheses).
