generating random samples of IG distribution
Dear R users,
I want to generating random samples from Inverse Gaussian distribution . How can I do? and what package should I install?
Thanks.

How to fit a normal inverse gaussian distribution to my data using optim
...my problem:
I was using optim to estimate parameters of a model and I get this error message
"Error in optim(x0, fn = riskll, method = "L-BFGS-B", lower = lbs, upper = ubs, :
L-BFGS-B needs finite values of 'fn'"
Below is the R code I have written.
library('GeneralizedHyperbolic')
data=read.table(file="MSCI_USA.csv",sep=',',header=T)
data=data[1:8173,]
#starting value
x0 <- c(-0.011,0.146, 0.013, 0.639, 0.059,0.939, -0.144 , 1.187, 1.601, -0.001)
#lower bound and upper bound
lbs <- c(-5, -5, -5, -0.99999, 0.00001, 0, -1,...

http://crantastic.org/packages/DistributionUtils
This package contains utilities which are of use in the packages I
have developed for dealing with distributions. Currently these
packages are GeneralizedHyperbolic, VarianceGamma, and
SkewHyperbolic. Additional packages are under development. Each of
these packages requires DistributionUtils. Functionality includes
sample skewness and kurtosis, log-histogram, moments by integration,
changing the pint about which a moment is calculated, functions for...

Fitting an Inverse Gamma Distribution
http://r.789695.n4.nabble.com/file/n3216865/Inverse_Gamma.png
Hello,
I am seeking help in estimating the parameters of an inverse gamma
distribution (from the 'actuar' package) using a function like 'fitdistr'.
Unfortunately I haven't found such a package using findFn('fit Inverse
Gamma') from the 'sos' package and was therefore hoping someone might be
aware
