Dear Amjad

Try these:

#install.packages("fracdiff")
library(fracdiff);

# FYI:

You can simulate ARFIMA this way:

z1<-fracdiff.sim(512,ar=c(0.21,0.2),d=0.3);

#using :

fit<-fracdiff(data1,nar=3,nma=3,h=.Machine$double.eps);   # the last
parameter is some machine dependency
summary(fit);

hope it helps,

Bharat

Look at the documentation for ugarchspec in the rgarch package. The option 'arfima' (TRUE/FALSE) is documented and rather self explanatory.

Do you have the package Rcpp installed?

You need to install certain dependencies (if you do not know how please
ask on the general R help forums).
These include:
Rcpp, RcppArmadillo, numDeriv, chron, Rsolnp, mvtnorm, Kendall, fftw
and can generally be installed with one call from within R,
e.g.
install.packages(c("Rcpp", "RcppArmadillo", "numDeriv", "chron",
"Rsolnp", "mvtnorm", "Kendall", "fftw"))

Depending on the functionality you make use of, more packages might have
to be installed.
