I am writing to ask if R has a build- in function to calculate this polylogarithm Li_n(z) function , also known as the Jonqui?re's function defined as Li_n(z)=sum_(k=1)^infty(z^k)/(k^n) Thanks Andy

There is an R package 'gsl' which is a wrapper for the GNU Scientific Library, and the GSL includes the 'polylog' function (and many many other special functions).
