[R] Sample size multinomial distribution

[SAULEAU EA]

Dear R-users,

I have to estimate several proportions, with a fixed precision, in a
population, modelled by a multinomial distribution. Proportions are not
independent. My problem is to calculate the sample size for this (or these)
precision. Is there any R-programm for doing this? Can I sum each sample
size for each proportion separately? Is there any good paper on this?

Thanks for help,
EAS.
