[R-sig-eco] Analyzing frequencies in R

Dear list members,

If I have 3 frequencies (3 mutually exclusive groups):

white: 19
black: 43
red: 24

How can I obtain confidence intervals for the proportions, instead of a 
P value from a chisquare test in R?
Or better, how can I assess "effect size" instead of finishing the 
analysis on a P value when analyzing frequencies in R?
Is it possible to obtain standardized Pearson residuals in this situation?
Thank you very much in advance.
Best,

Manuel Spínola
