[R] plot history, libraries, weights

[Charles Raux]

3 general questions:
1) How can I have the plot History Recording automatically turned on 
each time I start R (Windows)?
2) How can I have some libraries automatically loaded at R start?
3) As far as I know weights can be specified only for lm. How can I 
take account of weights with a weighted sample in other models or 
functions (table but also other multivariate and cluster techniques)?
Thanks
