[R] errores

[Peter B. Mandeville]

Happy New Year to all,

I am using RW0631 and WIN98.

	1. The command DATA only works for the base library. 

	2. The following code on page 312 of Venables and Ripley 1997

sitka.lme <-
lme(size~treat*ordered(Time),random=~1,cluster=~tree,data=Sitka,
serial.structure="ar1.continuous",serial.covariate=~Time)

produced the following error message

Error in lme(size ~ treat * ordered(Time), random = ~1, cluster = ~tree, :
unused argument to function

The example listed on the help for LME worked without problem.

I don't know if my last error reports got out of Mexico or not so here they
are again.

	3. The following code on page 236 of Venables and Ripley 1997 

birthwt.step2 <-
step(birthwt.glm,~.^2+I(scale(age)^2)+I(scale(lwt)^2),trace=F)

produced the following warning message 8 times

Warning: ignored non function "scale"

	4. The following code on page 358 of Venables and Venables 1997 

plot(survfit(leuk.coxs),lty=2:3,lwd=3,add=T,log=T)

produced the following warning message

Warning: parameter "add" couldn't be set in high-level plot() function

Finally, is if possible to automatically load libraries when R is started
and if so how?

Thank you

Peter B.
