[R] S data sets in R?

[spencerg]

      My favorite tool for finding things like this is 
"RSiteSearch.function" in the "RSiteSearch" package.  For the objects 
you mention, I get the following: 


library(RSiteSearch)
hits(a.s <- RSiteSearch.function("auto.stats")) # 0
hits(sx <- RSiteSearch.function("saving.x"))  # 0
hits(rn <- RSiteSearch.function("rain.nyc1")) # 0
hits(s77 <- RSiteSearch.function("state.x77")) # 12
HTML(s77) # View the 12 and find "states" in the "datasets" package. 

hits(ps <- RSiteSearch.function("Phil Spector"))  # 0

     
      If you are still interested in that book, you might write to the 
author, suggesting he might get more readers by providing a package that 
includes those data sets.  If he were really interested in having more 
readers, he might also include script files providing R scripts for 
working all the examples in the book, as Doug Bates does in the "nlme" 
package, which can be found using "system.file('scripts', 
package='nlme')".  These provide R code to work essentially all the 
examples in Pinhiero and Bates (2000) Mixed-Effects Models in S and 
S-Plus (Springer).  For me, those files made reading that book much 
easier, more pleasant and memorable. 


      Hope this helps.
