[Rd] Documentation typos/requests, R1.9.0 beta

[kjetil at entelnet.bo]

I am working with the precompiled rw1090beta as of
2004-03-23.

?ts has in section "See also" 
"Standard package 'ts' for many
     additional time-series functions." td does not longer exist.

?plot.ts 
    example section uses library(ts)

?lines.ts
   example section has library(ts)
