[R] "welcome" message upon loading data

[Martin Morgan]

Hi Simon --

?data indicates that the first file looked for is mydata.R, and then
mydata.RData and so on. So add a file mydata.R to your data directory that
contains R code to print a message and then loads the data. This hack
is used in Bioconductor, e.g., the Biobase package

http://bioconductor.org/packages/2.0/bioc/html/Biobase.html

to indicated that some data sets are deprecated.
