In the interest of teaching newbies "how to fish" I will admit that I didn't know this in advance and that what I did was:
install.packages("sos") # which I consider to essential in ones R tool chest of search strategies
library(sos) # actually it's in my .Rprofile
findFn("color matlab hot")
It found dcemri

I only found library(dcemriS4)
in current packages so I loaded it and gave it a shot with the code in the older package help page ... with success.
