## default symbols:

abc(26)
rfree(1,10)


# if we need more than 26:
options(freegroup_symbols=state.name)
rfree(10,4)

# or even:
jj <- letters[1:10]
options(freegroup_symbols=apply(expand.grid(jj,jj),1,paste,collapse=""))
rfree(10,10,100,4)

options(freegroup_symbols=NULL)  #  NULL is interpreted as letters a-z
rfree(10,4)            #  back to normal
