Suppose you want to set up a list where several consecutive elements take the same value, but you don't want to repeatedly type that value: then use dittolist
to set empty (missing) elements to the previous non-empty element. Wrap in unlist()
to create a vector instead of a list.
ditto.list(...)
# EG:
# ditto.list( a=1, b=, c='hello') # a: 1; b: 1, c: 'hello'
anything, named or unnamed; missing elements OK
List
# NOT RUN {
unlist( ditto.list( a=1, b=, c='hello')) # a: 1; b: 1, c: 'hello'
# }
