unlist(x, recursive=TRUE, use.names=TRUE)
x, unlist
produces a vector which contains all the atomic components
which occur in x.
If recursive=FALSE, the function will not
recurse beyond the first level items in x.
By default, unlist tries to retain the naming
information present in x.
If use.names=FALSE all naming information is dropped.
c, as.list.unlist(options()) unlist(unlist(options(), use.names=F))# works for vectors or lists l.ex <- list(a = list(1:5, LETTERS[1:5]), b = "Z", c = NA) unlist(l.ex, rec = F) unlist(l.ex, rec = T)
