Hi I am new on this forum. I am searching for a function in R which provides all partitions of a set, say for the set {1,2,3} you get {{1,2,3}} {1,{2,3}} {2,{1,3}} {3,{1,2}} {{1},{2},{3}} . The number of partitions of a set is given by Bellsche`s number. The number of possibilities of length (this is the number of subsets included in the partition) of the partition is given by the partition

Hi, I have run rpart to construct a regression tree. Is there any simple method to draw a nice picture of it, as it is usually done in books and paper to visualize the tree?

...directory. Is this already possible? Is it probably difficult to patch rsync to do so? If yes, can the backup option be told to record new/deleted files as well. In that case my aims can be achieved at (much) higher disk space.
