Hi, In R-Notes there is the open.account example which is partly kind of what I'd like to do. I would like to add the following properties or capabilities: - I'd like to add persistence to the object. - I'd like to keep an history of all operation done on an account. - I'd like to add the possibility of transfer between accounts and apply the concept of transactions. - I'd like to add multi account management. - I'd like to add reporting capabilities specific to an account or accounts. Since I'm a newbie with R I would probably approach this problem the wrong way. I'm currently using R on a NT box but the reason I'd like to do this using R is because this would enable me to do all the work I want using a single software package (R) and eventually migrate all this under Linux which I'm certain most of you will approuve. So any suggestion would be greatly appreciated. Thanks in advance.
