astonishing memory phenomenon
...s corresponding to 700000*4096/1024/1024 = 2734 MB, which
is impossible given the startup memory, impossible given RAM, impossible
given that no swaping occurs, furthermore the OS (WinNT4) never shows any
additional memory eaten up except that taken at startup.
What's going on?

SQL-Interface
Can anyone give advice how to interactively exchange data between R and
SQL-Databases like DB2, ORACLE, MS-SQL-Server ?
If the answer is: 'currently not', this would be information for me as well.
I will summarize to the list.

polygon() draws non-transparent border, erase.screen draws non-transparent border (PR#1881)
...his
is better than not beeing able to erase the borders at all. However, if border
shall not be erased have
rect(0, 0, 1, 1, col=0, border="tranparent")
instead. Alternatively we could introduce a new parameter border= to
erase.screen(), screen() and split.screen()
