OT: Would you purchase this hardware?
I have about $1200 to spend on 2 boxes and I'd like them to be identical. Very basic web serving, simple HTML5 video, light email serving. Looking around NewEgg, I come across: http://www.newegg.com/Product/Product.aspx?Item=9SIA65C1ZT3064 These use ECC unbuffered RAM which is expensive but I did find 8gb sticks for under $70 each:

dealing with empty actual arguments matched by '...' formals
I'm trying to write some functions to deal with empty actual arguments that are picked up by '...' formals. Such actual arguments are common (and very useful) in calls to subsetting functions, e.g., x[1:2,]. It seems that R and S-PLUS treat these arguments differently: in S-PLUS list(...) will return a list containing just the non-empty arguments, whereas in R list(...) stops

zero.print in print.table after adding margins
The function addmargins() adds margins to a table, but returns a matrix. But even after converted to a table the print.zero="." option of print.table() does not work: > x <- sample( 1:7, 20, replace=T ) > y <- sample( 1:7, 20, replace=T ) > tt <- table( x, y ) > tx <- as.table( addmargins( table( x, y ) ) ) > print( tt, zero.print="." ) y x 1 2
