Hi, suppose I have a matrix (or dataframe) as a result from subsetting. mat <- matrix(1:20,ncol=2) mat[c(3,6,9),] <- NA cc <- complete.cases(mat) sub <- mat[cc,,drop=FALSE] sub <- sub * 2 #some caluculations with sub. now I would like to expand sub somehow so row 3,6, and 9 would be filled with NAs but the rest should be in place again. Is there a simple function for this?

...ich seems absent for now. Ok, the idea. It seems interesting to try to make lexer a little bit more efficient in terms of macro expanding by applying partial expansion of macros. the idea is that some libraries have rather deeply nested macro definitions, and each time lexer sees it in code, it reexpands definition fully. This seems to be overkill sometimes, for rather often macros are not redefined in code, so expansion can be reused. Of course, the typical nesting is rather low, but for example BOOST_PP_REPEAT can cause such situations. So, the question is, what do you think about possible u...

Hello, in the company I work for we have an ISDN-router is dialing automatic to a special machine if a special IP-address is called by a client-PC inside the company. So we maintain the machines of our customers. But there is one problem: We cannot say to this router "hang up - I'm ready". So he has a configured idle timeout after this time he hang up by himself.
