search for: reexpand

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...

...ind behind the link [1]http://schigold.de/openssh/index.html . I hope you will find it usefull and I'm close to the coding rules. If you want to put my result into one of the next versions, it would have two advantages to me. If my administrator upgrades the ssh, I don't need to reexpand the next version and if you accept my work he will accept this too. If you don't want to accept my patch, please tell me why and if I can do anything for your acceptence, please let me know. If you have questions, please ask me. If you accept it, please let me know the version yo...
