Hello, I want to do regression or missing value imputation by knn. I searched r-help mailing list. This question was asked in 2005. ksmooth and loess were recommended. But my case is different. I have many predictors (p>20) and I really want try knn with a given k. ksmooth and loess use band width to define neighborhood size. This contrasts to knn's variable band width via fixing a

How to use sub, gsub, etc. to replace "\" in a string to "/"? For example,convert "C:\foo\bar" to "C:/foo/bar". Thanks, Shengqiao Li

Hi folks, This version added REQ_FLUSH and REQ_FUA support as suggested by Christoph and rebased against latest linus's tree. Jens, could you please consider picking up the dependencies 1/4 and 2/4 in your tree. Thanks! This patchset implements bio-based IO path for virito-blk to improve performance. Fio test shows bio-based IO path gives the following performance improvement: 1) Ramdisk

This is prompted by trying to run the 'inline' package on Mac OS X Leopard = with R 2.10.1. Mac uses completely crazy temp paths and R uses those as wel= l. The inline package creates source files in the temp directory which it t= hen compiles with R CMD SHLIB and attaches. The compilation fails with the = error message below which seems to be caused by the complexity of the path = (compiling the same file with R CMD SHLIB and a sane path is ok, see below)= . What can look like an inline problem, in fact is not inline's as it fails= in exactly the...

This patchset implements bio-based IO path for virito-blk to improve performance. Fio test shows it gives, 28%, 24%, 21%, 16% IOPS boost and 32%, 17%, 21%, 16% latency improvement for sequential read/write, random read/write respectively. Asias He (3): block: Introduce __blk_segment_map_sg() helper block: Add blk_bio_map_sg() helper virtio-blk: Add bio-based IO path for virtio-blk
