Hello All, My algorithm as follows; y <- c(1,1,1,0,0,1,0,1,0,0) x <- c(1,0,0,1,1,0,0,1,1,0)
n <- length(x) t <- matrix(cbind(y,x), ncol=2) z = x+y for(j in 1:length(x)) { out <- vector("list", ) for(i in 1:10) { t.s <- t[sample(n,n,replace=T),] y.s <- t.s[,1] x.s <- t.s[,2] z.s <- y.s+x.s out[[i]] <- list(ff <- (z.s), finding=any (y.s==y[j])) kk <- sapply(out, function(x) {x$finding}) ff <- out[! kk] } I tried to find the total of the two vectors as statistic by using bootstrap. Finally, I want to get the values which do not contain the y's each elemet. In the algorithm ti is referred to "ff". But i get always the same result ; > ff list() > kk [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE Because, my "y" vector contains only 2 elements, and probably all of the bootstrap resamples include "1", or all of resamples include "0". So I can not find the true matches. Can anyone help me about how to be? Thanks. -- View this message in context: http://r.789695.n4.nabble.com/indexing-tp4428210p4428210.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
