I'm observing odd behavior of the rep(...) procedure when using variables as parameters in a loop. Here's a simple loop on a vector 'branches' that is c(5,6,5,5,5). The statement in question is print(c(ni,rep(i,times=ni)))
that works properly first time through the loop but the second time, when branches[2] = 6, only prints 5 values of i. Any ideas, anyone? iInd = 1 for(i in 1:length(branches)) { print((1:branches[i])+iInd-1) # iInd is a position shift of the index ni = branches[i] print(i) print(ni) print(c(ni,rep(i,times=ni))) # ... some interesting other stuff for my project that gets wrecked because of this issue iInd = iInd + branches[i] } # first pass through loop [1] 1 2 3 4 5 # branches[1] + iInd - 1 content [1] 1 # i value to repeat 5 times [1] 5 # ni = 5 on 1st pass [1] 5 1 1 1 1 1 # five values - 1 1 1 1 1 - OK # second pass through loop [1] 6 7 8 9 10 11 # branches[2] + iInd - 1 content [1] 2 # i value to repeat 6 times [1] 6 # ni = 6 on 2nd pass [1] 6 2 2 2 2 2 # 6 'twos' but only shows 5 'twos' print(c(ni,rep(i,times=ni))) - why not 6? -- View this message in context: http://n4.nabble.com/Funny-result-from-rep-procedure-tp1560547p1560547.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.
