Sorry, that is a stupid bug in the blockrand function. I will hunt down the author and slap him upside the head until he fixes it (actually I will probably just raid his freezer and eat his ice cream).
In the mean time there is a simple work around, if you run blockrand like: > blockrand(40, block.sizes=c(4,4)) Then it will force all the block sizes to be 8. Look for a new version of blockrand on CRAN soon with this fixed. ________________________________________ From: r-help-boun...@r-project.org [r-help-boun...@r-project.org] On Behalf Of Ayesha [ayesha.diamond...@gmail.com] Sent: Thursday, January 28, 2010 8:06 PM To: r-help@r-project.org Subject: Re: [R] random permuted block randomization I have tried blockrand but it works in a way that it keeps altering the block size.. like it alternates between 8,6,12. I want a constant block size of 8 :( -- View this message in context: http://n4.nabble.com/random-permuted-block-randomization-tp1401407p1401496.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. ______________________________________________ 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.
