Dear r-helpers, Could you please help me solve the following problem: When I run
require(AlgDesign) trt <- LETTERS[1:5] blk <- 10 trtblk <- 3 BIB <- optBlock(~., withinData = trt, blocksizes = rep(trtblk, blk)) In response to the last command, R complains: Error in optBlock(~., withinData = trt, blocksizes = rep(trtblk, blk)) : object ".Random.seed" not found The documentation of optBlock() in AlgDesign doesn't say that I needed to set .Random.seed. I thought it was initiated automatically at the beginning of a session. What am I missing? > sessionInfo() R version 2.4.1 (2006-12-18) i386-apple-darwin8.8.1 locale: C attached base packages: [1] "grid" "datasets" "stats" "graphics" "grDevices" "utils" "methods" "base" other attached packages: AlgDesign xtable latticeExtra lattice gridBase MASS JGR iplots "1.0-7" "1.4-3" "0.1-4" "0.14-16" "0.4-3" "7.2-32" "1.4-15" "1.0-5" JavaGD rJava "0.3-6" "0.4-14" _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400 Charlottesville, VA 22904-4400 Parcels: Room 102 Gilmer Hall McCormick Road Charlottesville, VA 22903 Office: B011 +1-434-982-4729 Lab: B019 +1-434-982-4751 Fax: +1-434-982-4766 WWW: http://www.people.virginia.edu/~mk9y/ ______________________________________________ R-help@stat.math.ethz.ch 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.
