Dear list, I am trying to find the way to add columns to a table (or a matrix) after a loop. The result of this loop is an array and I would like to get all the results in a single table once the loop is finish. I have reproduced a simplified example below:
> a<- 1 > b <- matrix() > while (a <= 4) { + b<-rnorm(10) + a<- a +1 + } # I have tried several methods but without succes so far. > result <- as.data.frame(cbind(b)) > result b 1 -0.03250661 2 -0.59823770 3 1.58120471 4 0.41086546 5 0.78959090 6 1.23587125 7 0.83427190 8 1.09035581 9 0.11331056 10 0.25267231 the result above is not what I am looking for because it shows only the results from the last operation in the loop, I would like to obtain something like the following. > result b1 b2 b3 b4 1 -0.08420826 -0.0637943 -0.83246201 -1.0902384 2 0.40623009 -2.7940096 1.37664973 1.6023967 3 -1.13850505 1.1660669 -0.95962296 -0.7325098 4 -1.06183391 1.1063677 1.67948677 -1.9875475 5 -0.64431067 -0.4843952 -1.30742858 0.5064134 6 0.56729468 1.0860484 0.07651954 0.4380108 7 0.95036177 -0.5328609 1.28954934 -0.2775614 8 -0.17848223 0.5340379 -0.22613700 1.0179886 9 2.93145454 -1.8639607 -0.25478610 1.6619754 10 1.51942415 -0.2051423 0.09144450 -1.6329481 I hope someone can give me a hand best regards a p5.vert.ukl.yahoo.com uncompressed/chunked Sat Aug 12 13:14:00 GMT 2006 ______________________________________________ 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.
