Hi, Suppose I have: for(i in 1:100000) rnorm(100000) (just a fake example, as my actual example is too long) Is it possible to get the loop to print out i each time it has run? Something like: for(i in 1:100000) { print(i) rnorm(100000) } will only print i after the loop is completed. But if I want to print out i whenever it re-enters the loop, is it possible (so I know how

Hi, Suppose I've got a matrix, and the first few elements look like "x1 + x3 + x4 + x5 + x1:x3 + x1:x4" "x1 + x2 + x3 + x5 + x1:x2 + x1:x5" "x1 + x3 + x4 + x5 + x1:x3 + x1:x5" and so on (have got terms from x1 ~ x14). If I want to replace all the x1 with i7, all x2 with i14, all x3 with i13, for example. Is there an easy way? I tried to put what I want

Hi, I am trying to find out a collinearity in explanatory variables with alias(). I creat a dataframe: dat <- ds[,sapply(ds,nlevels)>=2] dat$Y <- Response Explanatory variables are factor and response is continuous random variable. When I run a regression, I have the following error: fit <- aov( Y ~ . , data = dat) Error in "contrasts<-"(`*tmp*`, value =

I'm looking for a Windows distribution of TeX that works with R, after a few years' absence from Windows. On Duncan Murdoch's Rtools page fptex is still recommended, but it turns out that fptex is "defunct" as of May 2005, see http://www.metz.supelec.fr/~popineau/xemtex-7.html So, what is suggested? TUG (tug.org) recommends something called proTeXt, which is said to be

Hi to all, I am a PH.D Student doing statistical analysis. I am totally new to R. I previously use Stata and am changing into R. I ususally do with logit regression with binary dependent variable (war occurence:1 or 0). I just want to know command to do that. More sepcifically, Let say, my Y is war occurence (occur=1, otherwise 0). And my independent variables (Xs) are trade, democracy,
