search for: throwout

Dear all, again i have a problem with special case of dropping lines out of a matrix. i tried the following, where throwout is a vector of length 18 with simple id values that should be compared to any for (k in 1:length(throwout)) { mymatrix=matrix(mymatrix[-(forfact[k]),],ncol=4) } this didnt work and i tried the following to find the error: mymatrix[,1][mymatrix[,1]==throwout[7]] this returned me a nice value...

so here is the code I need help to fix the line for 'st' when it reaches maximum, that's where i am getting stuck. thanks Sharad set.seed(100) d=data.frame(x=rnorm(20)+5, x1=rnorm(20)+5, x2=rnorm(20)+5, x3=rnorm(20)+5, x4=rnorm(20)+5, x5=rnorm(20)+5, x6=rnorm(20)+5, x7=rnorm(20)+5, x8=rnorm(20)+5) r2=c() cinit=0 for (col in 1:9) { cinit=cinit+1 st=cinit+1
