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
end=dim(d)[2]
r=d[,cinit]-d[,st:end]
r2=cbind(r2,r)
}
