Rui:
It's much simpler than you propose, which is why I left it to the OP.
Just use the results of rle to create a logical vector to index id.
For example, the solution for the OP's example becomes : (d is the
data frame containing id and VI)
> with(d,{
+ z <- rle(VI < 1)
+ vals <- with(z,values
Hello,
Try the following
d <- read.table(text="
id VI
1 -10
2 -4
3 5
4 -2
5 -5
6 -3
7 -2
8 -1
9 4
10 8
", header = TRUE)
fun <- function(n, thres){
r <- rle(!d$VI < thres)
inx <- which(!r$values & r$lengths >= n)
csum <- cumsum(r$lengths)
from <- ifelse(inx == 1, 1, csum[in
z <- rle(VI<1)
gets you most of the way there. ?rle will tell you what z is so that
you can then use it to go the rest of the way.

Hello,
I have 2 variable: one is an "id" sequence from 1:1000 and the other is
variable with real values "VI" from -15.0 to 20.0 and I want to detect id
values that have indicator values less than a certain threshold, for
example (x=1) BUT that are in sequence equal or longer than 5.
For instance
Searching: time series forecasting

Hi
as far as I understand your question it seems to me that
round(5*(1.4^(0:10)))
gives you your sequence
and
cumsum(round(5*(1.4^(0:10
gives you summary sequence.

Two general R tips:
1) Don't name variables seq or var. These are two really important R
functions and you can get all sorts of unexpected craziness if you overload
them. Going forward, also watch out for t,c, T, F as well.
2) As others have noted, it's very possible to implement this without an
I definitely used too much lines s of code because I still don't know how to

seq=5 #starting value
var=5# starting value

var=var+((var/100)*40)

}

A very compact method would be:
cumsum( round(1.4^(0:20)*rep(5, 21)) )
(And I was wrong about it increasing more rapidly if it had been in

It's probably not the most efficient way, but here's
a solution that's not dependent on the grades being sorted:
grade <- c(4,4,4,5,5,7,7,7,7,8,8,8,9,9,9,9,9,10,10,10)
unlist(sapply(rle(grade)$lengths,function(x)seq(1,x)))

Hi Luana,
Try this:
ID <- 1:20

Hello fellows,
I would like to create a sequence for repeated numbers in a dataset. For

Data:
enum.list <- function(x,y) {
mylist <- NULL
for(i in 1:length(x)) {
mylist[[i]] <- x[i]:y[i]
}
xx <- unlist(mylist)

You don't see the standard deviations because
only the final result (the output of summary() in
