75%-
I now filtered the Na and Inf out of my data.
And the number is exactly the same als the output from the excel file.
Thanks everyone. :)
Now I can finish my work.

Hi
Without data it is only a guess.

I see the problem.
There are 400, but there are Na and Inf is there for like 1/2, and I need to
get those out.
Think I need to filter those out.
Now that would make sense. LoL

Dear R users,
I fear this is terribly trivial but I'm struggling to get my head around it.
First of all, I'm using the "survival" package in R 2.12.2 on Windows Vista
with the RExcel plugin. You probably only need to know that I'm using
"survival" for this.
I have data collected from 180 or so
I found out something strange when I used the same thing on another data
file.
In a excel file I have same data too and there I asked in a certain column
what values where above the 7.5. Result: 206.
Now I have done the same thing in R and I get as result: 400.
My code:
# Find values above 7.
Ahh, I understand -- unfortunately, I'm not aware of an easy way to do
this so you'll have to hack your own: this doesn't look too hard
however, if you call
getAnywhere(predict.Arima)
you can get the prediction scheme R uses. It seems that most of the
heavy lifting is already in C so you'd probab
That is exactly what I was looking for.
Thank you

One solution among many:
seq(970, 970 - 30*14, by=-30)
If you want to be fancy, a function can be easily written:
seqf <- function(startp, lengthv, byv) {
seq(startp, startp + (lengthv - 1)*byv, by=byv)
}
seqf(970, 15, -30)
[1] 970 940 910 880 850 820 790 760 730 700 670 640 610 580 550

You're thinking about it wrong. This is an arithmetic sequence:
seq(from = 1000, by = -30, length.out = 15)

I am trying to integrate this function
f_x(x) = (1/(2pi))*(1+sin(2x)) for o < x < 2
I know the answer is (x/(2*pi))-(cos(2x)/(4*pi)) but I must be doing
something wrong..

I would like to calculate vector from existing value
e.g
v <- 1000
s <- 30
d1<- v-s
d1<- 970
d2<- d1 -s
d2<- 940
d 3 <- d2-s
d3<- 910
:
:
d15 <- .
so how I should get vector of length 15
HI,
x[x>20]
Regards.

Objet : [R] Sort out number on value
Can anyone help me maybe with a question I can seem to find an answer on.
I have this: x = c(1, 5, 70, 53, 7, 29, 75, 37, 3
This really has little to do with sorting, but can be much more easily
done with logical subscripting:
x[x < 20]
which I read as "x such that x is less than 20".
Hope this helps,
Michael
