Good afternoon!
I'm trying to model a time series on the following data, which represent a
monthly consumption of juices:
>x<-scan()
1: 2859 3613 3930 5193 4523 3226 4280 3436 3235 3379 3517 6022
13: 4465 4604 5441 6575 6092 6607 6390 6150 6488 5912 6228 10196
25: 7612 72
Hi,
Does anyone know if R has a built-in function that is equvalent to Excel's
percentrank, i.e., returns the rank of a value in a data set as a percentage
of the data set?
Thanks,

Hi R,
I want to do some rolling correlations. But before, I searched for
"?rollingCorrelation" and tried the example in it. But I was not
successful. What could be the problem? Here is the code I tried:

This should do it for you by padding out the rows so they are the same length:

I have been using Aspell on a Linux system, but it doesn't
understand the noweb chunks, which I'd rather it not spellcheck. I
can run it on the generated .tex files, but then changes I make
during the spellcheck will not be propagated back to the original
source. Any suggestions on how to spellchec

Why exactly the same question?
You were told what to do.
I am new to R. I did what the previous poster said.
I found it. Write your function in terms of vector operations. Avoid
loops if you can.
Sample input for R follows
-
# par is the thing that has to be found
# x
I'll throw one more idea into the mix. I agree with Bill that a rating
system for respondents is probably not that practical and of not the highest
importance. It also seems like a recipe for creating inter-personal problems
that the list doesn't need.
I do like Bill's idea of a review system for
I don't think r-help is really intended for packages although for some
very popular packages questions appear on it anyways sometimes.

I don't see one but that means nothing. I think you
can write such a function in a few minutes
Will something like this work or am I

John,
The Excel's percentrank function works like this: if one has a number, x for
example, and one wants to know the percentile of this number in a given data
set, dataset, one would type =percentrank(dataset,x) in Excel to calculate
the percentile. So for example, if the data set is c(1:10), and

Hi all:
Im kind of new on R and I need help changing a table. The thing is, i read a
file on R using the read.table command and the table looks like this:
Item 3d Plot XY plot
001 1 0
001 0 1
001 0
Note that read.table() reads a table and returns a _data frame_. So it is
the _data frame_ that you want to change (a table is something else in R).
This is a simple application of aggregate(), e.g.
> aggregate(z[-1], list(Item=z$Item), sum)
Item X3d_Plot XY_plot
111 2

Its a bit tricky if you want to get it to work exactly the same as
Excel even in the presence of runs but in terms of the R approx function
I think percentrank corresponds to ties = "min" if the value is among those
in the table and ties = "ordered" otherwise so:
percentrank <- function(table, x =
That's no table that's a data.frame :).
For what you want probably the easiest way is
aggregate. Type ?aggregate for the help information
Based on your example and assuming the data is called
"mydata" this shold do what you want.
aggregate(mydata[,2:3], by=list(item=mydata$Item),
sum)

I guess you can get the result by
1) concatenating all the variables (P2_A, P2_B, P2_C) into one variable ,
2) replicating segment membership properly,
3) make the table of 1) and 2)
For example, the following may do the job.
