How to rank matrix data by deciles?
Hi R users,
I have a matrix of data similar to:
> y=matrix(rnorm(55),ncol=5)
I would like to know to which decile each number belongs compared to the
numbers in its column.
Say y[1,1] is the third decile among y[1:11,1] and y[2,1] is in the second
decile
I would like get a matrix that would return their ranks in decile, i.e.,
y[1,1] -> 3
y[2,1] -> 2
Your help is much appreciated!

exces return by mktcap decile for each year
I have a data frame, lets call it dat,
with 3 columns ( mc, yr, ret) which represent market
cap, year, and return. mc is a factor, mc, and ret are
real numbers.
I want to add a column to the data calculated as
follows.
For each year, I want to split the data by mc decile,
then calculate the mean ret within that mc decile, and
finally subtract that year's decile mean from the raw
return. Then

Decile
Hello comunity,
I'm trying to find a similar function as decile of SPSS, NTILES (10)
some of you know about that, I will appreciate your help in advance.
In SPSS
VARIABLES=Sales (A) /NTILES (10) /PRINT=NO
for example if I have Next data input:
case IdCust Sales Profit 1 265 140.81 314.31 2 266 1778.96 408.32 3 267
2663.66 820.85 4 268 2994.14 913.73 5 269 2185.58 686.64 6 271 105.21

getting a title in a plot during an lapply
In my code below tempa and tempb are numeric vectors that I combined
into a dataframe along with the deciles of tempa.
I have an lapply statement that goes through the dataframe and does ten
plots according to the appropriate decile.
The code is below and it works fine. There are no bugs so I figure there
was no need to include structure statements on the data.
Also, I don't want to use coplot

french secondary boxplot
bonjour,
i'm a mathematic teacher and i have a question for R-developers :
is it possible to have (in the future) a boxplot with whiskers from
the first decile to the ninth decile, as usual in secondary french
schools... by example : boxplot(serie,range=-1) for french boxplot ?

using weighted.mean with tapply()
I am trying to calculate the weighted mean for a of 10 deciles and I
get an error:
> decile <- tapply(X=mat$trt1m, INDEX=mat$Rank, FUN=weighted.mean, w=mat$mcap)
Error in FUN(X[[1]], ...) : 'x' and 'w' must have the same length
All three of my inputs have the same length, as shown below, and the
weighted.mean calculation works by itself, just not in tapply()

Plotting question
I am constructing plots ( regular not lattice ) and my initial command
is
par(mar=c(3,4,2,2), mfcol=c(5,2))
and then I create 10 plots on the page. It looks great but the plots on
the page go in the order
1 6
2 7
3 8
4 9
5 10
Where the numbers denote decile breakdowns.
Is there an easy way to make them go from left to right so

Deciles and R
Hi everyone,
I'm a new R user (if this is a really basic question, please do excuse
me...) and I'm having some questions regarding a deciles problem.
I have a variable which I need to categorize according to its deciles (X).
However, this categorization should be made into another variable (call it
NewVar).

How to use ggplot to do the binned quantile plots(one type of scatter plot)?
Hi all,
I have done scatter plot: plot(x, y).
Now I wanted to do binned quantile plots... can ggplot2 help me?
For example, we bin x data into 10 bins.
For each bin, we draw the 10 deciles of the corresponding y data in that
bin as points/dots.
And then accross all bins, we would like to connect the corresponding

program and comment
Hi. I am a newbie to R. I need to do a courses
projects with some manipulation lots of data record
and some back-and-forth linear regression. I do not
want to spend $100 for a SAS lincence, which professor
used. So I decide to start to learn R to finish it.
I am using R in Windows. I feel it is somehow works
like mathemica. I try to write the work into a little

How to strip one term from a data.frame? + How to write long line in script?
I need to run a regression with 14 normal variables
and 20 dummy variables. All the data is in a huge
data.frame df. But there is some extra intermediate
item in the same data.frame too. It will be nice I
can strip off those terms and run lm(). Also, is
there a simple way to write the formula, for example,
just specify the y term, all other term in data.frame
should be x_i. Or is there some

Data manipulation query
Hi,
Not sure if I am making a simple problem complex but still here
we go:
I have a data frame with four columns say, X1 X2 X3 and X4. I
want to break X4 into deciles and for each deciles obtained, I want to
see corresponding elements of X1.
Ideally, the output should be in a tabular fashion as shown
below:
Deciles 1 Deciles 2 .... Deciles 10
X1-1 X1-2 X1-99
X1-5 X1-3

alternative to logistic regression
You can fit a linear probability model with glm and a bit of arm twisting.
First, make your own copy of the binomial function:
> dump('binomial', file='mybinom.R')
Edit it to change the function name to "mybinom" (or anything else you
like), and to add 'identity' to the list of okLinks.
Source the file back in, and use mybiom('identity') to fit

general help on R and factor in R and a few simple comment from a newbie
Hi. I am starting to learn R for a course project. I
am relative OK c++ programer. I found the R is very
different. I have read the "an introduction to R". I
have to say it is not very newbie friendly. It does
not explain many things clearly. And unfortunately,
there is not too much introductory materials available
on-line. I do not want to buy a book.
