I have one problem with figures.
I draw the Relative Distribution graph,
it looks like barchart(X,Y plot),
but I have ten(year) Relative Distribution grapgs,
have any command am can combine ten barcharts(X,Y plot) to become a three

Help me improving my code
Hi,
I am new to R. My problem is with the ordered logistic model. Here is my
question:
Generate an order discrete variable using the variable
wrwage1 = wages in first full calendar quarter after benefit application
in the following way:
*
wage*1*Ordered *=
1 *if*0 *· wrwage*1 *< *1000
2 *if*1000 *· wrwage*1 *< *2000

How to make a lagged variable in panel data?
Suppose we observe N individuals, for each of which we have a
time-series. How do we correctly create a lagged value of the
time-series variable?
As an example, suppose I create:
A <- data.frame(year=rep(c(1980:1984),3),
person= factor(sort(rep(1:3,5))),
wage=c(rnorm(15)))
> A
year person wage

How might one write this better?
I am trying to simulate the trajectory of the pension assets of one
person. In C-like syntax, it looks like this:
daily.wage.growth = 1.001 # deterministic
contribution.rate = 0.08 # deterministic 8%
Wage = 10 # initial
Asset = 0 # initial
for (10,000 days) {
Asset += contribution.rate * Wage

problem with "dynformula" from "plm" package [RE-POST]
Hello list,
I'm following the paper (http://www.jstatsoft.org/v27/i02/paper) on
how to use "plm" to run panel regressions, and am having trouble with
what I believe should be something very basic.
When I run the command (p.9 in the paper):
R>
dynformula(emp~wage+capital,log=list(capital=FALSE,TRUE),lag=list(emp=2,c(2,3)),diff=list(FALSE,capital=TRUE))
I see:

Optimizing
Hello,
I am fairly new with R and am having trouble finding an optimal group. I
checked the help functions for the various optimize commands and it was a
little over my head.
I have a dataset with 4 columns, name, type, value, and cost. The set
consists of a list of people, which have 3 types. I want to choose 6
people, two of each type, and maximize the sum of their values. However,

Setting log(0) to 0
Hi,
I'm trying to do a regression like this:
wage.r = lm( log(WAGE) ~ log(EXPER)
where EXPER is an integer that goes from 0 to about 50. EXPER contains
some zeros, so you can't take its log, and the above regression
therefore fails. I would like to make R accept log(0) as 0, is that
possible? Or do I have first have to turn the 0's into 1's to be able to
do the above

"Types" of missingness
Dear R-List,
My questions concerns missing values. Specifically, is is possible to
use different "types" of missingness in a dataset and not a
one-size-fits-all NA?
For example, data may be missing because of an outright refusal by a
respondent to answer a question, or because she didn't know an answer,
or because the item simply did not apply. In later analysis it is

instrumental variables regression using ivreg (AER) or tsls (sem)
Dear friends,
I am trying to understand and implement instrumental variables

I found a small (simple) example here which purportedly illustrates the

Simultaneous equation with one ordinal reponses
Dear R users,
I had a research question which involves a simultaneous equation system, one
is the common continuous dependent variable, y1, say wage, or log wage,
another one is a latent variable, y*, which I only observe up to a ordinal
scale, say attitudes toward a problem, taking values as y2= 1, 2, 3 or 4.
Both of them have other exogeneious variables. I have been search on

memory usage grows too fast
Hi All,
I have a 1000x1000000 matrix.
The calculation I would like to do is actually very simple: for each row, calculate the frequency of a given pattern. For example, a toy dataset is as follows.
Col1 Col2 Col3 Col4
01 02 02 00 => Freq of ?02? is 0.5
02 02 02 01 => Freq of ?02? is 0.75
00 02 01 01 ?
My code is quite simple as the following to find the pattern ?02?.

Panel models: Fixed effects & random coefficients in plm
Hello,
I am using {plm} to estimate panel models. I want to estimate a model that
includes fixed effects for time and individual, but has a random individual
effect for the coefficient on the independent variable.
That is, I would like to estimate the model:
Y_it = a_i + a_t + B_i * X_it + e_it
Where i denotes individuals, t denotes time, X is my independent variable,
and B (beta) is the

how to take least risk on rsync dir

When rsync dir_A to dir_B, I hope I wont make any change to the original

there's somethig like

mv dir_B dir_B.bkup &&
mv dir_B_tmp dir_B
This small script can ensure the minimal change time between 2 versions
