Hi
I would like to know how I can access the individual fields contained in an R object. Or, more precisely, how to get R to tell me how.
For example, if I run the following code:
dx.ct <- ur.df(dat1[,'dx'], lags=3, type='trend')
summary(dx.ct)
then I get this output:

I've been adding quite a bit of javascript to my pages lately, but have learned it all in classic seat-of-the-pants fashion. When I want my page to do something, I google and experiment until I get the result I want.
I frequently have objects in my pages that I want to activate/deactivate, hide, show, etc., but - having missed the ri...
Is it possible to concatenate variable names in C? Specifically, I have a struct that contains 6 similar variables in it called class1, class2, class3, etc.
I want to run through a for loop to assign each variable a value, but I can't see how to do it without somehow concatenating the variable name with the value of the for loop counter...
I need to assign names to the values of a Jquery UI slider is this possible?
Here's the code so far:
<script type="text/javascript">
$(function() {
$("#slider_style").slider({
value:2,
min: 1,
max: 3,
step: 1,
slide: function(event, ui) {

When taken literally, it makes sense, but what exactly does it mean to be a significant character of a variable name?
I'm a beginning learner of C using K&R. Here's a direct quote from the book:
"At least the first 31 characters of an internal name are significant. For function names and external variables, the number may be less than ...
I have a dilemma that I've encountered before. What's the best in terms of usability when one displays personal names in a table? Should there be a single column for the name? If so, is "firstname lastname" or "lastname, firstname" preferable? Or would a column for "firstname" and a column for "lastname" be best? I'm thinking in terms of...
In my Java project I need to list all class names in the current package, I usually run my app in two different modes : <1> From NetBeans, <2> From an executable jar file packaged by the NetBeans.
My question is : How to write my program so that no matter which mode it is running, it can list all the class names in my app. Because when ...
I compiled my library (specifically protbuf-2.3.0) using -g -O0 on a SunOS 5.10.
A sample line in the make log is this:

I have a couple of functions inside a class that essentially do the same thing:
public function fn_a(){
return __FUNCTION__;
}
public function fn_b(){
return __FUNCTION__;
}
public function fn_c(){
return __FUNCTION__;
}
I need those functions to remain in their current names so I intentionally did not do:

I am writing a Winform UI in which the user must select a single customer. (For reasons beyond my control I am limited to a UI that uses dropdown lists, text fields, checkboxes, radiobuttons only -i.e. no fancy special UI controls)
The situation
There are a lot of customers (a thousand for example)
If i put all the customers in a sing...
Now following my series of "python newbie questions" and based on another question.

Go to http://python.net/~goodger/projects/pycon/2007/idiomatic/handout.html#other-languages-have-variables and scroll down to "Default Parameter Values". There you can find the following:

Hi, first time poster, long time reader so be gentle with me :)
See the following code which works to generate me timestamps for the beginning and end of every month in a financial year.
int year = 2010;
// Financial year runs from Sept-Aug so earlyMonths are those where year = FY-1 and lateMonths are those where year = FY
int[] earlyM...
I am using VSTO to create an Excel add-in.
My plan is to persist objects inside of excel workbooks by serializing them to strings and assigning those strings to be the values of names in the workbook.
However, when I call the API function to add the new name, I get a mysterious exception from the COM library.
More precisely, I am call...
In R, "assign('x',v)" sets the object whose name is 'x' to v. Replace 'x' by the result of applying a text function to a variable x. Then "assign" shows its worth.
Unfortunately, "assign(paste('names(','x',')',sep=''),v)" fails. So if 'x' is a variable x, I can set its value, but I can't give it names for its elements.
Can one work ...
i got a code of 100-200 rules for making a table. but the whole time is happening the same.
i got a variable $xm3, then i make a column . next row, i got $xm2 and make column. next row, i got $xm1 and make column.
so my variables are going to $xm3, $xm2, $xm1, $xm0, $xp1, $xp2, $xp3.
is there a way to make a forloop so i can fill $xm a...
Here is a tricky situation, and i wonder what ways there are to solve it
namespace {
template <class T>
struct Template { /* ... */ };
}
typedef Template<int> Template;
Sadly, the Template typedef interferes with the Template template in the unnamed namespace. When you try to do Template<float> in the global scope, the compiler...
The ec2-describe-instances command is not very helpful in distinguishing the instances.
Are there command line tools that give a better overview?
Perhaps somewhat like http://github.com/newbamboo/manec2 but with support for different regions etc.

It's good to have consistency in file names.
MyActivity.java contains the public class MyActivity
I would like the xml file with its layout to be called res/layout/MyActivity.xml
But I get an error message saying "Invalid file name: must contain only [a-z0-9_.]"
So two questions:
Why is the character set so limited (not even upper ...
Hi,
I have the following problem.
My table, say tab1, has name column as follows "LastName, FirstName". I want to make it so that the column becomes "FirstName LastName".
Any ideas on how this is to be done? Note that there is no comma present, but i guess that can be easily removed once I figure out how to actually flip the first and ...
