"Problem: internal error"

Colleagues,

I encountered an unexpected error in S-Plus:
	Problem: internal error: trying to fee an overwritten block of S  
storage, probably in frame 14

Windows Vista, S-Plus 8.1.1

The error occurred when a lengthy script was creating graphics.  There  
were no other error messages (other than "use traceback").  Does  
anyone have a clue what this means?

Demers Regression

Hi,

Is it possible to run a Demers Regression in S-Plus, and if so, how is this done?

I'm using S-Plus 8.0, and running it in Windows XP.

Thanks very much,

Liz

I’ve gotten a couple of emails asking about the stem and leaf plot for hours.  This actually is best done in large buckets, like 50’s; but that is a bit cumbersome.  So rather than hours let’s use days as in the following table

CFP: AHSWN - An International Journal, Special Issue on User-oriented, Service-oriented and Spontaneous Wireless Ad-hoc Networks


[Apologize in advance for cross-postings]

-----------------------------------------------------------------------------------------------------------------------

Call for Papers

Ad Hoc & Sensor Wireless Networks: An International Journal
Special Issue on
User-oriented, Service-oriented and Spontaneous Wireless Ad-hoc Networks

http://www.oldcitypublishing.com/AHSWN/AHSWN.html

Overview

There are many Ad Hoc Wireless Networks where several types of users and services must be integrated. In a
user-oriented network, the service quality and the corresponding service for each user must be
guaranteed. On the other hand, the user behaviour and the services offered for the users could affect to
the wireless ad hoc network performance. A spontaneous ad hoc network enables a group of users to work
together collaboratively coming together at the same time, and very close to each other, to be able to
communicate. They seek to imitate human relationships in order to work together in groups, running on an
existing technology. The devices used for this type of networks have limited resources, few computing
capacity and low energy consumption. They can be used for the integration of ser
 vices and users in order to solve a problem or to carry out a specific task, or for sharing services and
resources, with no dependence on a central server. The range of environments in whic!
 h these networks can be applied is 
wide and may include many user collaboration ad hoc wireless systems.

Authors are invited to submit complete unpublished papers, which are not under review in any other
journal. The topics suggested can be discussed in term of concepts, state of the art, standards, designs,
implementations, running experiments or applications. 

Topics of interest include, but are not limited to:

-	Network protocols and architectures
-	Self-organization and self-configuration algorithms
-	Nodes cooperation and distributed coordination
-	Security, privacy, data integrity, authentication and trust
-	Energy models, design and management
-	Integration with other systems
-	Location and mobility management 
-	Resource provisioning, dynamic resource management and quality of service
-	Fault tolerance and reliability 
-	Modelling and simulation techniques 
-	Design and deployment of embedded system platforms
-	Software platforms and development tools 
-	Practical implementations, developments and real-world experiences 

Important dates:

Paper submission: June 1, 2010
Acceptance notification: September 15, 2010
Final Papers:  October 15, 2010
Tentative Publication: 1st quarter 2011

Submission Guidelines:

The submitted papers must be written in English and describe original research work which is not published
nor currently under review by other journals or conferences.  Papers previously published in
conference/workshop proceedings can be considered, but should be substantially extended. An
electronic copy of the complete manuscript and any supplementary material should be sent by e-mail to the
corresponding editor (jlloret <at> dcom.upv.es). Each submission must be clearly identified as a
submission for this special issue by writing the Special Issue title in the subject. The submission must
include the title, abstract of your paper, and the corresponding author's name and affiliation. All the
submissions will be subject to peer review in accordance with the journal review procedures. They wil
 l be rigorously reviewed based on the quality: originality, high scientific quality, organization and
clarity of writing, and support provided for assertions and conclusion.

Submission Format:

All submissions should be made as Microsoft Word or pdf documents. All manuscripts must be submitted in
English. Manuscripts submitted as Microsoft Word documents should be double-spaced, presented in an
easily readable, standard font and size (such as 10 or 12 pt. Times or Arial). All pages should be numbered.
Manuscripts submitted as pdf documents are encouraged to follow the layout guidelines provided by the
publisher (http://www.oldcitypublishing.com/Layout%20Guidelines.pdf). More information about
the paper format is provided in:
http://www.oldcitypublishing.com/AHSWN/AHSWN%20Contributor%20notes.html
