Is there a function like "is.there" such that is.there ( a ) returns TRUE is object 'a' is in the current environment and FALSE otherwise? Thank you. Francisco J. Molina

I am using 1.7.1 in a PC ( redhat 9, linux ) I created a subroutine in C++, mySubrutine, to be used in R. To debug this subroutine I have a main routine in C++ that calls mySubrutine. The only thing main () does is to provide mySubrutine with its arguments (this is the easiest way for me to debug subroutines written in C++ and intended to be used in R ). I also have a version of the same

My computer is a pentium 4 running at 2.4 GHz. My R is 1.7.1 I have written a program in R that calls C++. The program spends most of the time in C++ ( > 90% ). R basically deals with output and input. How slower can this be compared with the program I would get from rewriting everything in C++? Thank you.

Hi, I have plotted the graph of x^2 and I would like to add to it a line that is currently outside of the plot ( the points of the line fall outside of the plot ). When I use the function 'lines' the graphics window does not became larger to show this line. Is there any way I can fix this? Also, how can I eliminate the axis from the plot? Thank you.

In "Frequently Asked Questions on R" there is a section "Debugging R from within Emacs" I suppose this is for developpers ( not useful to debug R source code ). Am I right?

Acording to the documentation in gsl "The physical row dimension tda, or trailing dimension, specifies the size of a row of the matrix as laid out in memory" I think that if I pass a matrix to C++ through .C as single ( or.double ), that is, .C ( as.single ( matrix )) then the tda is simply the number of elements of that matrix. Am I right? Thank you.

I'm trying this again because the last attempt didn't go through (thus more or less proving one of the below to be true.)

Dear Ana When you installed R it gave you an option to put a shortcut on the desktop. If you did that then you can start the R GUI by clicking on it. You may need to customise it for your preferences. Specifically it starts R with an option cd-user-docs which I delete and I then alter the starting option to start in the directory I want. You may have different preferences of course. Try

Hi everyone, I was just wondering, does anyone managing production asterisk servers migrated successfully from 1.4.2X to 1.6.0.X? I would like to see if there are some successful cases. Is your 1.6.0.X behaving well, with acceptable stability? Please share your experiences. Thanks, -- Ing.

Hi all, I'm testing the persistent dynamic queue members functionality on 1.6.0.10. The queue members are agents defined in the agents.conf file. When I issue an asterisk restart and check the queue members again on the CLI, all of them are listed as /invalid/ and there is no way to change this but to unload app_queue.so and load it again. My guess is that the internal AstDB queue
