lsoda
I am running R 1.2.3 with ESS5.1.18 with Windows 98.
I am trying to use lsoda in the odesolve apckage and am having problems.
Question:
The return value of the function of the system of ode's has to be a list
that includes first, the ode's and second, "a vector
(possibly with a `names' attribute) of global values that are
required at each point in `times'."

nlme and "Mixed- Effects Models..." in Windows
(windows 98, R 1.2.3, ESS 5.1.18, nlme 3.1 from CRAN)
Dear R users,
I am trying to follow Pinheiro and Bates book ("Mixed-Effects Models in S
and S-PLUS"). I downloaded the nlme package from CRAN, and unzipped all the
data and help files. Unfortunately, I cannot generate the figures in the
book. For instance, their appears to be no plot.design or intervals plotting
functions.

deriv value
How do I get eval( deriv(~F,"x") ) to return ONLY the values of the
derivative of F?
the default returns values of F(x), AND F'(x) as a ".gradient" attribute,
and , after reading everything I have on eval(), deriv(), and attr(), I had
absolutely no idea how to get just F'(x) evaluated a x.
Many thanks,
Henry

simple question
How does one turn a character string back into an object?
I would like to take character strings and use them as objects, a process
that I think is the reverse of deparse( substitute(X)).
E.g., I would like to get the variable names from the fourth object listed
with objects(),
something like
names(objects()[4]), but of course that doesn't work.
Thanks

format for tick labels
Running R 1.2.3, Windows 98
I checked the archives, and I couldn't find anything pertaining to this:
How do I control format (scientific notation versus decimal, e.g.) on tick
labels?
TIA,

Interacting with R
Dear R folks,
(Running Windows 98, Pentium II, 128 Mb RAM)
I have been using Splus 2000 for about 1.5 years, and have recently begun using R. I love the Open Source philosophy! I may be switching to to Linux soon.
My question:
How do people most often interact with R?
In Splus 2000, I used "Script" windows to write functions. "Script" windows were great because:

unlinking
Quick question. How important are these? Are the errors recoverable and
not a big deal, or are they actually a problem? I see a few of these
randomly over the course of the day.

[LLVMdev] Segmentation fault 'cause of accessing function arguments
Hi all,
I am experimenting to run a pass inherited from CallGraphSCCPass. In
the pass, I iterate all functions in a SCC. In each iteration, I
access all arguments of a function in the following way:
Function::arg_iterator PI = fun->arg_begin(), PE = fun->arg_end();
...
I have no trouble with building. However, I am troubled with
"segmentation fault" when I run the pass

[LLVMdev] What is the right way to register an alias analysis pass
Hi everyone,
I am wondering what is the right way to register an alias analysis
pass.
My alias analysis pass is implemented in a dynamic load module. As I
can see, a general way to register a pass looks like:
llvm::RegisterPass<Analyzer> X("rci", "RCI Pass");
However, registering a type-based analysis uses:
INITIALIZE_AG_PASS(...)

Compact letter display for interaction effects
Hello,
I am interested in generating a compact letter display for the results
of Tukey HSD tests that contain interaction effects. The 'cld' method in
the 'multcomp' package seems only to work for main effects. Does such a
thing exist already? Thank you for any thoughts,
Josh

[BioC] RCurl loading problem with 64 bit linux distribution
Martin,
Well, thanks for jumping in! We need all the help we can get ;)
I changed the execute bit as you suggested and recompiled, no luck, still
the same error message.
Below is the output you wanted me to look at, its a bit beyond me so I
include both a brief grep summary and then the whole enchilada. I do note
that my output is different from yours, but I'm not sure how to interpret.

Help in Compliling user -defined functions in Rpart
I have been trying to write my own user defined function in Rpart.I
imitated the anova splitting rule which is given as an example.In the

is in between -1 and +1.So my deviance is given by
abs(ci)*(1-abs(ci)).Now when I run rpart incorporating this user

But now I find that yum reports nothing available:

No package R-devel available.
No package R available.
So I went to check manually in the download directory, e.g.

[LLVMdev] Possible bug in the ARM backend?
Hi,
I'm working on the iterated register coalescing graph coloring
allocator and try to test it with all backends available currently in
LLVM.
Initial tests with most of the backends are successful.
It turned out that my allocator triggers a specific assertion in the
RegScavenger and only for the ARM target. It looks like the LR
register is used for frame pointer related things,

saving plots
Hi all, I am have an R script that makes many plots, and I would like to
string them into a movie file. To do that I have to save all of my plots as
jpegs or gifs. I don't want to go through all of my plots and save them by
hand though. Is there a way to automate saving the plots as a gif or a jpeg
so I can string them into a movie?
Thanks in advance

changing default arguments of a function and return the modified function as a result
Dear R-users,
I am trying to develop a function that takes another function as an argument,
changes its default values and returns a list of things, among which the
initial function with its default arguments changed. An example of what i
will like to obtain below:
## initial function
myfun <- function(x, a=19, b=21){ return(a * x + b) }
## this is the function i will like to create
