reusing external functions across libs
Hi,
I am searching for a way to solve the following problem:
I want to use an external function, defined in a dyn.load()ed shared
object, in another dyn.load()ed shared object.
Currently I have to take the sources (Fortran) from one libraries src/
directory and copy them into the src/ dir of the other library, resulting
in two copies of this function. This is bad for maintanance and maybe

ALTREP: Bug reports
Hello Luke and Gabriel,
Thank you very much for your quick responses. The explanation of STDVEC is
very helpful and I appreciate it! For the wrapper, I have a few new
questions.
1. Like Luke said a mutable object is not possible. However, I noticed that
there is one extra argument *deep* in the function duplicate. I've googled
all the available documentation for ALTREP but I did not find

ALTREP: Bug reports
Hello,
I have encountered two bugs when using ALTREP APIs.
1. STDVEC_DATAPTR
>From RInternal.h file it has a comment:
/* ALTREP support */
> void *(STDVEC_DATAPTR)(SEXP x);
However, this comment might not be true, the easiest way to verify it is to
define a C++ function:
void C_testFunc(SEXP a)

> STDVEC_DATAPTR(a);

and call it in R via

Use R for data aggregation
I have a set of evaluation variables (n) for each sample (sample size is
large enough) and I am trying to use R (nnet package) to aggregate the data.
However, I don't know the weight for each variable (I am sure the weight
shouldn't be equally assigned). Specifically, I have 12 indices (CO2, SO2,
TSP...) for 100 cities and I want to calculate weight for each and finally

How to estimate a hazard ratio using an external hazard function
Hi,
I would like to compare the hazard functions of two samples using the
Cox proportional hazards model. For sample 1 I have individual time-to-
event data. For sample 2 I don't have individual data, but grouped
data that allows to obtain a hazard function.
I am wondering if there is an R function that allows to obtain a
hazard ratio of the two hazard funtions (under the

Hi Jiefei,
Thanks for tryingout the ALTREP stuff and letting us know how it is going.
That said I don't think either of these are bugs, per se, but rather a
misunderstanding of the API. Details inline.

Help on multi-line plot
Hello R-Users
I am struggling with this line plot, it might be simple but I am missing
something here.
First of all I want to make multiple line plots across seasons
(DJF,MAM,JJA,SON) for 12 variables (here, called nodes) and fill them with
the node.
So that season=x-axis, node=line col and freq=y-axis.
My plot currently links all DJFs, MAMs, JJAs and SONs, however I will like
them to be
