Hi all,On looking at the source code for the integrate function, I find that it
has the following call:
wk <- .External(C_call_dqagi, ff, rho = environment(),?? ? ? ? ? ?
as.double(bound), inf, as.double(abs.tol), as.double(rel.tol),?? ? ? ? ? ? limit
= limit)How do I access the source code for C_call_dqagi? From other references
("Writing R-extensions section 6.9), I find a reference to Rdqagi when
discussing the integrate function. I would like to know if?C_call_dqagi and
Rdqagi are the same.How do I access the source code for either of these
functions? From the article titled "R help desk Acessing the sources"
by Uwe Ligges in Rnews_2006-4, I gather that the C files can be found in the
folder?$R_HOME/src/main/. But when I look at the equivalent folder in R 3.6.1,?I
find that the main sub-folder is missing in src (the only sub-folder found there
is library). I do not find any C file in the src subfolder?
Where do I find the C source files? How do I get to look at them? I have a lot
of follow-up questions on interfacing with the C files, but I would like to
first know where I can find them. At least on how I can access them.Thanks,Ravi
Sutradhara

Seems like you are looking in the wrong place. Did you download the source code?

Hi Jeff,Thanks for your quick answer. But I don't understand. I have
installed R from the installer (I think that it is called the binary). Do you
mean that I will have to do it via the source? Will I see the source code only
then? Are there any other methods? In any case, it would be helpful if you can
explain what you mean by "downloading the source code".Thanks,Ravi

Also, Uwe's "Accessing the sources": https://cran.r-project.org/doc/Rnews/Rnews_2006-4.pdf, p.43. It's a bit old, but I don't think massively out of date, except possibly with respect to name mangling like thee C_ prefix. -pd> On 5 Aug 2019, at 15:31 , Jeff Newmiller <jdnewmil at dcn.davis.ca.us> wrote: > > Seems like you are looking in the wrong place.
