Erez, I think the API is very explicit about this, NULL is not an accepted input for any function taking SEXP by design. The special case of try*Eval() return values can be taken as a case where the resulting object is not actually SEXP but rather a special type which can be NULL (=failure) or SEXP. It may be even perhaps useful to declare it as a separate type to make this clearer, but I

Thank you Ivan, At this point, without it being documented explicitly, I tend to lean on the safe side. If the non-null assumption is ever incorrect, on debug and safe builds unwrapping is an assert that will guarantee to crash R. While the source code has plenty of NULL checks, also for some SEXP, it's hard to tell just from grepping if any are related to the public API or not. Secondly

Hello everybody I'm putting finishing touches to a library, and have noticed that the .dvi file that R CMD check creates does not sort the functions in alphabetical order. I find this odd because I used the "tidy" routines in section 3.1 of the R-exts manual, which produce R code in which the functions are alphabetically ordered (and I performed R CMD check using the

That definitely looks like a bug, but not one that anyone will be eager to fix. It's very old code that tried to be clever, and that's the hardest kind of code to fix. Remember Kernighan's Law: "Everyone knows that debugging is twice as hard as writing a program in the first place. So if you?re as clever as you can be when you write it, how will you ever debug it?"

At least I cannot find any mention of plot.first in the R source code. In this example,

Hello, I'm working on bindings for the API (for zig), and was wondering if the R's C API guarantees it won't return null pointers? The only reference I found in the "Writing R Extensions" manual where this not the case is `R_tryEval` and `R_tryEvalSilent`. Otherwise it's unclear. The reason I care about this is syntax. Because I don't know whether SEXPs are NULL or

I have a long equation that I need to break in the R documentation of a package or it trails off the right hand side of the page. Here's the formula: \deqn{Cov(r_{ist}, r_{iuv})= [.5\rho_{ist}\rho_{iuv}(\rho_{isu}^2 + \rho_{isv}^2 + \rho_{itu}^2 + \rho_{itv}^2) + \rho_{isu}\rho_{itv}+ \rho_{isv}\rho_{itu}-(\rho_{ist}\rho_{isu}\rho_{isv} + \rho_{its}\rho_{itu}\rho_{itv}) +

I just installed R-1.7.0 on Darwin 6.6 (a.k.a. MacOS 10.2.6). 'make' and 'make check' run without any problems. 'make info' builds with no complaints, but 'make dvi' and 'make pdf' fail. I get refman.dvi and refman.pdf OK (with some warnings from pdftex that some names are referenced that do not exist), but R-FAQ.{dvi,pdf} fails as shown below. Attempts

Dear list, I've noticed for some packages the Index file in the help system has a single list of objects (arranged alphabetically), while for other packages this list is offered separately by letters... presumably when the number of help objects is high. Is there a way to manually split the help objects into categories? For example, I would like to have an alphabetic order for the group

Hi all, I wanto to run a plot about the levels of a variable parting on an ols regression. The regression in done on the rate of return of the variable. Imagine R_{t}=a+b*R_{t-1} So If P, the "estimated" price would be P_{t}=P_{t-1}*R_{t} Imagine that I obtain lm fitted values and the original R_{t}, R_{t-1} are [1000,1] dimmension... How it is posible to obtain also 1000,1 fitted

Hello, I have been using the TM package to create a TermDocMatrix, which I have saved as a matrix so that I can view word frequencies. Below is a section of the code that I have used and an excerpt of the output: What I wanted to be able to do is to view the output alphabetically - rather than the results being sorted by frequency as below, that an alphabetical list would be generated.

Hello. I am trying to build 64 bit R-3.4.0 (specifically R-patched_2017-04-23) on Windows 64 and have run into an issue with building the html files.

Hi all, I've noticed some peculiarities in the tools:::funAPI output that complicate its programmatic use a bit. - Is it for remapped symbol names (with Rf_ or the Fortran underscore), or for unmapped names (without Rf_ or the underscore)? I see that the functions marked in WRE are almost all (except Rf_installChar and Rf_installTrChar) unmapped. This makes a lot of sense because some

The document R-exts contains the following example of using mathematics in R documentation. \deqn{p(x) = {\lambda^x\ \frac{e^{-\lambda}}{x!}} {p(x) = lambda^x exp(-lambda)/x!} There is a syntax error in there, but that's not my point. The problem is that using "R CMD Rd2dvi" I find that putting the alternate forms of the equation on top of each other doesn't work.
