similar to: round() and signif() do not check argument names when a single argument is given

I've been inspired to look at the R source code by some strange timing results that I wrote about on my blog at radfordneal.wordpress.com (see the posts on "Speeding up parentheses..." and "Two surprising things...". I discovered that the strange speed advantage of curly brackets over parentheses is partially explained by an inefficiency in the evalList and

I'm trying to generate an R interface for a library that's commonly used and I'm currently writing wrapper functions for file i/o and return an object (list?) that contains the elements of the C structure. For example, reading a file that contains: struct CONFIG_RECORD { char coeffs_filename[256]; char species_filename[256]; unsigned long

Thanks Jan and Tomas for the feedback. Answer from Jan is what I am looking for. Maybe I am not looking in the right place buy it is not easy to understand how these LCONS, CONS, SETCDR...etc works.

Hello R-devel, As mentioned on Fosstodon [1] and discussed during RCOH [2], named arguments to sum(), min(), max() and prod() are currently processed the same way as the un-named ones. Additionally, when specifying the na.rm argument more than once, the last specified value is silently taken into account. Most of this behaviour is exactly as documented, but it's arguably a source of mistakes

Hi, the functions in distn.R were converted from .Internal to .External ([1], in 2012), and to .Call ([2], in 2014). They are still listed as .Internal in names.c, although they are not used in that way. Shouldn?t they be removed? There?s quite some simplification to be had, e.g., do_math3 could go away and do_math2 would be simpler. If that makes sense (I may be missing something?), I?d be

Hi, In line 5, you are allocating a vector of length nc. Then, in line 12, you are using nr as a limit, so if nr goes beyond nc, which is happening in line 39, you are in trouble.

The cmd 'net ads join -U username' dies with 'Segmentation fault' for our PROD ADS environment, however works fine in our DEV ADS environment! The only [Linux] configuration change between the two environments is update SAMBA and Kerberos config to read 'ADS' vs 'ADSDEV' and change the domain controller FQDN. The /var/kerberos/krb5kdc directory, samba/secrets.tdb

GENERAL REFERENCE ON NONLINEAR OPTIMIZATION? What are your favorite references on nonlinear optimization? I like Bates and Watts (1988) Nonlinear Regression Analysis and Its Applications (Wiley), especially for its key insights regarding parameter effects vs. intrinsic curvature. Before I spent time and money on several of the refences cited on the help pages for "optim",

This is a great example how you cannot figure it out after spending two hours troubleshooting, but a few minutes after you post to R-devel, it's just jumps to you (is there a word for this other than "impatient"?); Let me answer my own question. The discrepancy between my sum2() code and the internal code for base::sum() is that the latter uses LDOUBLE = long double (on some system

Is it expected that attributes set on a LGLSXP created by ScalarLogical will apply to all future objects created by ScalarLogical as well? For example: the 'test1' function below returns FALSE and 'test2' returns FALSE with an attribute: library(inline) test1 <- cfunction(body = 'return ScalarLogical(0);') test2 <- cfunction(body = ' SEXP success =

Hi, In Rcpp, we now have a "Function" class to encapsulate functions (they cover all three kinds, but this may change). To call the function, what we do is generate a call with the function as the first node and then evaluate the call. SEXP stats = PROTECT( R_FindNamespace( mkString( "stats") ) ); SEXP rnorm = PROTECT( findVarInFrame( stats, install( "rnorm") ) )
