package with Stan functions failed to compile

[wds15]

Hi!

I have a package called RBesT which I keep in a git repo called BesT... this is why the directory I am using to develop is called BesT rather than RBesT. As a result the code here:

rstantools/R/rstan_config.R

Line 221 in 99c0d66

paste(basename(pkgdir), "types.h", sep = "_")),

creates a src/BesT_types.hpp file. This file is then ignored by Rcpp which then fails to include the file into src/RcppExports.cpp. Rather than using the package directory as a way to determine the R package name, the much better way is to do as Rcpp does here:

https://github.com/RcppCore/Rcpp/blob/6193de530785f1d84117a852cf7e478b1f048b2f/R/Attributes.R#L422

this use the package DESCRIPTION file to tweak out the R package name.

Something like this is also enough:

strsplit(x = readLines("DESCRIPTION", n = 1, warn = FALSE),
         split = "Package: ", fixed = TRUE)[[1]][2]

Thanks for pointing this out. Do either of you have time to put together a quick PR? I'm a bit overloaded at the moment.
