[Rcpp-devel] -Wconversion

[Kirill Müller]

For RSQLite, I wanted to double-check that I'm not inadvertently 
truncating integer values. Unfortunately, enabling -Wconversion gives me 
several false positives that originate from Rcpp headers.

I was able to fix these locally by editing 11 header files (see list 
below), mostly by replacing int with size_t or R_xlen_t, or by adding 
casts. Happy to submit several pull requests, but wanted to discuss 
scope and granularity first:

- one PR each for Dimension.h, api/, date_datetime/, module/, sugar/, 
vector/
- one PR per affected file
- one PR per affected line of code?
