Rcpp::Function("warning") sends empty warnings during development #3

Closed andrechalom closed 8 years ago

I have included a Rcpp::Function warning("warning"); line in the C++ source code in order to send warnings from the C++ code to R, as suggested here. However, this seem to be generating warnings on some operations, such as loading the package with dev_tools and running dev_example:

> load_all()
Loading GillesCom
Warning messages:
1: character(0) 
2: character(0) 
> dev_example("Init_Community")
Loading GillesCom
Running examples in Community.Rd ------------------
> 
> # Initializes the community (in a global object)
> Init_Community(100)
> # Runs 50000 iteractions of the birth-death-migra
> for (i in 1:50000) bdm()
> # Gets and analyzes the abundance vector
> (ab <- as.numeric(abundance()))
(...ETC...)
> f <- sads::fitlnorm(ab[ab>0])
> plot(f, which=1)
> # Simulation internal time elapsed
> time()
[1] 7.348134
Warning message:
character(0)

These warnings are not thrown when the package is loaded with "library(GillesCom)", so this is probably low priority for now.

The warnings were actually being caused by the NAMESPACE listing the imports in the wrong order (see #4), now that I am manually generating the namespace the warnings are gone.
