Perhaps yes. Sorry I did not check the bug reports. Can someone
elaborate on the "undesirable artefacts"? I made two heatmaps using
png() and CairoPNG(), respectively. I can see the difference, but it
is not very clear to me what the artefacts are, or what the facts
should be.

Rcpp is great, and I second that suggestion. But you could also explore
another route and use something like OpenCPU.
OpenCPU is a framework for embedding R in systems and applications. It
exposes a simple HTTP(s) RPC API to call R functions and scripts, and makes
it easy to retrieve the resultin
Hi
Is this the same as "Bug 15462" ?

Hi,
It seems that anti-aliasing in png(type = 'cairo') is not well
supported for the point symbols without boarders, e.g. pch = 16. The
Cairo package works well, though. You can compare png() with

Sorry, I meant I think it is R_MissingArg, not R_UnboundValue. Again though
this is just a guess (though somewhat easily tested).

Jeroen,
The problem seems to be that you are grabbing a symbol that doesn't have a
name. I suspect its R_UnboundValue, but I don't have time to check right
now. Anyway, take a look at this:
> .Internal(inspect(as.list(lm)$data))
@1cada98 01 SYMSXP g1c0 [MARK,NAM(2)] "" (has value)
And compare it

Hi all,

Hi,
We are a company developing a software mainly in C++.
We want to integrate R inside our software in order to use mainly the
engine (usual stats as mean, sigma, Pearson, outlier detection, CPA,
multivariate, ...) and probably later the chart solution.
Of course we don't want to temporary
