Hi,
to embed an iframe into a wiki page the above extension uses
{{Special:IframePage|wiwi|path="examples?R=data/bivariate/chi2_coefficients/example_chi2coeff.R"}}
I wrote a similar extension which is called by
<iframe k="wiwi" p="examples?R=data/bivariate/chi2_coefficients/example_chi2coeff.R" />
I would like to know what would be the advantage of using {{Special:...}} rather than <iframe ... />.
Thanks Sigbert
