Thanks for the suggestion! That's what we are doing in R_Overlay, |
| 58 |
|
| 59 |
https://wiki.gentoo.org/wiki/Project:Science/Overlay |
| 60 |
|
| 61 |
It is available via layman. It has an eclass very similar to your |
| 62 |
proposal. |
| 63 |
|
| 64 |
https://github.com/gentoo-mirror/R_Overlay/blob/master/eclass/R-packages.eclass |
| 65 |
|
| 66 |
The R_Overlay is automatically generated from CRAN and BIOC. |

Cheers, |
