[R] A competition to create a recommendation engine for R packages

[Kjetil Halvorsen]

Follow-up. Started to look at this. First step is to make a graph
showing dependencies between R packages(CRAN, Bioconductor,Omegahat).
As a curiosum,  this graph has diameter 20:
> require(igraph)
> diameter(CRANgraph)
[1] 20
> dia <- get.diameter(CRANgraph)
> dia
 [1]  221 1866 2344 2192  330 1615  994 2603 2477 1419 1497 2920 2907 3449 2812
[16] 2630 2620 2690 2772 2789 1518
> packFrame[dia+1,1]
 [1] "GGMselect"     "network"       "sna"           "rgl"
 [5] "MASS"          "lattice"       "chron"         "zoo"
 [9] "tis"           "ggplot2"       "hexbin"        "marray"
[13] "limma"         "org.Hs.eg.db"  "annotate"      "Biostrings"
[17] "BSgenome"      "GenomicRanges" "Rsamtools"     "ShortRead"
[21] "hwriter"

Here is used an inclusive definition of link, using all the fields
Depends,Suggests,Imports,LinkingTo, Enhances.
