[Rd] License status of CRAN packages

[Gabor Grothendieck]

Of the 31 packages listed:
 [1] "BARD"          "BayesDA"       "CoCo"          "ConvCalendar"
 [5] "FAiR"          "PTAk"          "RScaLAPACK"    "Rcsdp"
 [9] "SDDA"          "SGP"           "alphahull"     "ash"
[13] "asypow"        "caMassClass"   "gpclib"        "mapproj"
[17] "matlab"        "mclust"        "mclust02"      "mlbench"
[21] "optmatch"      "rankreg"       "realized"      "rngwell19937"
[25] "rtiff"         "rwt"           "scagnostics"   "sgeostat"
[29] "spatialkernel" "tlnise"        "xgobi"

the license fields are AGPL or GPL for 3 and specified in a separate
file "file LICENSE" so about 30 of 1700 < 2% are question marks.
To me that is not inconsistent with all or nearly all being free software
licenses but at any rate this quantifies it a bit better.  (A couple are
not listed below as I got a read error when trying to access its summary
from the CRAN site.  Its possible those 2 are not actually on CRAN.)
