r - Using the 'available.packages' Function to Retrieve Emails -

-

i attempting retrieve email addresses of contributing package authors , maintainers r-project. function reads follows:

availpkgs <- available.packages(contriburl = contrib.url(getoption("repos"), type),     method, fields = null, type = getoption("pkgtype"),     filters = null)

i've attempted different character values in fields parameter retrieve maintainer , author info 'packages' files, have not been had luck. know how might approach this? thank in advance time.

i not think author information in available.packages() retrieves:

r> ap <- available.packages() r> colnames(ap)  [1] "package"    "version"    "priority"    [4] "bundle"     "contains"   "depends"     [7] "imports"    "linkingto"  "suggests"   [10] "enhances"   "os_type"    "license"    [13] "file"       "repository" r>

so maybe need combine per-package lookup of description info @ cran (or mirror). that, , few more things, in 200-line script driving cranberries rss feed / html summary of package updates @ cran stores stateful info in sqlite. this, retrieve author, maintainer etc directly package looking @ rather in 1 big global scoop. said, there may of course other meta-data @ cran this...
