> sessioninfo()  r version 3.1.1 (2014-07-10) platform: x86_64-w64-mingw32/x64 (64-bit)  locale: [1] lc_collate=english_united states.1252  lc_ctype=english_united states.1252    [3] lc_monetary=english_united states.1252 lc_numeric=c                           [5] lc_time=english_united states.1252      attached base packages: [1] stats     graphics  grdevices utils     datasets  methods   base       other attached packages: [1] reshape2_1.4  ggplot2_1.0.0 xml_3.98-1.1  dplyr_0.2      loaded via namespace (and not attached):  [1] assertthat_0.1   colorspace_1.2-4 digest_0.6.4     grid_3.1.1       gtable_0.1.2      [6] magrittr_1.0.1   mass_7.3-33      munsell_0.4.2    parallel_3.1.1   plyr_1.8.1       [11] proto_0.3-10     rcpp_0.11.2      scales_0.2.4     stringr_0.6.2    tools_3.1.1

require(httr)  doc <- htmltreeparse('http://www.lewisthomason.com/locations/', useinternal = true) doc <- content(get('http://www.lewisthomason.com/locations/'))
