Based on my previous post on Web Scraping I coded and uploaded the Function “GScholarScraper” HERE for testing!
The function will pull all (!) results, processing pages in chunks of 100 results/titles, and return a file with all titles, links, etc. It will also produce a word cloud using the words in the publication titles.

Please try your own search strings and report errors, etc.!

You can source the function by running the following lines:

              destfile = "google_docs_script.txt", mode = "wb")
# read it and run an example:
source(paste(tempdir(), "/google_docs_script.txt", sep = ""))

ls() # the function should be listed

# remove files from tempdir:

Build and run properly under:
R version 2.13.0 (2011-04-13) and R version R-2.13.2 (2011-09-30)
