Dear Rexperts, I am using R to query google. I am getting different results (in size) for manual queries and queries sent through "getForm" of RCurl. It seems that RCurl limits the size of the text retrieved (the maximum I could get is around 32 k bits). Any idea how to get around this ? Thanks i...

Dear Rexperts, First of all let me say that R is a wonderful and useful piece of software. The only thing is that sometimes it takes me a long time to find out how something can be done, especially when aiming to write compact (and efficient) code. For instance, I have the following function (very rudimen...
