In terms of packages, quantmod has some built-in functions to download directly into R from Yahoo & other providers

 

alternatively if data need limited (&/or one-shot), you might find easier to get them manually &/or through Excel-vba (http://www.diytraders.com they had free spreadsheets for downloading Yahoo/google finance data in the past...not sure if they have it for Mkt Cap)

 

Rgds,

Julien
