I’m trying to use quantmod package in R to get financial data from Yahoo. It works perfectly on my personal laptops (Mac and Win). But I cannot make it work on my working computer (Win7). Here's the error code:
SSL certificate problem: unable to get local issuer certificate
For the sake of debugging this problem, can you reproduce it with the curl tool against a public URL?
What libcurl version and what SSL backend are you using?What's the difference between your personal laptop's Windows installation and your working computer's Windows?
