Do you use RGoogleDocs? If so can you please try run a script now and tell me if you get what I am getting? Error in curlPerform(curl = curl, .opts = opts, .encoding = .encoding) : SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed It came after I ran this: library(RGoogleDocs) ps <-readline(prompt="get the password in ") sheets.con = getGoogleDocsConnection(getGoogleAuth("fxxxh@gmail.com", ps, service ="wise")) ts2=getWorksheets("OnCall",sheets.con) I posted the question on StackOverflow at http://stackoverflow.com/questions/3442781/rgoogledocs-or-rcurl-giving-ssl-certificate-problem Is it a breach of etiquette to cross post?
