I was running the "R Programming Basic Building Blocks", in the Swirl package. Everything was going well, until this point:
""Anytime you have questions about a particular function, you can access R's
| built-in help files via the ? command. For example, if you want more
| information on the c() function, type ?c without the parentheses that
| normally follow a function name. Give it a try.""
I´d tried many and many times. just appeared the following message:
"" ?c Error in shell.exec(url) : access to 'http://127.0.0.1:31006/library/base/html/c.html' denied""
Even when I pressed "skip () ", it showed the correct answer and the same message:
""?c Error in shell.exec(url) : access to 'http://127.0.0.1:31006/library/base/html/c.html' denied""
| Leaving swirl now. Type swirl() to resume.
Anyone here know how to solve this problem?
TIA
