Hi,
I am not able to work in swirl package in R. I am able to install the
package R. But while giving the library("swirl") command the error comes up.
This is the error message.

It appears that the swirl package expects to have the httr package installed.
You did not include the parameter dependencies=TRUE when you installed swirl.
The default should be fine, guess the httr installation is simply broken.
Best,
