R help - Jan 2018 - How to programmatically save a web-page using R (mimicking Command+S)

Hi,

I would appreciate if someone can give me a pointer on how to save a
webpage programmatically using R.

For example, let say I have this webpage open in my browser:

http://www.bseindia.com/stock-share-price/dabur-india-ltd/dabur/500096/

When manually I save this page, I just press Command+S (using Mac) and
then this page get saved in hard-disk

Now I want R to mimic this same job that I do using Command-S

So far I have tried with readLines() however the output content is
different than what I could achieve using Command+S

Any help will be highly appreciated.

Thanks for your time.

The 'webshot' package (on CRAN) can do this.

Henrik

Hi Henrik,

Thanks for your pointer. Saving via PDF is working for me, however, in
many cases, it is unusually taking a long time.

In many cases I am facing Error too as below. This is particularly
occurring if I trigger Multicore calculation option

webshot.js returned failure value: 1

Just wondering if there is any other direct ways to achieve the same.

Thanks,

The command-line utility 'wget' can download websites,
including graphics, etc. Look for 'mirror' in its
documentation if you want to download the complete
site. It is usually available by default on Unix-style
systems; I am sure there is a version for Mac. If you
insist on using R, you could write a simple wrapper,
using ?system or ?system2.
