This is, I think, the main reason R has lost a lot of market share to Pandas. As far as I know, there's no way to write even a rudimentary web interface (for example) in R, and if there is, I think the language doesn't suit the task very well. Pandas might be less ergonomic for statistical tasks, but when you want to do anything with the statistical results, you've got the entire Python ecosystem at your fingertips. I'd love to see some way of embedding R in Python (or some other language).
