I think your worry is not necessary! There is a huge community of R users and there are lots of books/articles using R. And I know there are also many companies using R too! So it won't be useless, as long as you are in data zone. Hope this helps!

SSCI和中文C刊认可R的结果吗？

I'm not sure about 中文C刊, but for English journals, it's very common to use R for data analysis. Actually there is a very high impact journal <<Journal of statistical software>> latest Impact factor: >4, and a large portion its articles are about R.

The following is just a list of articles that are published there!

又看了写关于这方面的争论，等手头上的工作弄完了，开始学习R。希望对以后的研究有帮助。

请问能推荐几本R的教材吗？
