支持开源软件

两个都开源好像

看你要干啥，只是做文章的话，R吧，通用一点，计量的包也多一点
你要是做项目，要对接服务器啊，前段后台什么的，那就还是用Python
R的缺陷：内存容易崩，与其他语言对接比较悲剧
Python的缺陷：并行缺陷，处理千万到亿级别数据时就慢

I prefer R for econometrics. Just my personal preference. Python is more for general purpose, like web scrapping, gaming, text mining. But more and more people are using Python for deep learning. But R has a very steep learning curve. On the other hand, Python is easier to learn. For econometrics, there are lots of R packages available for analytics. For Python, I am not quite sure since I did not use its econometrics package. Welcome on board for R!

Thanks for your wonderful commemts!
