问有没有人打算取代SAS。我试过R and matlab。都不行。请问java和python行不行？
有没有相应的工具包？ |

发帖数: 10612 | 5 which language people use to write SAS? It might be c or c++. i took a look
at python, and it seems that there is nothing preventing us from using it to
write analytical programs. same is true for java. we just need some tool-box
ready.
just did a search:
http://jet.codehaus.org/
but it looks very primitive.

发帖数: 2174 | 9 Theoretically, Python can do almost everything C/C++ can do, regardless of
the performance though. So if you want to re-implement from the ground,
Python/Java should be both capable.
But the real questions is: Are most of your work data manipulation or
statistics?
For data manipulation, SAS is probably even worse than R. You probably want
to use Python/Perl, or even C/C++.
For statistics, why kind of task that can be done in SAS, but not in R? R
has some drawback on huge data handling, but there |

发帖数: 194 | 11 You want to take out an industrial standard? You have to ask if all these
companies would like to pay time, money, resources for that.
If you want an industrial job, you'd better be good at SAS.
This is not about what language is better. |

发帖数: 10612 | 13 I am very familiar with SAS. Now I want to learn something to replace it. So
I can easily transfer my skills to everywhere else. Also if I later have a
business myself, I do not want to pay money to SAS.
What I am concerned about is exactly data manipulation part, because I think
R can do stat analysis very well. Are you aware of any data manipulation
package that works well with python (preferred) or java?
Also I am not sure about R's optimization tools. Are you aware of any good

发帖数: 2174 | 15 For data manipulation, you do not really need any packages.
All you need is the general programming philosophy, such as
1) read and write data flow
2) string parsing and object converting
3) flow control, if-else-for-while, etc.
4) communicating with other platform, such as SQL, file system, etc.
Python, Java, C/C++ are all good at these kind of tasks. If you want
heavy-duty data manipulation, you should pick one of those. For light-duty
data manipulation, I feel R is the best, because it is dat
