R language plays a major role in big data analysis. It is an open source programming language which mainly deals with statistical investigation of data.

R can be self- learnt easily with the help of some online courses or books.

After installing R and R studio, I would suggest to go with some books to kick start. Then read online, take some courses as in udemy and read more and more books. And keep practicing in the R studio. Even if you are without any prior programming experiences, this language is easily understandable and well structured.

Online courses are really worth as it gives you a one to one connection with the instructor while practicing. If you are serious of learning R, don’t be hesitated to take even paid courses.

A bug title is read more frequently than any other part of the bug report. So it has to be meaningful and easily understandable.

For example,

A bug : In the application while the user go to ‘xxx’ tab and search for an item with numeric characters, the app crashes

Poorly written bug title: App crashes

Here the bug title doesn’t summarize the scenario behind the crash

An average bug title: Searching in the ‘xxx’ tab leads to a crash

Here again the bug title is actually creating a false impression of the bug.

It could have better reworded like, “App crashes on searching in the xxx tab with numeric characters”

Infact my suggestion would be to revisit and update the bug title finally, once the report is made fully.

After describing the issue, steps, expected and actual results, just look at the bug title. Definitely, you can do betterment on the same at the final stage.

So initially while starting to file the bug, just add a sentence or even some random keywords in the issue. Or even sometimes, just put whatever comes to your mind, say “my family”. [but of course don’t forget to change it properly at the end].

And finally, once the entire report is ready, revisit the bug title and update it properly. Spend a little more time on the issue title and have two or three revised titles so that it becomes fully meaningful at the end.
