Tweeting at #IMGC14 conference

The 28th annual International Mammalian Genome Conference was held over the last week in Bar Harbor, MA. For the first time, the official conference hashtag #IMGC14 was introduced. Twitter shares plummeted 9% next day. Pure coincide? I do not think so!

Totally, 79 participants contributed 1546 tweets. Guess who was the Twitter evangelist?

The distribution of tweets in time reveals when the lobster was served as a conference dinner.

RStudio: Pushing to Github with ssh-authentication

If RStudio prompts you for a username and password every time you try to push your project to Github, open the shell (Git menu: More/Shel...) and do the following:

1) Set username and email (if you did not do that before)
git config --global "your_username"
git config --global ""

2) Create SSH key
ssh-keygen -t rsa -C "" 

In RStudio, go to menu Tools / Global options / Git SVN / View public key and copy the key to your Github account setting (Edit profile / SSH keys / Add SSH key).

To check that ssh-authentication works, try to run
ssh -T

and you should get something like

Hi your_username! You've successfully authenticated, but GitHub does not provide shell access. 

3) Change remote.origin.url from HTTPS to HTTP 

It might be Windows specific, but after 1)+2) RStudio still asks me for user name and password. After a long Google search, I have found a solution here and that is
git config remote.origin.url

Hip, Hip, Hurrah!

If it was trivial for you, I do apologize. I am still very bad in guessing what could be useful for somebody and what not so much. That is why I have this blog and Github account in the first place.

One example, last year I published a paper in JSPI journal that improves a test for interaction in some very specific 2-way ANOVA situation (just one observation per group). The paper submission was an odyssey, mostly because of me. In one moment I doubted whether to retract the paper or not and I even did not upload the package to CRAN at first, just put it on Github.

Then I discovered that some guys found it and had built their package using it. They presented the results at UseR! 2013 conference. I might have met one of those biologists but I am sure I never mentioned my package to them. Finally, - and this is a bit embarrassing - I received an email from Fernando Tusell that I misspelled his name in one of my functions.

In summary, even if you see your work as non-essential from your perceptive, the others may have different view. Just do your best and share your results. Github is a perfect place for this.

Shiny Year 2014 (source on Github)

"Pour Felicitér" is a French phrase used by Czech and Slovak to wish a happy new year, but not in French speaking countries. It is dating back to the beginning of 19. century when French was popular in Czech/Austrian city population similar way as English is today.

I originally wanted to make it a snow flake to share a plenty of snow we have in Maine. But then I discovered this Xmas R post and made it Shiny.

Let your 2014 be shiny as well!
