Obamacare website Utter Failure

Obamacare website has been a total disappointment from start. When healthcare.gov was opened to public on October 1, 2013 it crashed and the government blamed the overwhelming visitors of the site. It's now fixed, but there are new unresolved problems particularly in name registration, eligibility questions and in the most important step of buying insurance. It led users to cryptic error messages or enduring long waits when trying to sign up.

The number of Obamacare website problems since the website opened has been deeply embarrassing for the White House. The drawbacks have called into question whether the Obama administration is capable of implementing the complex policy they seems to be unaware of the scope of the problems when the exchange sites opened.

Even Obama acknowledges problems:

�Nobody is madder than me about the fact that the website is not working as well as it should, which means it�s gonna get fixed,� Obama said.

He even turn to an ex-adviser Jeffrey Zients, he is the former acting director of the White House budget office.

A person close to the project said that "No way it was properly tested before it went live" since the website is full of bugs and junk computer codes.

Review: K�lner R Meeting 18 October 2013

The Cologne R user group met last Friday for two talks on split apply combine in R and XLConnect by Bernd Wei� and G�nter Faes respectively, before the usual Schnitzel and K�lsch at the Lux.

Split apply combine in R

The apply family of functions in R is incredible powerful, yet for newcomers often somewhat mysterious. Thus, Bernd gave an overview of the different apply functions and their cousins. The various functions differ in their object inputs, e.g. vectors, arrays, data frames or lists, and their outputs. Other related functions are by, aggregate and ave. While functions like aggregate reduce the output size, others like ave will return as many rows as the input object and repeat the results where necessary.

Alternatively to the base R function Bernd touched also on the **ply functions of the plyr package. The function names are certainly easier to remember, but their syntax can be a little awkward (.()). Bernd's slides, in German, are already available from our Meetup site.

XLConnect

When dealing with data stored in spreadsheets most member of the group rely on read.csv and write.csv in R. However, if you have a spreadsheet with multiple tabs and formatted numbers, read.csv becomes clumsy, as you would have to save each tab without any formatting in separate files.

G�nter presented the XLConnect as an alternative to read.csv or indeed RODBC for reading spreadsheet data. It uses the Apache POI API as the underlying interface. XLConnect requires a Java runtime environment on your computer, but no installation of Excel. That makes it a true platform independent solution to exchange data with spreadsheets and R. Not only can you read defined rows and columns from Excel into R, or indeed named ranges, but in the same way data can be stored in Excel files again and to top it all - also graphic output from R.

Next K�lner R meeting

The next meeting is scheduled for 13 December 2013. A discussion of the data.table package is already on the agenda.

Please get in touch if you would like to present and share your experience, or indeed if you have a request for a topic you would like to hear more about. For more details see also our Meetup page.

Thanks again to Bernd Wei� for hosting the event and Revolution Analytics for their sponsorship.
