Bioinformatics Zen - Data analysis using R functions as objects
http://www.bioinformaticszen.com/post/data-analysis-using-r-functions-as-objects
Data analysis using R functions as objects. Published Fri October 2 2009. The R language is useful because of the available statistical and plotting functions in the base and addon packages. Before using any function though it's usually necessary to get your input data into the format that the function expects. Performing complicated data manipulations with R's standard methods for accessing and subsetting data can however quickly lead to complex and confusing R scripts. I have a function called. With(su...

Shifting sands: March 2015
http://petewerner.blogspot.com/2015_03_01_archive.html
A man with a hammer. Tuesday, March 24, 2015. Simulation and relative performance. There’s been some nice posts on randomness the last week or so, in particular here. I would like to look at how we can use simulations to get a better understanding of how some aspect of a trading system holds up relative to a bunch of random trades. In this example, I look at entries on weekly data for SPY. The entry signal is to buy if the previous week closed down. It looks like this. We can see there’s not a lot ...

Берем из пакета данные по землетрясениям и делаем гистограмму. Берем из пакета данные по землетрясениям и делаем гистограмму. 19-okt.-2013 11:19 pm. Как можно сделать менее убогие гистограммы. Пакет datasets предоставляет много разных данных для анализа. Напоминаю, пакет нужно один раз инсталлировать (выбрав зеркало, когда предложат) и перед каждым использованием заново импортировать (если после последней загрузки закрывали R):. В частности, в пакете datasets есть объект. Данные можно посмотреть, набрав.

Opiate for the masses Data is our religion. Our R package roundup. December 30, 2015. Today is a good day. A year in review. T’s the time of the year again where one eats too much, and gets in a reflective mood! 2015 is nearly over, and us bloggers here at opiateforthemass.es thought it would be nice to argue endlessly which R package was the best/neatest/most fun/most useful/most whatever in this year! But do not despair, dear reader! Top Popular CRAN packages. And parse the CRAN downloads per day using.

Jeromy Anglim's Blog: Psychology and Statistics. Monday, June 4, 2012. How to Convert Sweave LaTeX to knitr R Markdown: Winter Olympic Medals Example. The following analyses of Winter Olympic Medals data have gone through several iterations:. I originally performed similar analyses in February 2010. It was a simple set of commands where you could see the console output and view the plots. With Sweave, I was able to create a document that weaved text, commands, console input, console output, and figures.

Tales at the margin of R, snippets of quant finance and trading, backtesting and possibly martingales. Sunday, 15 April 2012. Ggplot2 Time Series Heatmaps. How do you easily get beautiful calendar heatmaps of time series in ggplot2? I was impressed by the lattice-based implementation from Paul Bleicher of Humedica, which you can find referenced in http:/ blog.revolutionanalytics.com/2009/11/charting-time-series-as-calendar-heat-maps-in-r.html. How do you attack the problem? 16 April 2012 at 04:32. Im fai...
