Escalating Life Expectancy

July 18, 2016 | Andrew Collier

I’ve added mortality data to the lifespan package. A result that immediately emerges from these data is that average life expectancy is steadily climbing. The effect is more pronounced for men, rising from around 66.5 in 1994 to 70.0 in 2014. The corresponding values for women are 74.6 and 76.5 respectively. Good news for everyone. […] [Read more...]

Dance of the Bayes factors

July 18, 2016 | Daniel Lakens

You might have seen the ‘Dance of the p-values’ video by Geoff Cumming (if not, watch it here). Because p-values and the default Bayes factors (Rouder, Speckman, Sun, Morey, & Iverson, 2009) are both calculated directly from t-values and sample sizes, we might expect there is also a Dance of the Bayes ...

New Release of partools Package

July 17, 2016 | matloff

My new release of partools is now on CRAN. The package is aimed at doing parallel data science in what I call an “un-MapReduce” manner. It takes the point of view that MapReduce-based frameworks such as Hadoop and Spark are fine for the types of applications their designers had in ... [Read more...]

Data frame columns as arguments to dplyr functions

July 17, 2016 | Econometrics and Free Software

Suppose that you would like to create a function which does a series of computations on a data frame. You would like to pass a column as this function’s argument. Something like: 
data(cars)
convertToKmh <- function(dataset, col_name){
  dataset$col_name <- dataset$speed * 1.609344
  return(dataset)
}
This example is obviously not very interesting (you don’t need a function for this), but ... [Read more...]
