Two pending features to metricsgraphics

July 5, 2015
By

I’ve been slowly prodding the metricsgraphics package towards a 1.0.0 release, but there are some rough edges that still need sorting out. One of them is the ability to handle passing in variables for the x & y accessor values (you can pass in bare and quoted strings). This can now be achieved (in the

With the creation of the R consortium R has moved up a rung on the ladder of commercial importance. R has captured the early adopters and has picked up a fair few of the early majority (I’m following the technology adoption life-cycle model made popular by the book Crossing the Chasm), i.e., it is starting

The Greek thing II

Just few hours before Greeks head to the polls to decide on the bailout agreement, and ultimately, whether the country will stay in the euro, there is no overwhelming advantage of either side. Actually, the margin became blurred over the last three days, with the "Yes" position rehearsing a last-minute recovery. Despite this last-minute trend, … Read More...

The Greek thing

Greeks have been quite volatile on their opinion whether they should accept or not a proposal by the country's creditors for more austerity to keep aid flowing. The polls conducted over this week look like crazy, though that "belly" was likely provoked by the anxiety on what comes next after Greece not paying IMF back. … Read More...

The state of assertions in R

“Assertion” is computer-science jargon for a run-time check on your code. In R , this typically means function argument checks (“did they pass a numeric vector rather than a character vector into your function?”), and data quality checks (“does the date-of-birth column contain values in the past?”). The four packages R currently has four packages

I was using > library(splines) > fit=lm(y~bs(x,degree=1,df=3),data=df) The problem with that spline function is that knots seem to be fixed. The iterative boosting algorithm is start with...
