I have started redoing the source code measurements that appear in my C book, this time using a lot more source, upgraded versions of existing tools, plus some new tools such as Coccinelle and R. The intent is to make the code and data available in a form that is easy for others to use
In this post, I’ll be graphing some results from a recent referendum held here in the UK and combining it with the results of a set of local elections that were held at the same time. I’ll give some examples of graphing stuff using ggplot2 and will also show some info regarding merging datasets. At
Jeffrey Ryan's quantmod package makes it simple to download and graph pricing data from a variety of sources. A couple of lines of R is all it takes to see that silver has had a very bad week.
For the past few meetings of the Greater Boston useR Group, we have been opened with an introductory “useR Vignette” talk on a topic which may be helpful for new R users. This week, I presented an overview of accessing databases from R. Several people have tweeted and blogged nice things about my talk and 
I found amazing R package in one of posts on R-bloggers website. It's called RcppAmadillo and you can find more info here. The function I am using from this package is called fastLm. Whereas I am interested in special case of Ax = b problem where A and...
(The examples here work with the version of insidefunctor tagged as "v2")
Unfortunately I couldn't do this cleanly outside the library. So the changes
are made in insidefunctor.
Levels are no longer used to "line up" eaches. So, for
example,
> library(insidefunctor)
> `%+.%` = fmap(`+`)
> `%/.%` = fmap(`/`)
> x = c(1,...
In my last post, I discussed the use of odds ratios to characterize the association between edibility and binary mushroom characteristics for the mushrooms characterized in the UCI mushroom dataset. I did not, however, describe those co...

The SAS Analysis blog post 'A macro calls R in SAS for paneled 3d plotting' influenced my macro coding. The following macro call: %EXPORT_TO_R(DATA = YOURDATA) exports the SAS data set 'YOURDATA' as .csv and produces the R code for se...
I developed the following schematic (with annotations) based on supporting documents (link) from the article cited below. The authors used R for their work. The ROC curve in my schematic was output from PROC LOGISTIC in SAS, the scatterplot with m...
