A major update of spaCy (v2.1) was released recently. spaCy is one of the best and fastest tools for tokenization, part-of-speech tagging, dependency parsing, and entity recognition. In this post, I will discuss how it works with our spacyr package along with some tips on having multiple versions of spaCy ... [Read more...]

Psychological science is still massively using analysis of variance (ANOVA). Despite its relative simplicity, I am very often confronted to errors in its reporting, for instance in student’s theses or manuscripts, or even published papers (See the excellent statcheck to quickly check the stats of a paper). Beyond the ... [Read more...]

One of the most time-consuming part of data analysis in science is the copy-pasting of specific values of some R output to a manuscript or a report. This task is frustrating, prone to errors, and increases the variability of statistical reporting. At the sime time, standardizing practices of what and ... [Read more...]

or more precisely union many spatial tables in R in a tidy way. dplyr::bind_rows doesn’t work on sf objects ; base::rbind only work on two tables and so that’s not straightforward to use*. So we’ll use purrr::map and tidyr::unnest. First get some data, ... [Read more...]

Although SAS is the main player in the pharmaceutical industry, R is gaining popularity. In this post I will just mention some initiatives, documents and podcast episodes dealing with using R in pharmaceutical research and development programs. Recently, it was a pleasure to listen the episode of the Effective Statistician ... [Read more...]

In my previous post (https://statcompute.wordpress.com/2019/03/10/a-summary-of-my-home-brew-binning-algorithms-for-scorecard-development), I’ve shown different monotonic binning algorithm that I developed over time. However, these binning functions are all useless without a deployment vehicle in production. During the weekend, I finally had time to draft a R function (https://github.com/statcompute/...

I’ve just updated the GitHub’s version of BCEA. Andrea has done, as usual, some very nice work – this time he’s mainly focussed on the graphical engine underlying the graphs produced by BCEA to post-process the outcome of the economic model. The main changes are the following: Added ... [Read more...]

We all work with data frames and it is important that we know how we can reshape them, as necessary to meet our needs. I think that there are, at least, four routine tasks that we need to be able to accomplish: subsetting sorting casting melting Obviously, there is a ... [Read more...]

tl;dr In many areas, multiple data sets need to be combined before data can be analysed. An example of this is experimental data in the field of psychology, where a data file is produced for each participant. This blog post (actually a video), introduces multi-file import available in the 0.9.6 ... [Read more...]
