There are six pre-described line types available in base R. You can use those for any type of graphics, like plotting for line charts... The post Line types in R: Ultimate Guide For R Baseplot and ggplot appeared first on finnstats.

There are four types of hosting patterns for Shiny apps: local, dockerized, Shiny Server, and Shiny Server inside Docker. Here is what you need to know if you want to self-host Shiny apps.

Many statistical learning algorithms perform better when the covariates are on similar scales. For example, it is common practice to standardize the features used by an artificial neural network so that the gradient of its objective function doesn’t depend on the physical units in which the features are described. ...

An important aspect of maintaining databases with an application interface is to ensure atomicity. When performing multiple writes on a database, any failures that occur during the operations should not violate any logical rules. The most common analogy is a financial transaction. If person A withdraws X dollars from their ...

The use of geospatial data – data that can be mapped using geographic information systems (GIS) – has become increasingly widespread in the social sciences. Applications not only extend to the analysis of classical geographical entities (e.g., policy diffusion across spatially proximate countries) but increasingly also to analyses of micro-level data, ...

tl;dr: To avoid triple quotes and R CMD CHECK --as-cran errors due to documentation examples for internal functions, enclose the example code in \dontrun{}. I recently encountered an issue when submitting an R package to CRAN that I couldn’t find … Continue reading →

parallelly 1.26.0 is on CRAN. It comes with one major improvement and one new function: The setup of parallel workers is now much faster, which comes from using a concurrent, instead of sequential, setup strategy The new freePort() can be used to...

Kendall’s Rank Correlation in R, Kendall’s rank correlation coefficient is suitable for the paired ranks as in the case of Spearman’s rank correlation. The... The post Kendall’s Rank Correlation in R-Correlation Test appeared first on finnstats.

The dockerized Shiny Server is a heavyweight hosting option that plays an important role in the Shiny hosting landscape.

In two previous posts, Introduction to Functional Data Analysis with R and Basic FDA Descriptive Statistics with R, I began looking into FDA from a beginners perspective. In this post, I would like to continue where I left off and investig...

In recent years, a surprising number of scientific results have failed to hold up to continued scrutiny. Part of this ‘replicability crisis’ may be caused by practices that ignore the assumptions of traditional (frequentist) statistical methods (John, Loewenstein, and Prelec 2012). One of these assumptions is that the experimental protocol should ...

Thanks to my answering a (basic) question on X validated involving an R code, R mistakes and some misunderstanding about Bayesian hierarchical modelling, I got pointed out to Patrick Burns’ The R inferno. This is not a recent book as the second edition is of 2012, with a 2011 version still available ...

A working paper describing the data and methods used for our probabilistic UEFA Euro 2020 forecast, published earlier this week, is available now. Additionally, details on the predicted performance of all teams during the group stage are prov...
