The reshape package is available on CRAN and can be installed using the R command install.packages("reshape"). This section will work through some techniques using the reshape package with an example data set (french fries). The data is from a sensory experiment investigating the effect of dif...

janitor has simple functions for examining and cleaning dirty data. It was built with beginning and intermediate R users in mind and is optimized for user-friendliness. Advanced R users can already do everything covered here, but with janitor they can do it faster and save their thinking for ...
SPSS favours this method for repeated-measures tests (such as repeated-measures ANOVAs or paired t-tests), and being able to move between the two formats is helpful when multiple people are working on a single dataset but using different packages (e.g., R vs SPSS). Get in Shape! The ...
Indeed, much of the code in the base and recommended packages in R is written in this way—the bulk of the code is in R but a few core pieces of functionality are written in C, C++, or FORTRAN. The type of code that benefits the most from this involves loops over data vectors. ...
Loading your data into R with rio packagesThe rio package is a relatively recent R package, developed by Thomas J. Leeper, which makes data import and export in R painless and quick.This objective is mainly reached when rio makes assumptions about the file format. This means that the rio ...
R packages have a 10MB size limit, at least onCRAN. BioconductorExperimentHubmay be able to support larger data packages. Sharing large volumes of raw data in an R package format is still not ideal, and there are public biological data repositories better suited for raw data: e.g.,GEO,SRA...
