nocturn just got published on CRAN!

nocturn is an online app and R package for sleep data analysis. It allows loading any type of data that is based on sleep sessions, whether it was produced by a radar device, actigraphy, sleep diary, or other.

You can access the nocturn app online at nocturn.bio.ed.ac.uk (no installation required). And if you want to write your own R scripts using nocturn, you can now install it directly from CRAN with:

install.packages("nocturn")

To use the package, load functions:

library(nocturn)

And display the package manual:

help(package = "nocturn")

Next steps

The current nocturn version on CRAN is 1.1.3. I am currently working on version 1.2.0, with some exciting updates to come:

• Comparison tool
  • Load multiple sessions files and compare them, e.g. with a Bland-Altman plot
• New sleep reports
  • Dataset comparison report
  • Report for actigraphy data
  • More customisation of text fields
• Save and load filter sets
  • Quickly apply a precise set of filters
  • Share with collaborators
  • Include with your data as documentation of your analysis process
• Enhanced in-app documentation
  • More tooltips explaining plots and options
