EGM (development version)

• Updates to {pkgdown} settings for documentation organization
• Debugging the color issues when adding a color theme to ggm()
• Creation of subclass of egm objects called ecg to identify 12-lead ECG subtypes

EGM 0.1.1

This is an updated release to CRAN for this package. The changes to this version are as follows.

• Update to ggm() function to allow for appropriate theming for dark and light color themes (removes issues with importing colors)

• Update to code and testing suite to assess compatibility with the {ggplot2} v4.0.0 release

• Addition of a series of functions for F wave extraction and analysis

• Addition of rudimentary functions for windowing signal based on surface ECG

• New function to read in Prucka (CardioLab) for EP study recordings with the read_prucka() function

EGM 0.1.0

This is the first CRAN release for this package. The initial version contains key features for working with intracardiac electrograms (EGM) and surface electrocardiograms (ECG), visualizing signals, and working with annotations stored in the WFDB format. A single, major class is introduced here.

• egm objects contain signal data and meta-data with specific dispatch methods, and are composed of three internal classes
  • a signal_table that contains the raw signal data
  • a header_table that contains meta-data about the signal data
  • an annotation_table that identifies samples and labels them with specific annotations

Additional I/O features are introduced to work with data stored in the WFDB format:

• read_wfdb() reads in WFDB data and returns an egm object
• write_wfdb() writes an egm object to a WFDB-compatible format

This first version also allows working with ECG and EGM data using:

• read_muse() for ECG data (GE MUSE, v9)
• read_lspro() for EGM data (LabSystem Pro)

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
