ShinyChromViewer is an Shiny gadget for interactive viewing and exploration of 3D chromatographic data (e.g. from HPLC-DAD). It is mainly meant to be used in conjunction with chromatographR as an add-on.

ShinyChromViewer can be installed from GitHub as follows:

install.packages("devtools")
devtools::install_github("https://github.com/ethanbass/ShinyChromViewer/")

Or install directly from my R Universe repo:

install.packages("ShinyChromViewer", repos="https://ethanbass.r-universe.dev/", type="source")

To run ShinyChromConverter you must provide a list of chromatograms in matrix format. In addition, you can provide a peak_table object produced by chromatographR. The script below loads the example data from chromatographR and launches the chrom_viewer.

library(chromatographR)
library(ShinyChromViewer)
data(Sa_warp)
data(pk_tab)
chrom_viewer(pk_tab)

To view spectra, click on the trace plot (lower left panel) or the peak table (right panel).
