read_roi_data: Read LANS data summary (.dac/.dat) files

In lans2r: Work with Look at NanoSIMS Data in R

Read LANS data summary (.dac/.dat) files

Description

Reads the ion data (.dac/.dat) files for the given LANS analysis folder and returns the ROIs data in a concatenated data frame with identifier columns 'ROI' and 'variable' (=ions). Note that this only reads ion data files by default and not any derived data files (any ratio or other formulas evaluated by LANS). If zstacks (i.e. individual planes) are exported from LANS, they can be loaded as well (and are by default). The resulting data frame has a 'plane' column that keeps track of the plane, the value 'all' identifies the combined data for the ROI from all planes.

Usage

read_roi_data(
  dat_folder,
  ion_data_only = TRUE,
  load_zstacks = TRUE,
  quiet = FALSE
)

Arguments

dat_folder	the LANS dat directory with the ions' .dac files
ion_data_only	by default TRUE, i.e. ignores all non-ion data files
load_zstacks	whether to load any z_stacks found, by default TRUE
quiet	whether to report information on the loaded data or not

Value

concatenated data_frame with all the ROIs' data, with identifier columns 'plane', 'ROI' and 'variable'
