Finds the nearest m/z peak to a given value in a SpaMTP Object
Usage
FindNearestMZ(data, target_mz, assay = NULL)
Arguments
- data
Seurat Spatial Metabolomic object containing mz values
- target_mz
Numeric value defining the target m/z peak
- assay
Character string indicating which Seurat object assay to pull data form. If set to NULL will use current default assay based on Seurat's DefaultAssay() function (default = NULL).
Value
String of the closest m/z value within the given dataset
Examples
utils::str(formals(FindNearestMZ))
#> Dotted pair list of 3
#> $ data : symbol
#> $ target_mz: symbol
#> $ assay : NULL
# FindNearestMZ(SeuratObj, target_mz = 400.01)
