Get AFMdata object type: image, frequency, force, spectroscopy

Source: R/AFMdata.R

Determine the type of the AFM file; this could be an `image` or `frequency` for resonance curve, or `spectroscopy` for a force vs distance spectroscopy file, `noImage` for a file with data and no image

AFM.dataType(obj)

Arguments

obj

AFMdata object

Value

string with AFM type, "image", "noImage", "frequency", "spectroscopy"

Examples


# show the data type for each AFM file
fList = AFM.getSampleImages()
sapply(fList, function(x) { AFM.dataType(AFM.import(x)) })
