Finding the Setpoint

You can find the setpoint and other information about an AFM image by retrieving the AFMinfo. Here is an example:

library(nanoscopeAFM)

# loading the test file from the nanoscopeAFM package
filename = (system.file("extdata","AR_20211011.ibw",package="nanoscopeAFM"))
# retrieving an AFMinfo object
h = AFMinfo(filename)

Basic information about an image can also be viewed, once you have an AFMinfo object:

# generate a summary of the AFMinfo object
summary(h)

Finding additional special information, using the function AFMinfo.item; note that the search string is case-sensitive.

sp =  AFMinfo.item(h, 'Setpoint')
print(paste("Setpoint:",sp,"V"))

The names of the items can be found with the same function; here is a list of the first few item names that can be used:

allNames = AFMinfo.item(h)
print(allNames[1:50])
