string_del	Optional argument. Indicates pattern in the specimens names to be deleted. Use only if ID = NULL.
save.txt	Optional argument. Indicates whether to also save *.txt files with the landmark coordinates.

Examples

# array <- drishti2array()
# If we have files with the suffix "_skull"
# For example: "spec1_skull", "spec2_skull", "spec3_skull", etc.
# Make sure that the files
# dir <- "~/Documents/skull_LMs")
# skull_array <- drishti2array(dir = skull_dir, string_del="_skull", save.tag = TRUE) # will save *.tag landmark files
