Examples

if (FALSE) {
# Remove all custom-defined spectral indexes from an options file

# Add a custom index for testing purposes
library(jsonlite)
opts_jsfile = system.file("testdata/test_addindex.json",
                             package = "MODIStsp")
 MODIStsp_addindex(
   opts_jsfile = opts_jsfile,
   gui = FALSE,
   new_indexbandname = paste0("Index_", as.character(sample(10000, 1))),
   new_indexformula = "b1_Red - b2_NIR",
   new_indexfullname = paste0("Index_", as.character(sample(10000, 1)))
   )

 opts <- jsonlite::fromJSON(indexes_file)
 opts$custom_indexes[1]

 # Now remove all custom indexes
 MODIStsp_resetindexes()
 opts <- jsonlite::fromJSON(opts_jsfile)
 opts$custom_indexes[1]
