Description Usage Arguments Details Value Author(s) References See Also Examples

Finds the number of sites of interest as well as other information from already calculated residence times.

1	Sites(Name, R, first = 'n', number_sites = -1)

`Name`	name of the data, which is used for any saved files and plot titles
`R`	radius value to use
`first`	if `'y'`, the algorithm will look for the second greatest maximum percent drop if the first results in the first circle being the only non-identified site
`number_sites`	number of sites to manually show the results for

This function finds all the necessary information from the results of the already applied algorithm Alt_Alg. It returns information relating to both the non-overlapping circles and also the identified sites, which is then used by other functions. The information is extracted from the already saved csv files.

sites_index - array of indices of the sites of interest among all the circles

N_no_overlap - number of non-overlapping circles

X_no_overlap - x-coordinates of non-overlapping circles

Y_no_overlap - y-coordinates of non-overlapping circles

X_sites - x-coordinates of identified sites of interest

Y_sites - y-coordinates of identified sites of interest

max_percent_drop - maximum percent drop

number_identified_sites - number of identified sites

psi_sort_no_overlap2 - ordered list of non-overlapping residence times

##Find the current working directory
wd = getwd()
##Set the working directory as the temporary one
setwd(tempdir())
##Set the working directory as the temporary one

##Load the data
data(OU_14)
t=unlist(OU_14["t"])
X=unlist(OU_14["X"])
Y=unlist(OU_14["Y"])

##Calculate the residence time with a radius of 0.3 and not including the first circle
Alt_Alg("OU_14",t,X,Y,0.3,first='y',save='y')

##Calculate all the necessary information to be used elsewhere
Sites("OU_14",0.3,first='y')

##Reset the original working directory
