plot_bar_chart: Plot the bar chart of residence times

Description

This function plots the bar chart of residence times with the ones that correspond to the sites of interest highlighted by a change in colour.

Usage

plot_bar_chart(Name, R, first='n', number_sites=-1, colours= c("red","darkgreen"))

Arguments

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

colours

list of the bars' colours

Value

Bar chart plot of the the residence times of non-overlapping circles

Details

Plots the bar chart of ranked residency times of non-overlapping circles. The percent drops are the relative differences between these consecutive bars and where the maximum percent drop occurs is identified using a change in colour between the bars. This plot can be used to see the percent drops visually and if the maximum percent drop can easily be identified by sight.

Examples

# NOT RUN {
##Find the current working directory
wd = getwd()
##Set the working directory as the temporary one
setwd(tempdir())
##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')

##Plot the bar chart of ranked non-overlapping residence times
plot_bar_chart("OU_14",0.3,first='y')

##It is possible to choose manually where the cut off between sites and none sites should be
plot_bar_chart("OU_14",0.3,first='y', number_sites=4)

##The colours can also be changed
plot_bar_chart("OU_14",0.3,first='y', colours = c("darkgreen","red"))

##Reset the original working directory
setwd(wd)
# }
