Description Usage Arguments Details Value Examples
Provide various summaries for an event-level dataset, including estaimtes and plots.
1 2 | acme.summary(fname, spec = "", blind = TRUE, ps = "", plot_scav = FALSE,
plot_srch = FALSE)
|
fname |
Data, either a string for csv files or a data frame name |
spec |
Species subset. Default (empty string) includes all species in data set. |
blind |
Logical. If TRUE, assumes FT are unaware of carcasses. |
ps |
Character string, name of Postscript file generated. Default (empty string) displays plots on console and does not generate postscript file. |
plot_scav |
Logical. If TRUE, persistence plot is output. Default is FALSE. |
plot_srch |
Logical. If TRUE, search efficiency plot is output. Default is FALSE. |
This function takes in an event-level dataset of placement and searches, and reports various statistics related to ACME. This includes empirical information such as search intervals, carcass information summaries, and available scavenger information. This function also reports on estimated values R* and bleed-through rate. All information is printed to the console.
Users have the option of creating plots of empirical data overlayed on estimated distributions for both persistance and search efficiency.
acme.summary
returns a list with the following components:
params |
5-element vector: alpha and rho parameters for the Weibull persistence distribution, a and b parameters for the exponentially decreasing search proficiency, and bt as the bleed-through parameter. |
Rstar |
Reduction factor (inverse of the inflation factor for mortality counts). |
T |
First component of R* - carcass fraction found on first search. |
I |
Average interval length, in days. |

acme.summary('altamont.csv', spec = "BHCO")
#To include plots
