DemoBoot {primer} | R Documentation |
This resamples three specific data sets and calculates demographic statistics and bootstrapped confidence intervals.
DemoBoot(stagedat = NULL, fruitdat = NULL, seeddat = NULL, n = 1)
stagedat |
A data frame identical in form to the data frame of the same name. |
fruitdat |
A data frame identical in form to the data frame of the same name. |
seeddat |
A data frame identical in form to the data frame of the same name. |
n |
Number of bootstrap replicates. |
This somewhat idiosyncratic function requires that the data frames have particular structures matching the data sets included in this package.
Returns a list of length n
, where each element is the output of a demographic analysis (see DemoInfo
).
