redsquirrels: Kluane Red Squirrel Data

Description

A tidy data frame of life‐history and reproductive metrics for 7,799 individual red squirrels from the Kluane Red Squirrel Project (1987–present).

Usage

data(redsquirrels)
data(redsquirrels_full)

Format

## `redsquirrels_full` A data frame with 7799 rows and 16 columns:

personID

Unique identifier for each squirrel

momID, dadID

Unique identifiers for each squirrel's parents

sex

Biological sex of the squirrel

famID

Unique identifier for each family. Derived from ped2fam

byear

Birth year of the squirrel

dyear

Death year of the squirrel

lrs

lifetime reproductive success for the squirrel

ars_mean

Mean annual reproductive success for the squirrel

ars_max

Maximum ARS value for the squirrel

ars_med

Median ARS value for the squirrel

ars_min

Minimum ARS value for the squirrel

ars_sd

Standard deviation of ARS values for the squirrel

ars_n

Number of ARS values for the squirrel

year_first

First year of ARS data for the squirrel

year_last

Last year of ARS data for the squirrel

...

## `redsquirrels` A data frame with 5251 rows and 16 columns: A subset of redsquirrels_full intended for convenient analysis and examples. (Same variables as redsquirrels_full, with fewer rows.)

An object of class tbl_df (inherits from tbl, data.frame) with 7799 rows and 16 columns.

Details

#' This package provides two related datasets:

• redsquirrels_full: the complete dataset from the published source

• redsquirrels: a more workable subset derived from redsquirrels_full

Each row corresponds to one squirrel with associated pedigree links and reproductive success summaries.
