In vitorpaciello/Rsampleplot: Sample plots from a cartesian space and return descriptive statistics

Description

Draw n samples from data with elements in a cartesian coordinate system

Usage

SimulatePlots(plotdata, nsamples, dimx = NULL, dimy = NULL, nsims,
  xname = "gx", yname = "gy", species = "species", family = "family",
  biomass = "biomass", shape = c("rectangle", "circle"), size = c(5, 5),
  distance = 0, maxiter = 10^5)

Arguments

plotdata	a data frame with a forest plot census data.
nsamples	numeric value. The number of sample units.
dimx	numeric vector with two positions minimum and maximum value of the x coordinate.
dimy	numeric vector with two positions minimum maximum value of the y coordinate.
nsims	numeric value. The number of simulations.
xname	character string with the name of the x coordinate variable.
yname	character string with the name of the y coordinate variable.
species	character string with the name of the species variable.
family	character string with the name of the family variable.
biomass	character string with the name of the biomass variable.
shape	a character string. Two shapes are possible: "rectangle" and "circle"
size	numeric vector. For ”rectangle” the dimension of x and y sidesand for ”circle” the radius size.
distance	numeric value. The minimum distance among plots
maxiter	numeric value. indicating the maximum number of trails to sample units without overlaping.

Value

a data frame with the same columns as plotdata plus a 'sample' representing the sample unit number that the element are in.

Details

Draw sample from elements in a cartesian coordinate system and return the subset of data in the sample.

Examples

## Not run: 
data(bci7)
plotData <- RSamplePlots(bci7, nsamples = 100, shape = "circle", size = 10)

## End(Not run)
