Functions to calculate subplot index, code and coordinates

Description

'splitPlot' create a code for subquadrats of any dimension

Usage

splitPlot(dx, dy, splitX = 5, splitY = splitX, maxX = 20, maxY = maxX)

subplotXY(
  xcode = LETTERS[1:16],
  ycode = c(paste(0, 0:9, sep = ""), 10:15),
  xsub = 20,
  ysub = 20
)

xyMin(subplot_code, xymin = subplotXY())

splitPlotXY(subplotxy, splitX = 5, splitY = splitX, maxX = 20, maxY = maxX)

splitPlotData(
  censoData,
  subplotCodes,
  splitQuadXY,
  buffer = 2,
  dbh = "dbh",
  gx = "gx",
  gy = "gy",
  status = "status19"
)

Arguments

dx	x coordinate for subplot
dy	y coordinate inside subplots
splitX	x size of subquadrats
splitY	y size of subquadrats, default equal do 'splitX'
maxX	maximum potential value for 'dx'
maxY	maximum potential value for 'dy'
gx	x coordinate for the all plot
gy	y coordinate for the all plot
sub.size	size of the subplots
max.x	maximum x coordinate
max.y	maximum y coordinate
plot.code	subplot codes

Details

'subplotXY' calculate the x and y coordinates for subplots

'xyMin' calculate x and y coordinates for a vector of suplots

'subplotIndex' calculate x and y coordinates for a vector of suplots

Value

return a new coordinates gx and gy or plot code in the format '0x0' representing origin for subplot

xcode <-  LETTERS[1:16]
ycode <-  c(paste(0, 0:9, sep = ""), 10:15)
xyMin(subplot_code = paste(sample(xcode, size = 25, replace = TRUE), sample(ycode, size = 25, replace = TRUE), sep = ""))
