greySet {StratigrapheR}

R Documentation

Sets the plot environment to draw a long vertical data set

Description

Sets the plot environment to draw a long dataset. It provides grey bands as supplementary scale, and axes with major and minor ticks.

Usage

greySet(
  xlim,
  ylim,
  xtick = NA,
  ytick = NA,
  nx = 1,
  ny = 1,
  xaxs = "i",
  yaxs = "i",
  xarg = list(tick.ratio = 0.5),
  yarg = list(tick.ratio = 0.5, las = 1),
  v = T,
  inverse = F,
  abbr = "",
  skip = 0,
  targ = list(col = "white", lwd = 2),
  rarg = list(border = NA, col = "grey85")
)

Arguments

`xlim`, `ylim`	the x and y limits (e.g. xlim = c(-1,1))
`xtick`, `ytick`	the interval between each major ticks for x and y
`nx`, `ny`	the number of intervals between major ticks to be divided by minor ticks in the x and y axes
`xaxs`, `yaxs`	The style of axis interval calculation to be used for the x and y axes. By default it is "i" (internal): it just finds an axis with pretty labels that fits within the original data range. You can also set it to "r" (regular): it first extends the data range by 4 percent at each end and then finds an axis with pretty labels that fits within the extended range. See ?par for further explanation
`xarg`, `yarg`	a list of arguments to feed to minorAxis() for the x and y axes. See the ?minorAxis help page for the possible arguments. See ?merge_list for further information.
`v`	whether the grey bands are vertical
`inverse`	inverse the bands position
`abbr`	text to be repeated in the grey bands each major tick
`skip`	number of text redundancies to be skipped
`targ`, `rarg`	a list of arguments to feed to text() and rect() respectively. If set to NULL, does not add the corresponding element.

Value

A plotting environment to draw a long data set

Examples

y <- c(0,11,19,33)
x <- c(1,2,2.5,4)

a <- min(y)
b <- max(y)

f<- encase(a-1,b,5)

greySet(c(0,4),f,abbr="abbr", ytick = 10, ny = 10)

points(x, y, pch=19)
