bedtext: Writes the names of the beds in a litholog

In StratigrapheR: Integrated Stratigraphy

Writes the names of the beds in a litholog

Description

Writes the names of the beds in a litholog. You can either place them at the centre of the beds or in their upper and lower part. You can also define a thickness below which the name won't be written, to avoid excessive text crowding the plot.

Usage

bedtext(
  labels,
  l,
  r,
  x = 0.2,
  arg = list(cex = 1),
  adj = c(0.5, 0.5),
  ymin = NA,
  edge = FALSE
)

Arguments

labels	the name of each bed
l	a vector of n left y (or dt, i.e. depth or time) interval limits for each bed
r	a vector of n right y (or dt, i.e. depth or time) interval limits for each bed
x	the position where to write the text (0.2 by default)
arg	a list of arguments to feed text(). Go see ?text to know which arguments can be provided. See ?merge.list for further information.
adj	one or two values in [0, 1] which specify the x (and optionally y) adjustment of the labels. c(0.5,0.5) is the default.
ymin	minimum thickness of the bed to write its name (if NA, a default value is calculated, but user input is best)
edge	whether to put the bed name at the edge of the beds (T) or in the center of the beds (F, is the default)

Examples

l  <- c(0,4,5,8)
r  <- c(4,5,8,16)

x   <- c(4,5,3,4)
i <- c("B1","B2","B3","B4")

test <- litholog(l, r, x, i)

whiteSet(xlim = c(0,6), ylim = c(-10,30))

multigons(test$i, test$xy, test$dt, col = c(NA, "black", "grey","NA"))

bedtext(labels = i, r = r, l = l, edge = TRUE, x = 0.5,
        arg = list(col = c("black", "white", "white", "red")))
