Plot Multiple Lines
Description
Plots multiple lines based on a vector x
and a matrix y
,
draws thin vertical lines connecting limits represented by columns of
y
beyond the first. It is assumed that either (1) the second
and third columns of y
represent lower and upper confidence
limits, or that (2) there is an even number of columns beyond the
first and these represent ascending quantiles that are symmetrically
arranged around 0.5.
Usage
multLines(x, y, pos = c('left', 'right'), col='gray',
lwd=1, lty=1, lwd.vert = .85, lty.vert = 1,
alpha = 0.4, grid = FALSE)
Arguments
