mdaplotyy: Create line plot with double y-axis

In mdatools: Multivariate Data Analysis for Chemometrics

Create line plot with double y-axis

Description

mdaplotyy create line plot for two plot series and uses separate y-axis for each.

Usage

mdaplotyy(
  data,
  type = "l",
  col = mdaplot.getColors(2),
  lty = c(1, 1),
  lwd = c(1, 1),
  pch = (if (type == "b") c(16, 16) else c(NA, NA)),
  cex = 1,
  xlim = NULL,
  ylim = NULL,
  main = attr(data, "name"),
  xlab = attr(data, "xaxis.name"),
  ylab = rownames(data),
  labels = "values",
  show.labels = FALSE,
  lab.cex = 0.65,
  lab.col = "darkgray",
  show.grid = TRUE,
  grid.lwd = 0.5,
  grid.col = "lightgray",
  xticks = NULL,
  xticklabels = NULL,
  xlas = 0,
  ylas = 0,
  show.legend = TRUE,
  legend.position = "topright",
  legend = ylab,
  ...
)

Arguments

data	a matrix or a data.frame with two rows of values.
type	type of the plot ("l" or "b").
col	a color for markers or lines (same as plot parameter) for each series.
lty	line type for each series (two values)
lwd	line width for each series (two values)
pch	a character for markers (same as plot parameter) for each series (two values).
cex	scale factor for the markers
xlim	limits for the x axis (if NULL, will be calculated automatically).
ylim	limits for the y axis, either list with two vectors (one for each series) or NULL.
main	an overall title for the plot (same as plot parameter).
xlab	a title for the x axis (same as plot parameter).
ylab	a title for each of the two y axis (as a vector of two text values).
labels	a vector with text labels for data points or one of the following: "names", "indices", "values".
show.labels	logical, show or not labels for the data objects.
lab.cex	size for data point labels.
lab.col	color for data point labels.
show.grid	logical, show or not a grid for the plot.
grid.lwd	line thinckness (width) for the grid.
grid.col	line color for the grid.
xticks	values for x ticks.
xticklabels	labels for x ticks.
xlas	orientation of xticklabels.
ylas	orientation of yticklabels (will be applied to both y axes).
show.legend	logical show legend with name of each plot series or not
legend.position	position of legend if it must be shown
legend	values for the legend
...	other plotting arguments.

Details

This plot has properties both mdaplot and mdaplotg, so when you specify color, line properties etc. you have to do it for both plot series.
