mdaplotyy function

Create line plot with double y-axis

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

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.
