Arguments

data

a matrix, data frame or a list with data values (see details below).

groupby

one or several factors used to create groups of data matrix rows (works if data is a matrix)

type

type of the plot ('p', 'l', 'b', 'h', 'e').

pch

a character for markers (same as plot parameter).

lty

the line type (same as plot parameter).

lwd

the line width (thickness) (same as plot parameter).

cex

the cex factor for the markers (same as plot parameter).

col

colors for the plot series

bwd

a width of a bar as a percent of a maximum space available for each bar.

legend

a vector with legend elements (if NULL, no legend will be shown).

xlab

a title for the x axis (same as plot parameter).

ylab

a title for the y axis (same as plot parameter).

main

an overall title for the plot (same as plot parameter).

labels

what to use as labels ('names' - row names, 'indices' - row indices, 'values' - values).

ylim

limits for the y axis (if NULL, will be calculated automatically).

xlim

limits for the x axis (if NULL, will be calculated automatically).

colmap

a colormap to generate colors if col is not provided

legend.position

position of the legend ('topleft', 'topright', 'top', 'bottomleft', 'bottomright', 'bottom').

show.legend

logical, show or not legend for the data objects.

show.labels

logical, show or not labels for the data objects.

show.lines

vector with two coordinates (x, y) to show horizontal and vertical line cross the point.

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

tick values for x axis.

xticklabels

labels for x ticks.

yticks

tick values for y axis.

yticklabels

labels for y ticks.

show.excluded

logical, show or hide rows marked as excluded (attribute 'exclrows')

lab.col

color for data point labels.

lab.cex

size for data point labels.

xlas

orientation of xticklabels

ylas

orientation of yticklabels

opacity

opacity for plot colors (value between 0 and 1)

...

other plotting arguments.

Details

The mdaplotg function is used to make a plot with several sets of objects. Simply speaking, use it when you need a plot with legend. For example to show line plot with spectra from calibration and test set, scatter plot with height and weight values for women and men, and so on.

Most of the parameters are similar to mdaplot, the difference is described below.

The data should be organized as a list, every item is a matrix (or data frame) with data for one set of objects. Alternatively you can provide data as a matrix and use parameter groupby to create the groups. See tutorial for more details.

There is no color grouping option, because color is used to separate the sets. Marker symbol, line style and type, etc. can be defined as a single value (one for all sets) and as a vector with one value for each set.
