| assignColLab {GCDkit} | R Documentation |
Assigns plotting colours according to the levels of the chosen label or, alternatively, sample names.
assignColLab(lab = NULL, pal = NULL, colours = NULL, display.legend = FALSE)
lab |
specification of the variable to be used for colours assignment. See Details. |
pal |
character; name of the palette to be used when no colours are specified directly. Batch mode only. |
colours |
a vector with codes of colours to be assigned. Batch mode only. |
display.legend |
logical; should be the legend displayed? Batch mode only. |
If called from in interactive mode (from GUI), the variable (sample names or label)
can be selected using the function 'selectColumnLabel'.
In batch mode, 'lab' can be an integer (1 for sample names,
or a sequence number of the column in the 'labels' plus 1).
Alternatively, it can contain the full name of a column in 'labels'. See examples.
If in batch mode, either 'colours' or 'palette' have to be specified for the
correct colour assignment.
Sets 'leg.col' to a sequence number of column in 'labels' that is
to be used to build the legend or -1 if sample numbers are to be used;
'labels$Colour' contains the codes of the desired plotting colours.

To display the current legend use showLegend.
Symbols by a single label can be assigned by assignSymbLab,
symbols and colours by groups simultaneously by assignSymbGroup.
Uniform colours and symbols are obtained by assign1symb and
assign1col.
Table of available plotting symbols is displayed by showSymbols
and colours by showColours.
Selecting a label: selectColumnLabel.
Selecting a palette: selectPalette.
