plotWithCircles {GCDkit} | R Documentation |
Plots a background binary diagram of two specified variables and the whole dataset or its selection. The size and colours of the plotted circles correspond to the third.
plotWithCircles(xaxis = "", yaxis = "", zaxis = "", colour = "heat.colors", scaling.factor = 1, bins = NULL, ident = getOption("gcd.ident"), alpha="FF")
xaxis |
Name of the data column to be used as x axis. |
yaxis |
Name of the data column to be used as y axis. |
zaxis |
Name of the data column to determine the size/colour of the circles. |
colour |
colour scheme for the circles. |
scaling.factor |
a factor determine the size of the circles. |
bins |
number of intervals for the legend. |
ident |
Logical: should be the individual samples identified? |
alpha |
hexadecimal number indicating the alpha channel (transparency). |
This function produces a custom binary plot, with the size and colours of the plotted circles corresponding to a third variable.
If no parameters 'xlab', 'ylab'
and 'zlab'
are given, the user is
prompted to specify them.
The variables are selected using the function 'selectColumnLabel
.
In the specification of the apices can be used also arithmetic expressions,
see calcCore
for the correct syntax.
The samples to be plotted can be selected based on combination of three searching
mechanisms (by sample name/label, range or a Boolean condition) - see selectSubset
for details.
The legal colour schemes are:
'"grays","reds","blues","greens","cyans","violets","yellows"
'"cm.colors","heat.colors","terrain.colors","topo.colors","rainbow", "jet.colors"
'.
Optionally, the colours can be made semitransparent, if hexadecimal parameter 'alpha'
is specified for the alpha channel (transparency).
None.
This function IS NOT Figaro-compatible.
