plotPlate {prada} | R Documentation |
Plot a well statistic in false color representation. The plot is supposed to resemble the physical geometry of a microtitre plate.
plotPlate(x, nrow=8, ncol=12, main, xrange, col, device, file, width, na.action="zero")
x |
Numeric vector of length ncol*nrow |
nrow |
Numeric of length 1. The number of rows of the plate. |
ncol |
Numeric of length 1. The number of columns of the plate. |
main |
Character of length 1. Plot title. This arguments gets passed
on to text as the argument labels . |
xrange |
Range of x that is mapped into the color scale. |
col |
Character vector. Usually the names of two or three colors
between which the color map is interpolated, using the function
colorramp . |
device |
Character. Name of a valid graphics device,
e.g. x11 , png , pdf . |
file |
The file argument of the call to
device , i.e. the name of the graphics output file. |
width |
The width argument of the call to
device , i.e. the width of the graphic. |
na.action |
Character. One of "zero" or "omit" .
How should the wells for which x is NA be treated?
For "zero" , they are plotted as if the value were 0.
For "omit" , they are omitted. |
The function produces a plot in the graphics device specified by the
device
argument.
It returns a list with two elements. The element which
is a vector with
the indices of those elements in x
that were plotted (see argument
na.action
). The element coord
is a length(which)
by 4
matrix in which each row specifies the corners of a rectangle that contains a
well. It is intended to be use as an argument to a subsequent call to
imageMap
.
