| do3d {made4} | R Documentation |
do3d is a wrapper for scatterplot3d. do3d will draw a single 3D xyz
plot and will plot each group of points in a different colour, given a
factor.
rotate3d calls do3d to draw multiple 3D plots in which each plot is
marginally rotated on the x-y axis.
do3d(dataset, x = 1, y = 2, z = 3, angle = 40, classvec = NULL, classcol = NULL, col = NULL, cex.lab=0.3, pch=19, cex.symbols=1, ...) rotate3d(dataset, x = 1, y = 2, z = 3, beg = 180, end = 360, step = 12, savefiles = FALSE, classvec = NULL, classcol = NULL, col = NULL, ...)
dataset |
XYZ coordinates to be plotted. A matrix or data.frame
with 3 or more columns. Usually results from multivariate analysis, such as the $co or $li coordinates
from a PCA dudi.pca, or COA
dudi.coa or the $ls, $co coordinates from
bga. |
x |
Numeric, the column number for the x-axis, the default is 1 (that is dataset[,1]) |
y |
Numeric, the column number for the y-axis, the default is 2 (that is dataset[,2]) |
z |
Numeric, the column number for the z-axis, the default is 3 (that is dataset[,3]) |
angle |
Numeric, the angle between x and y axis. Note the result depends
on scaling. See scatterplot3d |
classvec |
A factor or vector which describes the classes in dataset |
classcol |
A factor or vector which list the colours for each of the classes
in the dataset. By default NULL. When NULL, getcol is used to
obtain an optimum set of colours of the classes in classvec. |
cex.lab |
Numeric. The magnification to be used for the axis annotation relative to the current default text and symbol size. Default is 0.3 |
pch |
Integer specifying a symbol or single character to be used when plotting points. The default is pch= 19 |
cex.symbols |
Numeric. The magnification to be used for the symbols relative to the current default text size. Default is 1 |
col |
A character indicating a colour. To be used if all points are to be one colour. If classvec, classcol and col are all NULL. all points will be drawn in red by default. |
beg |
Numeric. The starting angle between the x and y axis for rotate3d. Rotate3d will draw plots in which they are rotated from angle beg to angle end |
end |
Numeric. The final angle between the x and y axis for
rotate3d. Rotate3d will draw plots in which they are
rotated from angle beg to angle end |
step |
Numeric. Increment of the sequence between the starting angle beg and the final angle end. |
savefiles |
Logical, indicating whether the plot should be saved as a pdf file. The default is FALSE |
... |
further arguments passed to or from other methods |
Produces plots of the xyz coordinates.
