2-D scatter plot with trajectories
This function represents a two dimensional scatter plot with trajectories.
s.traject(dfxy, fac = gl(1, nrow(dfxy)), order, labels = levels(fac), xax = 1, yax = 2, col = NULL, facets = NULL, plot = TRUE, storeData = TRUE, add = FALSE, pos = -1, ...)
dfxy |
a data frame used to produce the plot |
fac |
a factor (or a matrix of factors) splitting the rows of |
order |
a vector containing the drawing order of the trajectories. A vector of length equal to factor. |
labels |
a vector of character strings containing the trajectories' labels |
xax |
an integer (or a vector) indicating which column(s) of |
yax |
an integer (or a vector) indicating which column(s) of |
col |
a color or a colors vector to color points, labels and lines |
facets |
a factor splitting the rows of |
plot |
a logical indicating if the graphics is displayed |
storeData |
a logical indicating if the data should be stored in
the returned object. If |
add |
a logical. If |
pos |
an integer indicating the position of the
environment where the data are stored, relative to the environment
where the function is called. Useful only if |
... |
additional graphical parameters (see

The fac factor is used to display several trajectories: each level of fac is a specific trajectory.
An object of class ADEg (subclass S2.traject) or ADEgS (if add is TRUE and/or
if facets or multidimensional fac or vectors for xax/yax are used).
The result is displayed if plot is TRUE.
