plotbyfactor {locfit} | R Documentation |
x-y scatterplot, colored by levels of a factor.
Description
Produces a scatter plot of x-y data, with different classes given
by a factor f. The different classes are identified by different
colours and/or symbols.
Usage
plotbyfactor(x, y, f, data, col, pch, add, lg,
xlab = deparse(substitute(x)),
ylab = deparse(substitute(y)), log = "", ...)
Arguments
x |
Variable for x axis.
|
y |
Variable for y axis.
|
f |
Factor (or variable for which as.factor() works).
|
data |
data frame for variables x, y, f. Default: sys.parent() .
|
col |
Color numbers to use in plot. Will be replicated if shorter than the
number of levels of the factor f. Default: 1:10 .
|
pch |
Vector of plot characters. Replicated if necessary. Default: O.
|
add |
If TRUE, add to existing plot. Otherwise, create new plot.
Default: FALSE .
|
lg |
Coordinates to place a legend. Default: Missing (no legend).
|
xlab |
label for x-axis. |
ylab |
label for y-axis. |
log |
which axis should be plotted in log scale ("x" ,
"y" , or "xy" .) |
... |
Other graphical parameters, labels, titles e.t.c. |
