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 = 1:10, pch = "O", add = FALSE, 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.
|
lg |
Coordinates to place a legend. Default: Missing (no legend).
|
xlab, ylab |
Axes labels. |
log |
Should the axes be in log scale? Use "x" , "y" ,
or "xy" to specify which axis to be in log scale. |
