Usage
## S3 method for class 'train':
plot(x,
plotType = "scatter",
metric = x$metric[1],
digits = getOption("digits") - 3,
xTrans = NULL,
nameInStrip = FALSE,
...)## S3 method for class 'train':
ggplot(data = NULL,
metric = data$metric[1],
plotType = "scatter",
output = "layered",
nameInStrip = FALSE,
...)
Arguments
x
an object of class train
. metric
What measure of performance to plot. Examples of possible values are "RMSE", "Rsquared", "Accuracy" or "Kappa". Other values can be used depending on what metrics have been calculated.
plotType
a string describing the type of plot ("scatter"
, "level"
or "line"
(plot
only))
digits
an integer specifying the number of significant digits used to label the parameter value.
xTrans
a function that will be used to scale the x-axis in scatter plots.
data
an object of class train
. output
either "data", "ggplot" or "layered". The first returns a data frame while the second returns a simple ggplot
object with no layers. The third value returns a plot with a set of layers.
nameInStrip
a logical: if there are more than 2 tuning parameters, should the name and value be included in the panel title?
