residual Plot
Produces a residual plot that shows the difference between the observed response and the fitted response values.
Examples
Parameters
The data to be displayed.
Name of independent variable.
Name of dependent variable that will be fitted.
default = "lm" ("lm", "loess", "lowess", "none"). Fitting method: "lm" (Linear Model) or "loess"/"lowess" (Locally Estimated Scatterplot Smoothing). If value of deg
parameter is greater than 1 then linear model becomes polynomial of the given degree. If method is "none" then data lives as is.
default = 1. Degree of polynomial for linear regression model.
default = 0.5. Only for "loess" method. The fraction of source points closest to the current point is taken into account for computing a least-squares regression. A sensible value is usually 0.25 to 0.5.
Random seed for "loess" sampling.
Maximum number of data-points for "loess" method. If this quantity exceeded random sampling is applied to data.
default = "point" ("point", "tile", "none"). The geometric object to use to display the data. No object will be used if geom="none"
.
Number or a Pair of Numbers. Number of bins in both directions, vertical and horizontal. Overridden by binWidth
. If only one value given - interpret it as list of two equal values. Applicable simultaneously for "tile" geom and "histogram" marginal.
Number or a Pair of Numbers. The width of the bins in both directions, vertical and horizontal. Overrides bins
. The default is to use bin widths that cover the entire range of the data. If only one value given - interpret it as list of two equal values. Applicable simultaneously for "tile" geom and "histogram" marginal.
Color of a geometry. For more info see: aesthetics.html#color-and-fill.
Size of a geometry.
Transparency level of a geometry. Understands numbers between 0 and 1.
Name of grouping variable.
default = true. false - do not show legend the main layer.
default = true. false - do not show horizontal line passing through 0.
default = "dens:r". Description of marginal layers packed to string value. Different marginals are separated by the ',' char. Parameters of a marginal are separated by the ':' char.
First parameter of a marginal is a geometry name. Possible values: "dens"/"density", "hist"/"histogram", "box"/"boxplot".
Second parameter is a string specifying which sides of the plot the marginal layer will appear on. Possible values: 't' (top), 'b' (bottom), 'l' (left), 'r' (right).
Third parameter (optional) is size of marginal. To suppress marginals use marginal="none"
.
Examples:
"hist:tr:0.3",
"dens:tr,hist:bl",
"box:tr:.05, hist:bl, dens:bl".
