plot.mat {analogue}  R Documentation 
Five plots (selectable by which
) are currently available: a
plot of estimated against observed values, a plot of residuals against
estimated values, and screeplots of the apparent RMSE, average bias
and maximum bias for MAT models of size k, where k = 1,
…, n. By default, the first three and ‘5’ are provided.
## S3 method for class 'mat' plot(x, which = c(1:3, 5), weighted = FALSE, k, caption = c("Inferred vs Observed", "Residuals vs Fitted", "Leaveoneout errors", "Average bias", "Maximum bias"), max.bias = TRUE, n.bias = 10, restrict = 20, sub.caption = NULL, main = "", ask = prod(par("mfcol")) < length(which) && dev.interactive(), ..., panel = if (add.smooth) panel.smooth else points, add.smooth = getOption("add.smooth"))

This plotting function is modelled closely on plot.lm
and many of the conventions and defaults for that function are
replicated here.
sub.caption
 by default the function call  is shown as a
subtitle (under the xaxis title) on each plot when plots are on
separate pages, or as a subtitle in the outer margin (if any) when
there are multiple plots per page.
One or more plots, drawn on the current device.
