##### Boxplot bootstrap distributions

Boxplots for bootstrap distributions.

Keywords
models, regression
##### Usage
boxplots.bootpls(bootobject, indices = NULL, prednames = TRUE,
articlestyle = TRUE, xaxisticks=TRUE, ranget0= FALSE, las = par("las"),
mar, mgp, ...)
##### Arguments
bootobject

a object of class "boot"

indices

vector of indices of the variables to plot. Defaults to NULL: all the predictors will be used.

prednames

do the original names of the predictors shall be plotted ? Defaults to TRUE: the names are plotted.

articlestyle

do the extra blank zones of the margin shall be removed from the plot ? Defaults to TRUE: the margins are removed.

xaxisticks

do ticks for the x axis shall be plotted ? Defaults to TRUE: the ticks are plotted.

ranget0

does the vertival range of the plot shall be computed to include the initial estimates of the coefficients ? Defaults to FALSE: the vertical range is calculated only using the bootstrapped values of the statistics. Especially using for permutation bootstrap.

las

numeric in 0,1,2,3; the style of axis labels. 0: always parallel to the axis [default], 1: always horizontal, 2: always perpendicular to the axis, 3: always vertical.

mar

A numerical vector of the form c(bottom, left, top, right) which gives the number of lines of margin to be specified on the four sides of the plot. The default is c(5, 4, 4, 2) + 0.1.

mgp

The margin line (in mex units) for the axis title, axis labels and axis line. Note that mgp[1] affects title whereas mgp[2:3] affect axis. The default is c(3, 1, 0).

further options to pass to the boxplot function.
