Plot bootstrap confidence intervals

This function plots the confidence intervals derived using the function confints.bootpls from from a bootpls based object.

Keywords
models, regression
Usage
plots.confints.bootpls(ic_bootobject, indices = NULL, legendpos = "topleft", 
prednames = TRUE, articlestyle = TRUE, xaxisticks=TRUE, ltyIC=c(2, 4, 5, 1), 
colIC=c("darkgreen", "blue", "red", "black"), typeIC, las = par("las"), 
mar, mgp, ...)
Arguments
ic_bootobject

an object created with the confints.bootpls function.

indices

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

legendpos

position of the legend as in legend, defaults to "topleft"

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.

ltyIC

lty as in plot

colIC

col as in plot

typeIC

type of CI to plot. Defaults to typeIC=c("Normal", "Basic", "Percentile", "BCa") if BCa intervals limits were computed and to typeIC=c("Normal", "Basic", "Percentile") otherwise.

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 plot function.

Value

NULL
