l_loonWidgets {loon}

Get all active top level loon plots.

Description

Loon's plots are constructed in TCL and identified with a path string appearing in the window containing the plot.

If the plots were not saved on a variable, this function will look for all loon plots displayed and return their values in a list whose elements may then be assigned to R variables.

Usage

l_loonWidgets(pathTypes, inspector = FALSE)

Arguments

pathTypes

an optional argument identifying the collection of path types that are to be returned (if displayed).

inspector

whether to return the loon inspector widget or not

This must be a subset of the union of l_basePaths() and l_compoundPaths().

If it is missing, all l_basePaths() and l_compoundPaths() will be returned.

Value

list whose elements are named by, and contain the values of, the loon plot widgets. The list can be nested when loon plots (like l_pairs) are compound in that they consist of more than one base loon plot.

Examples

if(interactive()){
l_plot(iris)
l_hist(iris)
l_hist(mtcars)
l_pairs(iris)
# The following will not be loonWidgets (neither is the inspector)
tt <- tktoplevel()
tkpack(l1 <- tklabel(tt, text = "Heave"), l2<- tklabel(tt, text = "Ho"))
#
# This will return loon widgets corresponding to plots
loonPlots <- l_loonWidgets()
names(loonPlots)
firstPlot <- loonPlots[[1]]
firstPlot["color"] <- "red"
histograms <- l_loonWidgets("hist")
lapply(histograms,
       FUN  = function(hist) {
                hist["binwidth"] <- hist["binwidth"]/2
                l_scaleto_world(hist)
             }
             )
