drawable.list-class: Class
Description
The purpose of this class is to store and manage a collection of tk.browse and browsePlot as input. Objects can be created by the drawable.list constructor, and edited / created using the tk.tracks Tcl-tk interface. By default, the drawable.list$add() method is only able to handle objects from drawableFromFile.EXTENSION and drawableFromClass.CLASS, in the global environment or a package. Such a function will take the same arguments as the drawable.list$add() method, and will only have to return a Extends
All reference classes extend and inherit methods from Fields
classes:- Read-only, returns a vector of
objects classes.
count:- Read-only, returns the length of
objects, as a single integer.
files:- Character vector, the paths where each drawable object is to be stored.
hidden:- Logical vector, whether each object is to drawn or hidden in plots.
names:- Read-only, returns a vector of
objects 'name' fields.
objects:- List of
Methods
add(file, track = , hidden = , ...):-
Add a track to the list.
- file : single character value, the path to the file containing the 'drawable' object to add.
- track : a 'drawable' object to add. If NULL, will be extracted from 'file'.
- hidden : single logical value, whether the track is to be shown on plots or hidden. This value can be changed later.
- ... : further arguments to be passed to drawableFromFile.EXTENSION or drawableFromClass.CLASS, if relevant.
check(warn = ):-
Raises an error if the object is not valid, else returns TRUE
fix.files(parent = ):-
Edit drawable list using a Tcl-tk GUI
- parent : tcltk parent frame for inclusion, or NULL.
fix.param(selection = , parent = ):-
Edit drawing parameters using a Tcl-tk GUI
- selection : single integer value, the position of the track selected in the list.
- parent : tcltk parent frame for inclusion, or NULL.
get(index, what = ):-
Returns a single 'what' from the series
- index : single numeric value, the position of the track to get.
- what : single character value, the field to be exracted.
getByClasses(classes, what = ):-
Returns a subset of 'what' from the series, querying by class inheritance
- classes : character vector, the class names of the objects to get (inheriting classes are picked too).
- what : single character value, the field to be exracted.
getByNames(names, what = ):-
Returns a subset of 'what' from the series, querying by track name
- names : character vector, the names of the objects to get.
- what : single character value, the field to be exracted.
getByPositions(positions, what = ):-
Returns a subset of 'what' from the series, querying by position
- positions : integer vector, the positions of the objects to get.
- what : single character value, the field to be exracted.
getChromEnd(chrom):-
Returns as a single integer value the maximal ending position of the object descriptions of the given chromosome.
- chrom : single integer, numeric or character value, the chromosomal location.
,
initialize(files = , objects = , hidden = , ...):moveDown(toMove):-
Increases the position of a track, switching position with the next one
- toMove : single numeric value, the position of the track to move.
moveUp(toMove):-
Decreases the position of a track, switching position with the previous one
- toMove : single numeric value, the position of the track to move.
remove(toRemove):-
Remove one or many tracks from the list
- toRemove : numeric vector, the positions of the tracks to remove.
