Interactive plotting of graphs

tkplot() used to open an interactive Tcl/Tk window for drawing a graph. It is defunct since igraph 3.0.0 and throws an error when called. igraph has no interactive replacement: plot.igraph() draws a graph on any R graphics device, and rglplot() draws it in 3D.

tk_close(), tk_off(), tk_fit(), tk_center(), tk_reshape(), tk_postscript(), tk_coords(), tk_set_coords(), tk_rotate() and tk_canvas() acted on a window opened by tkplot(). As no such window can be opened any more, they have nothing to act on: tk_off() does nothing, and the others throw an error.

Usage

tkplot(graph, canvas.width = 450, canvas.height = 450, ...)

tk_close(tkp.id, ..., window.close = TRUE)

tk_off()

tk_fit(tkp.id, ..., width = NULL, height = NULL)

tk_center(tkp.id)

tk_reshape(tkp.id, newlayout, ..., params)

tk_postscript(tkp.id)

tk_coords(tkp.id, ..., norm = FALSE)

tk_set_coords(tkp.id, coords)

tk_rotate(tkp.id, ..., degree = NULL, rad = NULL)

tk_canvas(tkp.id)

Arguments

graph, canvas.width, canvas.height

Ignored, tkplot() is defunct.

...

Ignored by tkplot(). For tk_close(), tk_fit(), tk_coords() and tk_rotate(), these dots must be empty.

tkp.id

The ID of the tkplot window to close/reshape/etc.

window.close

Leave this on the default value.

width

The width of the rectangle for generating new coordinates.

height

The height of the rectangle for generating new coordinates.

newlayout

The new layout, see the layout parameter of tkplot.

params

Extra parameters in a list, to pass to the layout function.

norm

Logical, should we norm the coordinates.

coords

Two-column numeric matrix, the new coordinates of the vertices, in absolute coordinates.

degree

The degree to rotate the plot.

rad

The degree to rotate the plot, in radian.

Value

tkplot() throws an error.

tk_off() returns NULL invisibly. The other functions throw an error, as no plot with ID tkp.id exists.
