grid: Internal Grid Extension

In NMF: Algorithms and Framework for Nonnegative Matrix Factorization (NMF)

Internal Grid Extension

Description

These functions enable mixing base and grid graphics in aheatmap, by avoiding calls to the grid internal function 'L_gridDirty'. They are not exported (i.e. not tampering core functions) and are only meant for internal use within the NMF package.

tryViewport tries to go down to a viewport in the current tree, given its name.

current.vpPath_patched aims at substituting current.vpPath, so that the graphic engine is not reset. This is essentially to prevent outputting a blank page at the beginning of PDF graphic engines.

.use.grid.patch tells if the user enabled patching grid.

Usage

  tryViewport(name, verbose = FALSE)

  current.vpPath_patched()

  .use.grid.patch()

Arguments

name	viewport name
verbose	toggle verbosity

Details

tryViewport uses grid.ls and not seekViewport as the latter would reset the graphic device and break the mix grid/base graphic capability.
