tableGrob and properties of a cell
Hello there,
could you please help to modify gpar() properties of a cell inside
tableGrob() output.
In the following example I want to have different color for one out of 4 cells
require(gridExtra)
z<-matrix(1:4,2,2)
grid.draw(tableGrob(z))
The only way I found for now how to do it is to do something like this
downViewport(current.vpTree()$children[[1]]$children[[6]]$name)

latex code in R -> convert to pdf
hi,
is it possible to convert latex code to pdf in R (like a latex-program

Is there a package that comes with this capabilities?

Besides latex ... are there good ways to generate tables in R?
thanks for any suggestions!

argument that gives the drawing details for each cell of the table.
Prototypes of two functions, 'tableplot' and 'cellgram' are given below.
The essential idea is that for a given table ('values'), the cells can be
