[R] Integration with LaTex and LyX

Hello, Are there any packages which allow for a good integration between R and LaTex / LyX? I'm interested mainly in automatic (automagic?) imports of plots/graphics. Thanks in advance and best regards, Eduardo de Oliveira Horta [[alternative HTML version deleted]]

Hi there, After many attempts at trying different methods I have used the Tps package to interpolate between a number of measurements of field data, in this case thickness of a sedimentary deposit. My input values are Longitude, Latitude and Thickness and I have produced a valid contour map base
