[R] Lattice xyplot: modify line width of plot lines
# Hi all,
# I want to increase the line width of the plotted lines
# in a xy-lattice plot. My own attempts were all in vain.
# Without the group option the line width is modified -
# with the option it is funnily enough not.
# Please have a look at my syntax.
#
# Many thanks in advance
# Udo
