The reason is that I need to annotate the plot with something a little more elegant than arrows... I wrote the following function, which seems to work, bu...

Hello list, When using the grid package in R 1.60 under windows grid.lines and grid.line.to seem not to use the coordinate system as defined by the current viewport whereas grin.points does. Am I doing something wrong? Sten -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send

Am just feeling my way into the grid library, and cannot figure out how to define the plot limits. 3/5 of the example polygons below plot in the default 0-1 range viewport. But when I try to redefine the viewport the polygons plot in the same places. I also get the same result without employing push/pop. (As you can see from the scale I'm trying to introduce, I want to plot map polygons.)

Hello everybody, often I plot boxplots with different number of boxes (up to 200 boxes). I'd like to give every box a readable label on the x-axis. Therefore, I decrease the fontsize of the names and plot them vertical. But if you zoom into the plot (pdf) you will find an offset between the tickmark and the label - the label is shifted to the right. If you vary the box.count in the

...9; gpar; a line width multiplier. - grid.text() now handles any language object as mathematical annotation (instead of just expressions). - plotViewport() has default value for 'margins' argument (that match the default value for par(mar)). - The 'extension' argument to dataViewport() can now be vector, in which case the first value is used to extend the xscale and the second value is used to extend the y scale. (suggested by Ross Ihaka). - All 'just' arguments (for viewports, layouts, rectangles, text) can now be numeric values (typically between 0 [left...
