I have made a plot with a legend and on the screen it looks fine, but when I save as jpg or pdf, or print, the legend box is too small, it cuts through the words on the right side.

Hello! I first would like to compliment the authors of grid on what has been a wonderfully useful package for me. Now, my question: Is there any way I can specify the size of some grid.text using grid units? I must label the regions of a plot. The regions can be either very small or very large, so I would like to label each by fitting its text to the size of the region in question. Ideally, I

R users, I have a problem with function strwidth in 2.7.1. I'm trying to set the plot margins in a way that horizontal column labels will fit to the graph. tmp.t is a list of data.frame objects. This code works well in 2.6.0. ...snip.. library(gplots) for (i in names(tmp.t)) { bmp(filename=paste(i, "_", Sys.Date(), ".bmp", sep=""), width=1038,

How can I right justify the right-axis tick values? They appear in the example below as left-justified. I have tried several different ways and all fail in different ways. The example below creates the right axis tick value with no attempt at adjustment. alternates I have tried are 1. formatting the values. This doesn't work because they are in a proportional font and the blanks are too

...ut, I'm trying to find a clean and efficient way to arrange text grobs in a rectangular layout. The labels may be expressions, or text with a fontsize different of the default, which means that the cell sizes should probably be calculated using grobWidth() and grobHeight() as opposed to simpler stringWidth() and stringHeight(). (Correct?). The input of this function is a vector of labels, which are arranged into a matrix layout. Below is my current version, followed by a few questions. e = expression(alpha,"testing very large width", hat(beta), integral(f(x)*dx, a, b)) rowMax.units <-...
