[R] Maintain proportions while reducing graphic output size

Hello, Is there a combination of par() settings or other commands that will allow me to uniformly reduce the size of graphics outputs? It appears that the png() device outputs 5-inch by 5-inch images, and I am trying to change my whole script to produce 4x4 images with the same proportions. I tri

[R] Difference in client vs. server graphics defaults

Hello, I am having trouble with the difference between default graphic settings on my client machine and the instance of R on our company's server. I created a script locally that output graphs, but when I run it on the server the output graphs have titles running past the margins, legends imprope

[R] SmoothScatter plot range issue

Hello, I am attempting to use smoothScatter to plot a heatmap of locations of events in an x-y axis. When I plot the heatmap without passing xlim and ylim parameters, it fills the plot area but the perspective is a bit skewed. I would like to standardize these plots to a uniform window size that d

[R] npc to native coordinates for xyplot

Hello, I am having trouble adding symbols to grid graphics. I am able to create a lattice scatterplot using xyplot, which has a range from -15:15 in both the X and Y directions. However, when I try to add circles and text to this graph using grid.circle() and grid.text(), they are offset using the

[R] Graphing: plot 3rd variable based on color gradient

Hello, I am searching for the best method to plot two variables with points whose output color depends on the size of a third variable. For example, the darkness of the x-y point would increase incrementally based on the size of the z value, similar to the colramp parameter in geneplotter. This wo
