When using ggplot in R, how do I remove margins surrounding the plot area?

I\'m trying to generate some fractals and have a question regarding the margins with ggplot in R. I\'m using the following code to generate the fractals.

Answer 1

I was able to get rid of the white border by setting negative plot margins and setting the axis titles to NULL. I've marked the edits in the code below.

p = ggplot(data=df, aes(V1, V2, color=cl[V3]))+ 
  geom_point() + 
  theme(panel.background=element_blank(), 
        panel.grid.major=element_blank(), 
        panel.grid.minor=element_blank(), 
        panel.margin = unit(c(0, 0, 0, 0), "cm"),       
        axis.ticks=element_blank(), 
        axis.text.x=element_blank(), 
        axis.text.y=element_blank(), 
        axis.title.x=element_blank(), 
        axis.title.y=element_blank(),
        plot.background = element_rect(fill = "transparent",colour = NA),
        plot.margin = unit(c(-1, -1.2, -1.2, -1.5), "cm"),  # Edited code
        legend.position = 'none') +
  labs(x=NULL, y=NULL) # New code
