I'd like to generate some square plots that have arrays of hexagons inside of them, like drawn here. I'd like to plot both regular (geometrically regular) and abnormal hexagon tessellations, so I d...

I have 2 vectors: set.seed(1) x1 = rnorm(100,0,1) x2 = rnorm(100,1,1) I want to plot these as lines and then find the intersection points of the lines, also if there are multiple points of inter...

I'm using runifdisc to plot random points on a disc, but I don't want those points to land within a certain proximity of the other points. The points are currently parsed into squares and triangles...

I have data in the form (x, y, z) where x and y are not on a regular grid. I wish to display a 2D colormap of these data, with intensity (say, grey scale) mapped to the z variable. An obvious solut...

I am doing some work where I need to generate both a) random spatial points b) non-random spatial points, over a polygon i.e. for b) the points probability depends on for example an East-West gradi...

I am trying to create Voronoi polygons (aka Dirichlet tessellations or Thiessen polygons) within a fixed geographic region for a set of points. However, I am having trouble finding a method in R th...

I'm trying to find the euclidean distance between two points, confined by an irregular polygon. (ie. the distance would have to be calculated as a route through the window given) Here is an reprod...

In the R package spatstat (I am using the current version, 1.31-0) , there is an option use.gam. When you set this to true, you can include smooth terms in the linear predictor, the same way you do...
