# mbr
[](https://github.com/mdsumner/mbr/actions)
The goal of mbr is to compute the minimum bounding rectangle of a set of points.
Provided as an answer to a question on this site, by Bill Huber on 2012-04-05
https://gis.stackexchange.com/questions/22895/finding-minimum-area-rectangle-for-given-points/22934?stw=2#22934
Here is an example of its use:
```{r mbr}
library(mbr)
# Create sample data
set.seed(23)
p <- matrix(rnorm(20*2), ncol=2) # Random (normally distributed) points
mbr <- MBR(p)
# Plot the hull, the MBR, and the points
limits <- apply(mbr, 2, range) # Plotting limits
plot(p[(function(x) c(x, x[1]))(chull(p)), ],
type="l", asp=1, bty="n", xaxt="n", yaxt="n",
col="Gray", pch=20,
xlab="", ylab="",
xlim=limits[,1], ylim=limits[,2]) # The hull
lines(mbr, col="Blue", lwd=3) # The MBR
points(p, pch=19)
```
