In mikemeredith/MMmisc: Stuff that Mike wants to have available

Convert coordinates from one Coordinate Reference System to another

1	convertCoords(coords, from = 4326, to)

`coords`	a two-column matrix or data frame with easting/longitude in the first column, northing/latitude in the second column
`from`	the EPSG code for the Coordinate Reference System of the input data (default WGS84)
`to`	the EPSG code for the CRS of the output data.

For EPSG codes, go to http://spatialreference.org/ref/epsg/ or just Google 'EPSG' with the desired CRS name.

The function requires the 'sp' and 'rgdal' packages.

A data frame or matrix with the converted coordinates.

# A matrix of coordinates
x <- cbind(c(0, 1, 4, 5), c(0, 1, 3, 1))
print(convertCoords(x, to=32631))  # UTM zone 31N
