From hexbin v1.29.0
by Nicholas LewinKoh

##### Compute X and Y Coordinates for Hexagon Cells

Computes x and y coordinates from hexagon cell id's.

- Keywords
- manip

##### Usage

`hcell2xy(hbin, check.erosion = TRUE)`

##### Arguments

- hbin
- a object of class
`"hexbin"`

, typically produced by`hexbin(*)`

. - check.erosion
- logical indicating if only the eroded points
should be returned in the case where
`hbin`

inherits from`"erodebin"`

(see`erodebin-class`

); is`TRUE`

by default.

##### Details

The hexbin object `hbin`

contains all the needed information.
The purpose of this function is to reduce storage. The cost is
additional calculation.

##### Value

- A list with two components of the same length as
`bin$cell`

, x y

##### Examples

```
x <- rnorm(10000)
y <- rnorm(10000)
plot(x,y, pch=".")
hbin <- hexbin(x,y)
str(xys <- hcell2xy(hbin))
points(xys, cex=1.5, col=2) ; title("hcell2xy( hexbin(..) )", col.main=2)## Temporal trends with confidence bounds plotted on a map:
## <NOT YET> Illustration only pending access to user functions
## mtapply() # like tapply but for matrices
## sens.season.slope() # computes sen's seasonal slope
## This part does not work and commented out
#hbin <- hcell(dat$x,dat$y) # x and y are in map projection units
#newdat < dat[,c('month','year','value')] # extract columns
#stats <- mtapply(newdat,bin$cell,sens.season.slope,season=12)
#plot(mymap,type='l') # map boundaries in map projection units
#xy <- hcell2xy(hbin) # x and y coordinates for hexagon cell centers
#hray(xy$x, xy$y,val=stat[,1],lower= stat[,2],upper=stat[,3])
```
