[R] Euclidean Distance in R

1. I have two raster files *.asc (identical size)
2. The data in each contain presence or absence data in each cell
represented by a 1 or 0 respectively
3. I would like to take the location of each 1 (presence cell) in
raster file 1 and measure the euclidean distance to the nearest 1
(presence cell) in raster file 2.
Obviously in some cases there will be overlap so the distance will be zero.
4. I would like the output file to have each individual measurement on
a seperate line in a single file.
I am very new to R, so any help would be appreciated.
