Hi R User,
I am wondering how I can extract the value and want to see the value in table. Is there way?

suppose I do have image  (raster package)

r
class       : RasterLayer
dimensions  : 192, 186, 35712  (nrow, ncol, ncell)
resolution  : 0.5, 0.5  (x, y)
extent      : -125, -32, -56, 40  (xmin, xmax, ymin, ymax)
coord. ref. : +proj=longlat +datum=WGS84 +ellps=WGS84 +towgs84=0,0,0
data source : in memory
names       : layer
values      : 3.523291e-09, 0.96676  (min, max)

I want to see these values in column. if possible, also want to see XY as well as.
it must be busy, but I could not figure it out.

thanks
