Dear all,

I have the following rasterbrick (x);

class       : RasterBrick
dimensions  : 112, 272, 30464, 7305  (nrow, ncol, ncell, nlayers)
resolution  : 0.25, 0.25  (x, y)
extent      : -132, -64, 24, 52  (xmin, xmax, ymin, ymax)
coord. ref. : +proj=longlat +datum=WGS84 +ellps=WGS84 +towgs84=0,0,0
data source : /projectnb/climpct/TEX_1986_2005.nc
names       : X1986.01.01, X1986.01.02, X1986.01.03, X1986.01.04,
X1986.01.05, X1986.01.06, X1986.01.07, X1986.01.08, X1986.01.09,
X1986.01.10, X1986.01.11, X1986.01.12, X1986.01.13, X1986.01.14,
X1986.01.15, ...
Date        : 1986-01-01, 2005-12-31 (min, max)
varname     : tex


I can obtain the values by;

as.data.frame(getValues(x))

However, I would like to extract the values by all coordinates in the file
in the form of a dataframe. Is it possible to do so? Any help will be
greatly appreciated. Thank you.

Sincerely,

Milu

Dear Milu,

I think that you are looking for as.data.frame(x, xy = TRUE).

And if you need coordinates as part of your data frame just do
cbind(coordinates(x), as.data.frame(x, xy = TRUE))
