I want to confirm that it worked (took some time though to find the needed
libraries!)
now I get from the readGal the following struct
> str(store)
Formal class 'SpatialGridDataFrame' [package "sp"] with 6 slots
..@ data :'data.frame': 65536 obs. of 1 variable:
.. ..$ band1: int [1:65536] 255 255 255 255 255 255 255 255 255 255 ...
..@ grid :Formal class 'GridTopology' [package "sp"] with 3 slots
.. .. ..@ cellcentre.offset: Named num [1:2] 0 -722925
.. .. .. ..- attr(*, "names")= chr [1:2] "x" "y"
.. .. ..@ cellsize : num [1:2] 2835 2835
.. .. ..@ cells.dim : int [1:2] 256 256
..@ grid.index : int(0)
..@ coords : num [1:2, 1:2] 0 722925 -722925 0
.. ..- attr(*, "dimnames")=List of 2
.. .. ..$ : NULL
.. .. ..$ : chr [1:2] "x" "y"
..@ bbox : num [1:2, 1:2] -1418 -724342 724342 1418
.. ..- attr(*, "dimnames")=List of 2
.. .. ..$ : chr [1:2] "x" "y"
.. .. ..$ : chr [1:2] "min" "max"
..@ proj4string:Formal class 'CRS' [package "sp"] with 1 slots
.. .. ..@ projargs: chr NA
if I understand it right
all the values I want to have should be inside the
store@data$band1
it looks though that my image (one can see it as a matrix with values) now it
gets "converted" to a vector.
How I can keep its matrix "look"
I would like to thank you in advance for your help
B.R
Alex

Subject: Re: [R] REad bitmap files
Try the rgdal package, ?readGDAL will read a bmp file. Building on that and
adding more features is the raster package, see ?raster which will return am
object from reading the file and provide extra support to sort out the plotting
of colour tables etc correctly.
