Robert,
Thank you very much for the help - it works.
Also, thanks for adding this function to your package - it will certainly be
very useful.
Regards,
Thiago.

Hi, I want to read an existing geotiff file (with georeferencing info),
operate on the raster data, and write out the result to a Float32 file. I'm
working with hyperion data which is Integer.
This code creates an outputfile, however, the output file t1.tif is Integer.
I need it to be float.
fn
You can use readGDAL and writeGDAL. If you really need lower level gdal
functions you can look at the code of these functions. you can also use
functions from 'raster':
library(raster)
r <- raster(fname)
x <- r * 2
x <- writeRaster( x, "t1.tif")
plot(x)

Hi,
Trying to make a SpatialPoints(obj) and encounter the following:
> out_dest_sp <- SpatialPoints(out_dest, proj4string=proj)
Error in validityMethod(as(object, superClass)) :
Geographical CRS given to non-conformant data: -173.07856

Hi Robert,
Just wanted to report back on the solution you gave me, which worked
perfectly as you wrote it.

Greetings,
I'm sorry if this question is too basic, but I just recently moved to R.
Let's say I have:
lon <- c(-115.86, -115.83, NA, -115.78, -115.78, -115.75, NA, -115.68,
-115.66)
lat <- c( 29.76, 29.61, NA, 29.55, 29.53, 29.41, NA, 29.13,
29.09)
and I need a new set of coordin
