Hello there,
I'd like to read several raster (all same size and resolution) into R
using the suggested command
stats <- readRAST6(c("LRM_smoothed", "Band74_scaled", "coombe_ground",
"intensity_smoothed"), cat =c(TRUE,FALSE), ignore.stderr = TRUE)
I get the error:
Error in readRAST6(c("LRM_smoothed", "Band74_scaled", "coombe_ground",
"intensity_smoothed"), : vname and cat not same length
vname <- c("LRM_smoothed", "Band74_scaled", "coombe_ground",
"intensity_smoothed")
cat <- c(TRUE, FALSE)
length(vname)
length(cat)
How is the function supposed to guess which of the four layers is
categorical? Are any of them categorical?
Unfortunately I don't understand what the error message is trying to
tell me - any help deciphering this error would be gratefully
appreciated.
Also where can I find more detail on the readRAST command to work out
this error message for myself? I have looked in the sp.pdf and online
for documentation but can't find anything but maybe there's another
resource I don't know of yet?
?readRAST6 or help(readRAST6)
Do you have a library - you haven't given any affiliation yet? ymail.com
isn't informative. Look for Neteler & Mitasova 2008, the GRASS book,
and/or Bivand, Pebesma & Gomez-Rubio 2008, the R-spatial book.

Thanks for reading,
