Import multiple tif raster
Dear community
Dear Ivan
Thanks a lot. The code works now. Solution: direct and full path to the .tif files.
I confused back and forward slash
#first import all files in a single folder as a list
rastlist <- list.files(path = "C:/Users/Sibylle St?ckli/Desktop/NCCS_Impacts_Lot2_2022/InVEST/Species_Input/valpar_bee_presence", pattern='.tif$', all.files= T, full.names= T)

Import multiple tif raster
Dear Ivan
Thanks a lot.
I tried now to provide the full path. However probably the "?" in the path produces the error, would that be possible?

paired raster boxplots
Dear Ivan
Dear community
Quite nice book recommendation.
Yes indeed my raster "s" (the shape file for the boxplot classes) has several layers. That's way I tried to select a layer by " s<-sf$Unterregio".

paired raster boxplots
Dear Ivan
Many thanks.
Using my own dataset, my "s" is a layer shape file.
Somewhere I need to define : snew<-s$Unterregio
I tried it to do it before stack(), but it seems to be the wrong way. Do you have any suggestion?
Code:

paired raster boxplots
Dear community
I have two raster files (here r and r2: y-axis) and an equal x-axis (here s,
4 classes).
Instead of plotting two boxplots I would like to plot paired boxplots: for
each class the boxplots from r and r2 paired).
I tried to adapt the code, but I am struggling around with the error:
> names(rs) <- c('r', 's', 'r2')

cups drivers for printing pdf and tif
List,
I updated a gateway/router computer with Centos 5.6 and lost the ability
to print pdf and tif files with the command "lp -d printer img.tif"
This new unit replaced a Fedora 5 system that had been working well, and
is still able to print pdf and tif files withing the same network.
I have other Centos 5.6 gateway's at different facilities that print the
pdf and tif files

Image viewer refuses to print TIF graphics
I'm not sure if it's just the TIFs or if that related at all, since I
have had some luck in printing these before, but recently the image
viewer (eog - the Eye of GNOME, v 2.16.0.1) has responded to a print
command on certain TIFs with nothing. Nothing shows up in the spool
queue for the printer, and, although the printer (a Brother 2140 laser
printer) heats up, it doesn't print

Received fax "offset" in tif file?
Hi, all -- some (but not all) of the faxes I receive on my Sangoma card
have an "offset," where the right 3/4 of the fax are shifted left, and the
remaining portion is "pasted" on to the right edge; see
jots.org/~ken/fax.jpg for an example.
Anyone have any ideas on how to get this working? Since I'm using a
Sangoma T1 card, I tried out using ztdummy as a timing source (as

FFA (Fax For Asterisk) tif file (size) problem
Hello,
We succeed to send faxes using FFA, when the files are converted to tif
from PDF using gs, but it doesn't work with tif files we copy/upload
directly from our PCs.
We saw in the manual that the size is important, since we got the error
"FAX handle 0: failed to queue document 'filename.tif'", so we set it to
1680x2285, but it's still rejected.
Is there a way

Tif image to 8bit colour matrix.
Dear listers,
I have a collection of tif images that I would like to convert, in R, to a
matrix containing the values of the 8bit colour. Ideally, I would like a matrix
for each of the colour channels (red, blue and green). I have 'googled' and
searched the help list but have yet to find a solution and hope that someone can
point me in the right direction.

[OT] Using GS to create .tif files
I've managed to use GhoustScript (gs) to take a postscript file and
convert it to tiffg3, but I CANNOT seem to make it merge multiple
files. Here is the output from tiffinfo on the file that SG generates:

[Rdev] any way to generate "bitmap" (tif, jpeg, png etc) files in R CMD BATCH
Hi Community,
here is the problem, Linux problem (reported to work on Windows). I need
to generate graphical output in any of bitmap format under the 'R CMD

session, such things as X11, png and jpeg are not usable in BATCH (they
cannot be switched on by --gui-X11 etc) and X11 is prompted to be
required for png. At

Extracting xy from raster based on raster value
I have a raster (which I called glc), which I read
into R as a raster with "raster.create.from.file" from the raster package (R-forge). Values in glc range between 1 and 27 (whole numbers only). I'd like to extract all cells with a value of 1 to create
a new raster with only the cells that have a value of 1, or to extract
the xy values of all raster cells with a value of 1. Could you

How write raster files after manipulation?
I have 12 binary (raster) files
https://echange-fichiers.inra.fr/get?k=k3M2jatJyHy65Cs99G4 .
I would like to calculate the moving average for the 12 values for each
pixel in the 12 files.
For a simple vector we can get a moving average by using this :
x <- c(1,2,3,NA,NA,4,6,5,6,4,2,5)
movingmean <- rollapply(x, 3, FUN = mean, na.rm = T)
