segfault when running heatmap()
Hi, I was wondering if someone in the mailing list has any insight into this
segfault error that I consistently find when running a script containing
heatmap() in R 2.8.1 and 2.8.0 on a Linux 64-bit machine.
Some points:
1. This occurs when running heatmap().
2. Interestingly, if I source() the script or copy and paste the script in
its entirety, this error occurs. However, if I run the

X11cairo with antialias="none" buggy under MacOS?
using
X11(antialias="none")
plot(1:10)
produces an incomplete plot with 2.7.0. under
MacOS 10.4.11: both y-axes are missing.the
y-ticks (except the tick at `2' wich is missing)
including labels are there.
this happens with a 1280x854 labtop monitor.
is this known behaviour/a cairo bug?

tiff() woes
Hello all,
a friend has a problem with tiff() which I was unable to help about. I
searched the error messages to no avail. When he tries:

5, units = "cm", bg = "white", res = 1200)

Preparing high quality figures with tiff as end result
Hi all,
I'm currently preparing some figures that will be submitted to PloS One.
In their guidelines they state that they will only accept figures in
tiff or eps format, with the warning that eps figures will be
converted to tiff format ( see
http://www.plosone.org/static/figureGuidelines.action ).
Because of this conversion, I figured I'd generate tiff-format figures
from the beginning.

problem with lattice tiff or bitmap: character size and color
Hi all,
I am trying to make tiff files of lattice plots at a resolution greater
than 300 dpi required by a journal (PLoS ONE). I have tried both the tiff
and bitmap functions. tiff keeps panel colors but reduces axes and tick
labels so they are nearly invisible. bitmap maintains correct label size
but only produces greyscale. Regular plots work fine with tiff; the
problem is only with lattice

tiff(), jpeg(), and png() in R 2.7.0: problems if 'units = "in"' but default height and width
I love the new tiff(), jpeg(), and png() in R 2.7.0 but found
an issue that I didn't see reported.
When specifying 'units = "in"' but forgetting to change the
default height and width (so the figure is unintentionally
going to be 480 inches by 480 inches) I run into problems.
Here's the reproducible example:
tiff("a.tiff", units = "in", res = 1200,

Is libtiff >= 4.0.0 now required by R for TIFF support?
We recently discovered that since R 3.3.0, on our CentOS 6 based
cluster, R gets built without TIFF support. The last version where TIFF
support was built, was 3.2.5.
We have libtiff 3.9.4 installed:
$ rpm -q libtiff-devel
libtiff-devel-3.9.4-21.el6_8.x86_64
(Since CentOS 6 is so old, we have manually installed newer versions of
some dependencies: curl 7.46.0, zlib 1.2.8, bzip2 1.0.6, xz 5.2.2

Height not set properly in grDevices::jpeg() with type = "cairo"
Hi,
I have been having issues producing plots in JPEG format, using type =
"cairo" to get better anti-aliasing. When trying to set the physical
size with units = "cm" or units = "mm", the width is set correctly but
the height is not - it looks like the height is simply treated as
pixels regardless of the 'units' argument.
Example:
x = 1:10
y = 2 * x

tiff printer driver in wine?!
Hi, we need a solution for running a tiff printer driver
within wine which creates tiff files from a word document,
for example.
Only printing through cups and/or lpr to a postscript file
is doing now as known, but this is much overhead for the
application we want to run. There should be a way to run
such a tiff printer driver in wine.
Or is doing anyone writing wineps like tiff driver

Wrote new tiff package, would like big-endian tiffs for testing
Over the years I have noted a couple of people interested in an R package that will read tiff files. There were some valid arguments against (e.g. R is not an image editting suite, libtiff does not support all tiff files, etc.). True enough, when I want to work with family photos, I use Gimp. But in my research I use tiffs as data sets in the context of computational biology and molecular

Saving multiple 3x3 TIFF graphics inside a loop

12-bit functionality in tiff package
Hi,
We have recently been using the tiff package for reading tiff images into the Bioconductor Package EBImage. This has been extremely helpful in conjunction with other steps to eliminate dependencies on ImageMagick.
However, it seems that 12-bit images are not supported. We were wondering if there are plans to extend the functionality of the readTIFF() function in the tiff package to

The best way to end up with TIFF {Was: end up with WMF)
Hi all
I posted a couple of days ago about how to end up with wmf files
eventually in R for linux.
The short answer was: you (probably) can't...and don't!
The journal in question also accepts TIFF files, I am told (it's
a physiology journal).
So I adjust my question: What is the best way to get TIFF files
out of R? It can't create them directly as far as I can tell.

Saving plot to tiff, with high resolution for publication ?
Hello all.
A Journal we are sending an article to is asking for the following:
To ensure the best reproduction quality of your figures we would appreciate
high resolution files. All figures should preferably be in TIFF or EPS
format... and should have the following resolution: Graph: 800 - 1200 DPI
Photo: 400 - 800 DPI
Color (only CMYK): 300 - 400 DPI (DPI = dots per inch)

Creating tiff with 1200 dpi
Hi all,
I am trying to create images in R suitable for journal publication. I'd
like to make an image that is 3.6" wide and 5.08" length, and 1200 dpi.
When I create a tiff file that is 800 dpi and 4x4", it works (although
doesn't look good).
But when I create a tiff that is the size and dpi I want, it doesn't
work. I get the following error:

display SVG, PNG, GIF, JPEG, TIFF, PPM in new plot frame
Dear R-help
I want to display an image file in a new plot frame.
SVG is my preferred format, but I can also consider
PNG, GIF, JPEG, TIFF, and PPM (from ImageMagick).
By way of background (although not material to this
posting), the image file is generated by a call to
'dot' (part of the 'Graphviz' suite) after the required
.dot file has been produced using hand-crafted R code.

Raster images and saving with original pixel dimensions in tiff, jpeg, or png perferablly.
Hello R-Help,
I want to be able to read in a raster image, plot it with grid.raster
or rasterImage and save the image with one pixel per a pixel element
from my array. Saved preferably in a common image format.
The real goal of my question is to eventually read in images with text
on them, manipulate them with my controlled functions, save them
without changing the image dimensions, and perform
