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)
Since I am sending a graph, I am trying to save it using tiff.
Here is the code I am using:
tiff(filename = "c:\\aaa.tiff",
res = 800, pointsize = 2)
?tiff
(Merely from reading the help pages... not claiming to be an expert in
graphics devices.) At the moment I suspect you are running into
problems because the default units for the height and width of the
tiff device is in pixels (="px") and the default size for each is 480.
The width in pixels is less than 800 so you need to get your 800 into
480 by dividing by 2. Perhaps changing the units to "cm" or "in" and
then the using materially smaller sizes for height and width you can
get more satisfactory combinations of size and resolution.
(Of course, this does not apply to EPS since it is not a raster image
format. Either your publisher is confused on this point or you haven't
faithfully transmitted their message.)

plot(1:100)
dev.off()
But sadly, it produces a very "bulky" image (and if I where to not use
pointsize = 2, I would get the error massage:
Error in plot.new() : figure margins too large
)
I am clearly missing something basic here about the use of DPI, I
would
appreciate any help in figuring this out.
Thanks!
