I am using R 2.4.1 with Windows XP. I use the plot command in a fairly simple script and I use the right mouse click on the plot and save as a postscript file. I used the resultant file in a paper which was submitted electronically. However, I get the following response from the journal: Your manuscript has been unsubmitted because you failed to meet the submission guidelines as indicated

I've used to have a script with a barplot command it in, preceded by a png: png(graph.file,height=H,width=W) barplot(t,names.arg=breaks[2:(length(t)+1)],tck=gridlines) -- worked before R 2.6.2. When I tried it in R 2.6.2, which I have for a while but didn't run with that script, it complained, the margins too large, and I've googled the messages from our list where neither

Hi, I am new to this mailing list. Didn`t find the answer in the archives. But I guess, there are people out there, who know the solution: In an automatic script, I want to produce simple plots. First I prefer pdf, because of scalability and standardization. But when I have too many datapoints (say 300.000) the viewing and printing is very, very slow. So I decided to take some bitmapped format

Dear all, In grDevices R functions cairo_pdf and cairo_ps it is mentioned that when transparency (alpha channels) are used in vector output, it will rasterize the PDF or postscript exported graph at a resolution of 72 dpi : https://stat.ethz.ch/R-manual/R-devel/library/grDevices/html/cairo.html You can see the problem if you try library(ggplot2) cairo_ps(file = "test.eps",onefile =

The result I'm aiming to achieve is a bitmap that can be imported into a PowerPoint file that shows what's behind the lines of the plot. There's a way in PowerPoint that almost works. By choosing a colour to set as transparent, what is behind the graphic is indeed visible, but it's at the expense of losing line and text definition. I notice there have been discussions about

Hi R Users, I'm using following sample code to save png plots. png(file="sample.png", width=8, height=6) Then I copy or use "insert pictures" function to get the image into MS Word. After copying, if I try to stretch or re-size the image it starts getting distorted. Is there a way to standardized graph pixels so that the sharpness of the graph is maintained (at least for

Hi, I am trying to infer the dimension of an opened bitmap (png, jpeg, bitmap device...) from par() parmeters. From the help on par(), I found that: > dim <- c(400, 200) > png("foo.png", width=dim[1], height=dim[2]) > dim2 <- par("din") * par("cra") / par("cin") > dev.off() > dim2 [1] 399.9999 199.9999 I've tried the above on

Hi, I try to create PNG images of a certain size where each pixel intensity corresponds to exactly one probe signal in an Affymetrix array. I try to use png() and image() with zero margins to do this. Example: z <- matrix(1:15, nrow=45, ncol=30) png("large.png", height=nrow(z), width=ncol(z), bg="red") par(mar=c(0,0,0,0)) image(z, col=gray.colors(16), axes=FALSE)

I have to create a plot with a print density of 600 dpi . Within R, is there a way to determine the print density of a plot? Any assistance is much appreciated, regards Bob

Has anyone successfully created a PNG file for a dendrogram? I am able to successfully launch and view a dendrogram in Quartz. However, the dendrogram is quite large (too large to read on a computer screen), so I am trying to save it to a file (1000x4000 pixels) for viewing in other apps. However, whenever I try to initiate a PNG device, I get a "need finitite 'xlim' values"

Dear Rusers, My manuscript has been conditionally accepted recently. The problem to generate the high resolution figures in R for the manuscript cannot be solved by me. The journal editor ask me to generate the figures with a minimum resolution of 500 dpi. I have tried the *menu-driven method* to save the figures as JPEG (100% printed quality), but the results seem not to be very good. I have

If I put only one plot in a png, I can drag the generated png on the edges and it changes its size by this. But when I put several plots on the same sheet using mfrow, the size can no longer be changed when viewing the file, and the resolution is bad. What do I need to do to keep the variability of size in a multiple figure environment?

Hi, I want to save a plot in the windows device as png and the default resolution is 72dpi. Is it possible to increase the default resolution to for example 300 dpi? I have thought of using function png(..., res=300), but the problem is that the figure produced this way looks different than the one shown in the windows device. One notable difference is the missing of some ticks in the x

I'm trying to use R in a cgi script to produce graphics files in png format, and I'm having a problem. My shell command line looks like this: R </usr/dfs/auction/eligibility.R --no-save >/tmp/R.out and the line in the R script looks like this: png ("foo.png", pointsize=18) If I run outside the cgi context, it runs great. When run as in a cgi script, I get this error

Hi, I have a run of 5 graphs that I want to place them under the same page. Everything works fine to place them in a pdf file , or eps file, but when it comes to have a high quality of 300 dpi these graphs are not good. For example I open the eps file with Adobe Illustrator (AI) and it shows that it is a 72dpi graph. If I start with a 72dpi graph AI cannot improve this to 300 dpi. Q: HOW CAN A

I can use a postscript device to produce a file which I can open with the Gimp, then save quite a good png file. If I try to use the png() function directly, I get something rather like a graphics screen dump. The help file doesn't tell me whether it should be like that or not. _ platform i686-pc-linux-gnu arch i686 os linux-gnu system

Dear R list, I do encounter the following problem by generating either a png-file (example below) or a jpeg-file: By employing 'box(which="outer")' a box is drawn, except for the right line. If I generate the plot without the 'box(which="outer")', a line at the bottom in the graphics file still appears. However, both plots are displayed correctly in the R

Hi Has anyone had success with setting image resolution with Rmagick. I am resizing an uploaded image with Rmagick, problem is it keeps the original images resolution and I want to change it to 72dpi. <<<<<< code example >>>>>>>>>> # these are the various techniques I have tried when and after reading the file, trying any or all of them does

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: fteTYGeh2v.tif: TIFF Directory at offset 0x8 Subfile Type: multi-page document (2 = 0x2) Image Width: 1728 Image Length: 1056 Resolution: 204, 96 pixels/inch Bits/Sample: 1
