I have two data frames which has 3 columns each.My first data frame is large like this below "new.col ppm.p. freq.p." "1_3_diaminopropane 3.13859 5.67516" "1_3_diaminopropane 3.137 6.65388" "1_3_diaminopropane 3.13541 8.0142" "1_3_diaminopropane 3.13383 9.64184" "1_3_diaminopropane 3.12075 298.243" "1_3_diaminopropane 3.1152

I have hundreds of text files which has data like a data frame with three columns.The column names are same in all the files.I need to merge all files into a single big file.

I was trying to install software named ncview on a centos 5.3 box. ./configure command gave this error: Error, the X libraries and development headers must be installed for ncview to work! I was surprised that there were many google hits related to ubuntu, none for centos. So even though I eventually figured out what to do, I decided to share this with the list anyhow, so maybe next time I

I would like to to know about conversion from jpg file to lss format. I used ppmtolss16. It is giving following errors. for .jpg file: ppmtolss16: stdin is not a raw PPM file at ppmtolss16 line 105, <STDIN> line 1. for .png files: ppmtolss16: stdin is not a raw PPM file at ppmtolss16 line 105, <STDIN> line 1. from .ppm file: ( I converted .jpg file in to .ppm file using irfanview)

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.

I'm trying to (re)learn Sweave and run into some problems. I use now ubuntu (8.10), emacs + ess. Slowly getting upto speed on ess.

Hello, I want to make a program to extract frame from a theora movie as images. I tried with the decoding example located at theora web site (dump_video.c. I use it to extract a frame as yuv image but when I try to convert it to ppm with yuvtoppm program i obtain a strange image ( see http://poux.be/tmp/file.ppm ). I think it's a problem with the byte order for yuv, but don't I don't

Upon finding a different image conversion program, I have eliminated the Premature EOF problem that I had(apologies if I post this before the moderator approves my first post...you can ignore it if/when it shows up). Now, I am seeing the script complete with no error. I tested my syslinux.dpy file with the syslogo.lss file from the samples, and it's fine. The lss file I created, however,

Hi all, I'm trying to work out the following problem, but I can't imagine how.

Dear all, Several days ago, I posted How to write a bmp file pixel by pixel. Instead of bmp, I succeeded in writing a PPM file by using the pixmap package. Thanks for the hint generously provided by Uwe Ligges. Now I have a new question. How to convert a PPM file to BMP file in R? I know I can do this in photoshop or by some other softwares, but I think if I Can do this in R, that

I have a graph plotted in r.The x axis tickmarks are at 0,5,10. I need a graph with resolution of tickmarks at 0.1 interval.When i place tickmarks of 0.1 intervals using the following command axis(1, at=seq(0,5,0.1), cex.axis=0.7, las=2) I only get the tickmarks of 0.1 interval that are very closed placed in the graph.I need to increase the spacing between each tickmark. Please anyone help out

Is there a tool for reading a graphics file into an object? I might not be looking with the correct vocabulary, but I'm finding lots of references to producing graphics from R, but not any for inputting graphics into R. I'd like to use a jpeg image and have the data available in R for analysis. I could convert the image to another format, PPM perhaps, and parse that in, GRASS seems like

Running v5 64bit on a Dell 1950. A cluster of 3 DB machines, identical hardware. One of them suddenly became slower 2 weeks ago. tar -zxf with a large file on this machine takes 1.5 minutes, but takes only 10 seconds on any of its siblings. CPU usage seems high while untarring, with lots of user and sys cycles being used, but almost no wait cycles. It doesn't matter whether I untar on a

Dear R help list members, I am experiencing difficulty in trying to generate a subscript '2' in an axis label. Although I can get the '2' into a subscript using expression(), R then forces me to leave at least one space between the '2' and the following character. My label is supposed to read 'N2O concentration (ppm)', and the space between the '2' and

hi, one pretty small question .... i wanted to create my own mini-distribution, using syslinux to boot the system. Everything works pretty fine, but now i wanted to see a graphic on boot time. :-) I saw i have to create a graphic with the file-extension .ppm ... but please tell me with which programm i am able to use such an extension? gimp? dont think so ... hope to hear of you ... thanks in

Hi, I'm using R 2.5.1 and gstat 0.9-39 library and I'm working with the jura data set provided by gstat library. I tried to plot a graph of metal concentrations (let's say Cd) with the command spplot, but I realized that the default lags are equally distributed between Min and Max. I did: library(gstat) data(jura) jura.pred.xy <- jura.pred names(jura.pred.xy)[1:2] <-
