similar to: Exporting Numerous Graphs

Hi all, I have imported a value 3:00 from Excel into R using read.csv. I want R to recognise it as 3:00am (time data). How do I do it?

Hi all, I have a dataset similar to the following Name Date Value A 1/01/2000 4 A 2/01/2000 4 A 3/01/2000 5 A 4/01/2000 4 A 5/01/2000 1 B 6/01/2000 2 B 7/01/2000 1 B 8/01/2000 1 I would like R to remove duplicates based on column 1 and 3 only. In addition, I would like R to remove duplicates based on the underlying and overlying row only. For example, for A, I would like to remove row 2 only

Hi everyone, I have written a script which exports my graphs as a PDF file using the function pdf(). For instance, I run the script and it exports a PDF called "version 1". Then, I have got a new dataset and want to run the script again. What it usually does is overwriting "version 1". But I want it to check if "version 1" already exists. If so, then I want the new

Hi all, I have a dataset which consists of 2 columns. I'd like to plot them on a x-y scatter plot and fit an exponential trendline. I'd like R to determine the equation for the trendline and display it on the graph. Since I am new to R (and statistics), any advice on how to achieve this will be greatly appreciated. Many thanks, Chris -- View this message in context:

Hi all, I have got a dataset like the following: a b c 1 5 2 3 7 I am taking the minimum of each column and use it as the minimum of the y-axis of my graphs. My scripts (simplified version) are like the following: f<-array f[1]=a f[2]=b f[3]=c for i in 1:3 name=f[i] ymin<-min(dataset$f[i]) plot(x,y,ylim=c(ymin,100)) The script stops at b, because the min function returns inf

Hi all, I have written a note near each of my graphs using mtext. mtext(text,side=1,line=4,cex=0.5,adj=0) Then I have exported the graphs as a PDF file. pdf(file=name,paper='a4',width=7.27,height=10.69) The mtext appears OK in R. But it looks like it is bolded in the PDF file. http://n4.nabble.com/file/n2016971/graph.png I am not sure if this is actually my monitor/computer's

Hi all, I am new to R and I have got a question in regards to factors. Say I have a simple dataset like the following: Name Time Value a 1:00 1.25 a 2:00 1.26 b 1:00 1.29 b 2:00 1.28 c 1:00 1.21 c 1:30 1.20 c 2:00 1.23 I want to write a script that automatically plot value against time for a, b and c.

There are a couple of points to keep in mind when doing a log-transform of an exponential model, such as -- y = a*exp(b*x) 1. The implicit statistical model is multiplicative in the error. The implied statistical model of the log transform is -- log(y) = log(a) + b*x + u which implies -- y = a*exp(b*x)*exp(u) A linear regression in the log

I would like to learn how to parse a mixed text/xml document I downloaded from the sec.gov website (see example below). I would like to parse this to get the value for each xml tag and then access it within R, but I don't know much about xml so I don't even know where to start debugging the errors I am getting in this example code. Can anyone help me get started? Thanks, Roger ftp

HI: I have tried to find a way in which to export/save graphs via the command line. I know i can right click on it and save it as wmf etc. But I was wandering if there is a function such as Splus' export.graph Thanks >From Alberto Nettel's Desk University of Calgary Math & Stats Department.

Hello all, I am fairly new to R and hope not to be a bother. I have used the R-GUI a small amount under Microsoft Windows0S. I recall the ability to export created charts and graphs to JPEG or other various image formats. How can I do this in the UNIX CLI version? Thank you. Also, I have receiveder the following error after installing a package via CRAN. How would I fix this? Thank you. Jess

I have trying to figure this out all day so hopefully the answer isn't too obvious. I am able to view a graph in the viewer window. However, I need to export graph outside of the viewer window. Here is the script I am using: > png("Compare.png") > plot(compare$DepthSLI, compare$DischargeSLI, col="blue", xlab = "Average Water Depth (cm)", ylab =

Hi guys, Yesterday I posted my first couple of questions (see bottom of this message) to this forum and I would like to thank you guys for all the useful feedback I got. I just would like to make some comments: 1. Exporting R graphs as vector graphics: The best answer came from Thomas Lumley <tlumley at u.washington.edu> He suggested using the RSvgDevice package. As far as I know SVG

Hi, I have been a happy user of R for windows for more than a year, however, recently, I started using linux as my operating system and now I have practically switched completely. Of course, I still use R with linux, however, certain nice features of R in windows seem to be missing or hidden. I need help in basically two points: 1. In windows, I could copy the contents of a window graphic's

I'm constructing a raid 5 of 3 160gb sata drives. They're connected to a promise sx4 150 card, using the kernel drives (not promise's binary only drivers). the raid builds fine, as does creation of the ext3 filesystem. however, if i then run e2fsck (with the -f option since the filesystem is brand new) i get thousands of these type of errors: Inode 15461 has imagic flag set.

After upgrading to 3.0.26a and moving to linux my member server gets hundreds of IPC$ connections when I run smbstatus. I also see in my logs the following...

Dear list members, I am facing some problems using the aggregate() function. I want to calculate a sum and a mean of one variable over the combination of 12 factors with the aggregate() function to avoid loops but it doesn't work (or the job is far too long, it exceeds 2 hours). It works with a fewer number of factors, so I constructed a factor being the levels combination of 7 factors (I

Dear R Users, I'm trying to use the reshape package to 'melt' my gridded data into column format. I've done this before on individual files, but this time I'm trying to do it on a directory of files (with variable file names) - therefore I have to also use the 'assign' command. I have come up against a couple of problems however and am therefore seeking advice... >
