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 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 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 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

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

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.

Hello everyone, Thanks to the people who so kindly responded to my earlier query about how to get R to retrieve my previous command when I hit the up-arrow key. Several people pointed out to me that in order to enable this feature I need to re-install R with the GNU readline library. My question now is: how do I accomplish this? Can anyone tell me what changes I need to make to the

Dear list, I have problems installing R-2.0.1 on SUSE Linux 9.2. I used the following commands in order install R in /usr/local ./configure --with x11 --with-readline make make install When starting R and trying to display a plot on the X-window system output is written to a postscript file. When I try to run x11 with >x11() Error in X11(): X11 is not available. I do have a running

Does anybody know a way to edit your command line arguments on the command line, other than deleting everything and re-typing? My user just want to be able to use emacs like commands - like you can do in a shell, and s-plus from what he says. I attempted to set up the emacs add-on, without much success, on a Solaris 7 box, but he doesn't really want that, he just wants the command line

Hi all, I have got 27 graphs to export (not a lot...I know!). How can I fit all of them into a single file like PNG without adjusting the size of the graphs? What's in my mind is like pasting graphs into Word, in which I can just scroll down to view the graphs. Thanks for your attention. Much appreciated. Chris -- View this message in context:

Pretty soon, hopefully, the RAqua version will make the Darwin/X11 version unnecessary. In the meantime, for convergence, I'll modify the Gifi version in various ways. -- It's 1.7.1 -- It no longer supports gnome -- It still uses Tcl/Tk for X11 (using 8.5 from CVS) !! It no longer uses anything from fink (readline and dlcompat as on Stefano's site, jpeg and png and teTeX from

Hi, I wish build a R-script (or a R-function) that read a number from the keyboard and then process it. For example: from R I load the function X, that ask me the level of confidence "\alpha", by keyboard I write 5 and the function go on. Thanks in advance Paolo [[alternative HTML version deleted]]

Hello How to create plots dynamically with results of several analysis ? I got many outputs from lm fuction like: mp1.lm mp2.lm mp3.lm mp4.lm mp5.lm ... I'd like to make experimental versus predicted response plots of all analysis in a 'for loop': for( i in 1:10){ x11() plot( mp*i*$experimental_response, fitted( mp*i* ) ); abline(0,1) } I tried: paste( 'mp', i,

Help! Weird behavioral difference between R interactive and command-line? Hi all, This weird problem has been bugging me for a while. If I run the R program in an interactive session, it worked; But if I run the R program on command-line, it stopped with no reason: with "Execution halted" message and without any specific error messages. What could be the problem? Thanks a lot!

Hello, I am using setwd() to change the working directory but I have to enter it everytime I open R, is there a way to set this permanently as a working directory?

Some years ago, if I recall correctly, I learned of a package that included a function that would write a plot to a file so that one could associate hyperlinks with elements of the plot, such as points. Then, when the plot was displayed in a browser, one could click on (for example) a point, and jump to wherever the hypelink pointed. I don't remember then name of the package or function,

You are right that there are no NAs in the practice data. But there are NAs in the moving average data. To see this, break your work into two separate steps, like this: tnr.ma <- ma(dat3[1:28], order=3) TNR_moving_average <- forecast(tnr.ma, h=8) I think you will find that the warning comes from the second step. Print tnr.ma and you will see some NAs. -Don -- Don MacQueen Lawrence

Is there a package or a command that does window aggregation like select sum(col1) over (partition by col2, col3 order by col4 rows between unbounded preceding and current row) as sum1 from table1 ; the above is Netezza syntax, but Postgre has same capability.

Hello I am trying to input some co-ordinate sets into R of the form x,y by using lists. The command I am using is: p1 <- list(x=c(3445,563,646), y=c(234,567,456)) However the actual co-ordinate sets that I am trying to input have 305 points each and I think that the program will not accept a command that is as long as necessary. Is this so? If this is the case can you tell me how to read
