Good Morning. Below I like statement like j<-grep(".r\\b",colnames(mydata),value=TRUE); j with the \\b option which I read long time ago which Ive found useful. Are there more or these options, other than ? grep? Thanks. dstat is just my own descriptive routine. > x ?[1] "age"????????? "sleep"??????? "primary"????? "middle" ?[5]

Hi there. I am still trying to get the RSVGTipsDevice to work, yet I can not. I have copied the first example from RSVGTipsDevice documentation: library(RSVGTipsDevice) devSVGTips("C:\\svgplot1.svg", toolTipMode=1, title="SVG example plot 1: shapes and points, tooltips are title + 1 line") plot(c(0,10),c(0,10), type="n", xlab="x", ylab="y",

Dear R community members, I think I am asking a very simple question, but I really looked up in the faqs and manuals and found nothing helpful. I am trying to plot a data frame with the following structure (this is just a small extract): glo conc odor line series X1 X2 X3 X4 X5 X6 X7 X8 X9 X10 X11 X12 X13 1 0 AIR LN1 UP -0.488

Hi there. I have a matrix that provides place names and the distances between them: Chelt Exeter London Birm Chelt 0 118 96 50 Exeter 118 0 118 163 London 96 118 0 118 Birm 50 163 118 0 After performing multidimensional scaling I get the following points plotted as follows

Basically, I?m trying to install rJava on my windows XP machine. I think I have succeeded in doing so as it appears in the list when i type library() in R. However, when i type ?library(rJava)?

Hi there. I have the following graph: http://www.nabble.com/file/p10928148/map.jpg However, some datapoints occur at the same place as other datapoints and are so layered on top of each other. I would like to know if there is any possible way in which I could view those datapoints that are layered on top of each other ...maybe by rotating using latitude to show the datapoints underneath (but

Hello there. When I try to start the jvm using .jinit() after loading library(rJava) I don't seem to be able to as I get the message: Error in .jinit() : Cannot create Java Virtual Machine What is going on here?

Hi there. I am trying to install SJava on my windows xp machine. I downloaded the windows source file SJava_0.69-0.tar.gz from the web site http://www.omegahat.org/RSJava/ I have folloed the XP command line instructions as directed in the table underneath the download link: cd $RHOME/src/library unzip SJava_0.69-0.zip cd SJava ./configure.win $RHOME cd $RHOME/src/gnuwin32 make pkg-SJava I

Hi. I know matrices that use distances between places works fine when using cmdscale. However, what about matricies such as: A B C D E A 0 1 23 12 9 B 1 0 10 12 3 C 23 10 0 23 4 D 12 12 23 0 21 E 9 3 4 21 0 i.e. matrices which do not represent physical distances between places (as they would not make sense for real distances such as the one above)

Hi all, I'm seeing this failure on my PPC G4 box running TOT with llvm-gcc 4.2. Is anyone else seeing this? I'm sure it's related to the byval stuff that's recently gone into LLVM. I'm attaching the output of this command: $ llvm-gcc -emit-llvm -O3 -S -o - -emit-llvm /Users/wendling/llvm/ llvm.src/test/CFrontend/2008-01-25-ByValReadNone.c As you can see in it, there

Hi, I've spent a while scrabbling around at this problem, to no avail. I'm sure there /should/ be a simple answer... I have a large (14 million rows) data set, with two columns. Each row contains the number of times an individual moved, and the distance that individual moved in total. I would like a figure where the colour indicates the density of points, rather like this one my

R experts, I have three columns. c1 and c2 are numeric variables whereas c3 are the clusters classes (nominal variable, 10 different: cluster1, cluster2, cluster3, cluster4, cluster5 ....). I'd like to plot c1 against c2 (easy!) in a 2D plot and put different color depending to the cluster class automatically regardless the number of clusters. Could anyone give a hand?

Hello, i'm a french student of medical oncology and i'm working on breast cancer. I have a variable with the histologic type of tumor wich is between 1 and 5. I use as.factor function to make some variable with level between 1 and 5. When i put it in the cox model i have only the level between 2 and 5. The level 1 doesn't appear. I think i have to change the number of level but i

Hello, I’m trying to follow the syntax of a script from a journal website. In order to create a regression formula used later in the script, the regression matrix must have column names “X1”, “X2”, etc. I have tried to assign these column names to my matrix ScoutRSM.mat using a for loop, but I don’t know how to interpret the error message. Suggestions? Thanks, Paul
