Dear Rusers, I want to know which function in R can perform the following tasks: 1.surface-data grid(x,y,z) #which could be done in splus, the name was from splus's options of graph 2. contourplot(x,y,z) #which could be done in splus By the way, where can i find some useful materials to learn to plot 3-dimensionel graphs? Thanks! -- With Kind Regards, oooO::::::::: (..):::::::::

Hi, there I'm trying to get the value of the Mean Square from the ANOVA model summary that comes from specifying the error term, and am wondering if one can actually do this ( I know it's possible when using anova(lm) objects and the like, but I'm having a tough time with it under this framework). There does appear to be some indexing in the output of this type, but perhaps not

Hi, how can i plot two different x axis in a ggplot2 qplot? I want to plot Farenheit and Celsius in one diagram. x1:Farenheit x2:Celsius kind regards, -- Jonas Stein <news at jonasstein.de>

Hello all, How to draw a line in plot when I know the start point(x1,y1) and end point(x2,y2)? I need make this as additional information in the graph: plot(wl2[[1]],wl2[[2]]) I think that is possible make this with the function abline(), is possible? I looked the function lines() too, but don't understand as make. Thanks! Lesandro Veja quais são os assuntos do momento no Yahoo!

Hello, I'm trying to do cor(x1,x2) and I get the following error: Error in cor.default(x1, x2) : missing observations in cov/cor A few things: 1. I've used cor() many times and have never encountered this error. 2. length(x1) = length(x2) 3. is.numeric(x1) = is.numeric(x2) = TRUE 4. which(is.na(x1)) = which(is.na(x2)) = integer(0) {the same goes for is.nan()} 5. I also try

Hello R-helpers, Please see a self-contained example below, in which I attempt to plot the effect of x1 on y, while controlling for x2. Is there a function that does the same thing, without having to specify that x2 should be held at its mean value? It works fine for this simple example, but might be cumbersome if the model was more complex (e.g., lots of x variables, and/or interactions). Many

Dear All, I have a data frame with n columns: X1, X2, ., Xn. Now I want to create a new column: if X1 = X2 = . = Xn, the value is 1; Otherwise, the value is 0. How to do that in a quick way instead of doing (n choose 2) comparisons? Thank you, Frank [[alternative HTML version deleted]]

Hello, I am not sure what to write in the subject line, but I would like to take a character string that is a variable in a data frame and apply a function that takes a numeric argument to this character string. Here is a simplified example that would solve my problem. Imagine I have my data stored in a data frame. > x1 <- x2 <- x3 <- x4 <- x5 <- rnorm(20,0,1); > data <-

Hi, I recently started to use Endnote under wine (0.9.57 with Ubuntu 7.10). So far it runs without major problems, however it crashes occasionally (see bug 12075: http://bugs.winehq.org/show_bug.cgi?id=12075). I am interested to hear from other endnote users and their experiences, especially whether you run it together with word or openoffice and why (I have not made up my mind yet). Thanks

Suppose I have the following: x1<-as.vector(rnorm(10)) x2<-as.vector(rnorm(10)) x3<-as.vector(rnorm(10)) x4<-as.vector(rnorm(10)) x5<-as.vector(rnorm(10)) x6<-as.vector(rnorm(10)) x7<-as.vector(rnorm(10)) x8<-as.vector(rnorm(10)) x9<-as.vector(rnorm(10)) x10<-as.vector(rnorm(10)) I would like the mean of x1 to x6 for each vector position. I would do something else

Hello: I successfully installed Solaris10 nv77 x86 on my Compaq NX6325 laptop with the following specs: - Mobile AMD Turion 64 X2 TL-52 (dual core 64bit). - 4GB RAM. The installation destination was an external 120GB USB 2.0 drive. I was able to successfully boot into regular Solaris, but not into xVM Solaris. Meaning, after highlighting the xVM menu item and pressing enter, the screen turns

Hi, I just had 7.0-RELEASE crash again, whilst kldloading the uplcom.ko module in multi-user mode with X running, and no USB serial devices plugged in. The T43 immediately resets, I don't get a chance to drop into a debugger. This seems like a pretty serious USB regression. Is anyone looking into it? Are these things a thing of the past with the "new" USB code? thanks BMS

I'm trying to install (I know is garbage...but trying doesn't hurt anyone :D) Corel Paint Shop Pro X2 I've installed via winetricks various libs such .NET, msxml2, msxml3 and various Virtual Studio Runtimes... But it always stuck with these lines: fixme:mountmgr:harddisk_ioctl unsupported ioctl 74080 What does it mean? What could be? There are any chances to get it working?

Is there a special command or anything to get a "make" process take advantage of SMP with the AMD x2. I mean when I type make is it dispatching 2 compiles at a time? How do know it is or how do I tell it to take full advantage of the DUAL processor. Thanks, jerry

Hello, My name is George Pantopoulos, i am a phd student in the Dept. of Geology, University of Patras, Greece. I am studying the statistical behaviour of bed thickness datasets taken from outcrops. Until now, 4 statistical distributions seems to fit my datasets: power law, lognormal, lognormal mixture with 2 modes and exponential. I already used the MIX package of R to detect a possible 2 mode

Dear all, I've been delighted to just notice that Cohen's formulas for Effect Size 'w' and the associated power have been implemented in the 'pwr' package (thanks to St?phane Champely and others).. There is one aspect, though, that perplexes me. I'm doing some last minute post hoc analyses, meaning that my sample size (N=3404) has been long fixed, and I'm

Hello All, I'm running hardy heron and wine 0.9.60. Endnote X1 installed from the cd with no problem but I have never been able to run it. Oddly I can run everything else (it has another .exe for updates). As per the AppDB listing I've tried running it using different winvers but still no luck. In web searching this error I found a comment on a different forum indicating others with this
