Hi all, i installed the ggplot2 package via install.packages(), but the gplot function was not recognized in R console command. Is there any paths to configure? The error message reports that the function was not found. Thanks Ricardo ____________________________________________________________________________________ Be a better friend, newshound, and

Hi, my name is Ellen. I want to ask you about R Code. I got a code for extracting a pixel value, but I can't compile it..  It is said "Error in is.data.frame(x) : object 'lena' not found" Here is the original full code: library(pixmap) lena <- read.pnm("oldlennablur.pgm") write.table(lena@grey,"mylenna", quote=FALSE, row.names = FALSE, col.names=

Dear All, Sorry to bother I want to write a function in R using if Say I have a dataset x, if x[i]<0, then x[i]=x[i], if x[i]>0, then x[i]=0 for example, x=-3:3, then using the function, x becomes [-3,-2,-1,0,0,0,0] I write the codes as follows, gjr=function(x) {lena=length(x) for(i in 1:lenx) if (x[i]<0) return (x[i]) if (x[i]>0) return (0) x} but then, doing gjr(x? it only

Hello! I am trying to export a data-file from SAS to R. It says in the R program that the SAS file should be in XPORT-format. I assume that the file should have and .xpt extension. But when I try to open the file in R I get only the message "compressed" written all over. So, probably I should un-compress the file in the R-program, the question is how? Very greatful for quick help!

Hi I want to du a sensitivity analysis using Latin Hypercubes. But my parameters have to fulfill two conditions: 1) ranging from 0 to 1 2) have to sum up to 1 So far I am using the lhs package and am doing the following: library(lhs) ws <- improvedLHS(1000, 7) wsSums <- rowSums(ws) wss <- ws / wsSums but I think I can't do that, as after the normalization > min(wss) [1]

Hi all and thanks in advance. I am regressing Time and Weight, and then predicting Weight at different Time. The format of the Time data is day/month/year. How can I get R to use time series data such as this? Keith -- M. Keith Cox, Ph.D. Alaska NOAA Fisheries, National Marine Fisheries Service Auke Bay Laboratories 17109 Pt. Lena Loop Rd.

Hallo, zur Analyse von Daten zum Artenreichtum von Pflanzen, habe ich ein Glm (glm) und anschlie?end eine Anova (anova) durchgef??hrt. Nun m??chte ich f??r die signifikanten Einflussfaktoren einen Post Hoc Tukey Test durchf??hren, um zu ermitteln in wie weit die einzelnen Faktorstufen sich signifikant voneinander unterscheiden. Mit dem Befehl (TukeyHSD) komme ich nicht

Hello all, I have a matrix whose column names look like a1 a2 b1 b2 b3 c1 c2 1 2 3 7 1 3 2 4 6 7 8 1 4 3 Now, I can have any number of a's. not just two as shown above and same goes for b's and c's. I need to extract all the a's columns and put them in another matrix, extract all b's columns and put them in some matrix

Hi, I've a matrix that contains 4 replicates of each rowname. (4 a's, 4 b's, 4 c's in no particular order) Like this: # c 32 a 1 b 4 c 87 c 34 b 54 a 23 a 12 b 9 a 3 b 87 c 43 There are a couple of more columns but I'm using the above as an example I need to sort it so that the same rownames appear together in alpahbetical order. Like this: # a 1 a 23 a 12 a 3 b 4

Dear R helpers, I have a problem with exporting a chart (to any format). The graphic device becomes inactive and I get the 'Error: invalid graphics state' error message. I searched the help, web and FAQ but couldn't find the solution. This is my code: I chart a histogram for differences in R2 by sample size (an extract from the data is below). Altogether I have n=2500 observations

I would like to calculate a first and second derivative and am having problems finding a simple solution. My syntax may be off as I am not a mathematician, so pardon ahead of time. data: t<-seq(0,4, by=.1) The function is: H(t) = t^3-6*t^2+5*t + 30 from here I plot the curve: plot(x,y ,xlab="x-values", ylab="f(x)", type="l") But would like to similarly plot the

Hi everyone, I'm using R, Latex and Sweave for some years now, but today it confuses me alot: Running Sweave produces only figures in .pdf format, no .eps figures. The header looks like this: <<echo=TRUE, fig=TRUE, label=Fig1>>= There was no error message. Does anybody have an idea? Any changes in the Sweave-package? Or a missing driver or something like that?

Hello, hopefully simple question, but I cannot find the answer. I need to change the color from the standard default. Still want the scaled colors, but need different colors for different graphs. Code is: wireframe(z ~ y*x, mat.df, drape = TRUE, zlab = list("Water mass error (%)",rot=92), zlim=c(-50,180), xlab = list("Resistance error

I would like to create a point plot with the following two sets of points: #1 plot(Day,Total) and #2 (Day,cons_hat). Total is the actual value seen and cons-hat is a predicted value. If possible, I do not want to stack them as they are quite long. (FYI, I did use the reshape on a previous post, thanks, but this one is different).

Hi, I would like to add a color under a lm line and not the plotted line. Is this possible? In the example, I do not want the area under the curve red, but rather under the llm line. x=seq(0,5,len=100) y=-(x-5)^2 llm<-lm(y~x) plot(x,y) polygon(c(x,x[length(x)]), c(y, y[1]), col='red') abline(llm) keith -- M.

Greetings! I am trying to compare simulated environmental conditions from a model against a recruitment time series for a species of crab by first dropping 5 data points, and then using the remainder to attempt to simulate the missing data as a measure of best fit and using the following code: all.mat<-as.matrix(comb,ncol=ncol(comb),nrow=nrow(comb)) obs<-as.matrix(R2,24,1) mod<-all.mat
