i am working on the project to analyze hedge fund performance, i would appreciate that if you guys could spare some time helping me out with the R code. Thanks. The senario is: i applied BOXPLOT() to plot the performance of all hedge funds with 7 strategies. And right now in this boxplot I need to plot the points of 30 individual hedge funds from my portfolio. And I applied POINTS() and

Hi R folks, In my previous post I forgot to mention that I was new to R. I was really grateful for your quick help. I have two further questions: 1) In the graph of a regression line I would like to show one specific residual yi obs - yi pred (let's take the person whose residual is 76). How do I add a bracket to this vertical distance and name it? I'am getting stuck after the

Hi All, I'm trying to do a Scatterplot (package: car), and add a line (just for reference). There is my code: #------------------------------------Code--------------------------------------------------- library("car") library("calibrate") G_T<-c("car","bike","boat") ave<-c(80,10,45) perf<-c(100,80,75) df2<-data.frame(G_T,ave,perf)

Hi guys, I am doing a project to evaluate the 7 individual fund performance from a portfolio compared with all fund performance utilizing the same strategy. Lets say in total there are 10 strategies and in the portfolio there exist 5 strategies. First, i use the BOXPLOT() and SUBSET() to produce the box plot of all the 5 funds performance individually: #identify funds in strategies within

Hi R users, I would like to add year information to each point in a scatter plot. The following example shows what i mean: df=data.frame(year=c(2001,2002,2003),a=c(8,9,7),b=c(100,90,95)) df plot(b~a,data=df) Now, I would like to see which point belongs to 2001, 2002 and 2003 in the above graphic. Thank you very much, ozan [[alternative HTML version deleted]]

Hi everyone, i?m trying to graphically display distributions with r and i?m working with makrodata from the WVS. the command i?m using is > plot (Makrodata$v11, Makrodata$v12, xlab="Democracy Score Economist", > ylab= share religious people") i?m having an additional variable that identifies respectively labels the

Dear all, I have a question about the 'sdev' value returned by the princomp function (which does principal components analysis). On the help page for princomp it says 'sdev' is 'the standard deviations of the principal components'. However, when I calculate the principal components for the USArrests data set, I don't find this to be the case: Here is how I

Hi All, I have tried to find an answer within documentation, but I cannot: o How can call a class "slot" without knowing the name a priori? E.g., let's say I use the "pcaMethods" library to create a "pcaRes" object. How can I call parts of that object without using the specific names of the object in the call? example code: library(pcaMethods)

Hi all, I have a difficulty to calculate the PCA scores. The PCA scores I calculated doesn't match with the scores generated by R, mypca<-princomp(mymatrix, cor=T) myscore<-as.matrix(mymatrix)%*%as.matrix(mypca$loadings) Does anybody know how the mypca$scores were calculated? Is my formula not correct? Thanks a lot! Phoebe [[alternative HTML version deleted]]

Hi, I need to export to LaTex the summary of a PCA. So: myPCA <- prcomp(myDF) mySummary <- summary(myPCA) # print(xtable(mySummary)) How can I export to LaTeX not all the summary but only the first nPCs?? Best Riccardo

Hi, I was trying as well as looking for an answer without success (a bit strange since it should be an easy problem) and therefore I will appreciate you help: My simple script is: # Loadings data of 5 columns and 100 rows of data data1<-read.csv("C:/?/MyPCA.csv") pairs(data1[,1:4]) pca1 <- princomp(data1[,1:4], score=TRUE, cor=TRUE) biplot(pca1) The biplot present the data

Hi, In the plot function I want to label x axis as the numbers between 1 and 12 (so 1, 2, 3, 4, 5, ..., 12). How should I do it? The range of x values are different than this range. Thanks! Kind regards, T. Bal [[alternative HTML version deleted]]

Hi, Does anyone have any ideas on how to show greek letters on the x and y axes? I have tried > plot(x,y, xlab=expression(delta), ylab=expression(gamma)) but the output on the x-axis is "d" and on the y-axis it is "g". Any help will be very much appreciated. Cheers, Sam.

I have a basic question concerning how LLVM assigns labels to the LHS of an SSA assignment. My impression from the interface is you can pick a string which becomes the label for the result. However if you multiple labels which share the same name in a function a number gets added to the end of the label (is this correct?). In cases where you need to know what these resulting labels are is it

Hi guys! I was reading to the platinum games list and I noticed that many are accompanied by the "steam" label (i.e. day of defeat steam): what does that mean? Can't I use the normal game dvd to install the game? Sorry but I'm quite a wine noob! Thanks in advance!

When doing a network install with a kickstart file, how do I prevent the partition label on the root filesystem from being changed? I'm building a system with multiple flavors of CentOS in separate partitions and I would really like to have the partition labels be something meaningful. So far, the only idea I've come up with is to use the --noformat flag on the partition definintion in

Hi all. I've found that also in R-2.3.0 there is the bad labelling previously found in R-2.2.1. x <- ts(1:3) plot(lag(x,1),x) #labels 1 and 3 are superposed on the first point. plot(lag(x,1),x, xy.labels=as.character (1:2)) #this is ok xy <- ts.intersect(lag(x,1),x) plot(xy[,1],xy[,2]) #this also is ok The same problem is shown by lag.plot, which in turn calls plot.ts. Also note that

Dear R-helpers! Using logarithmic axes sometimes results in an odd labelling. In some cases, only half of the axes do have labels. Hmmmm. I've played around with par(lab=c(5,5,7)) but that didn't help. An example: ---- begin example ---- x <- c(0.12, 0.3, 0.53, 1.1, 1.8, 2.6, 4.5) y <- c(0.012, 0.021, 0.032, 0.055, 0.1, 0.2, 0.35) plot(x, y, log="xy",

Hi. I'd like to produce a barplot where only the lowest value and the highest value are labelled on the x-axis. E.g. I might have a list of numbers and frequencies: barplot( c( 2, 2, 0, 4, 2 ), names.arg=c( 1, 2, 3, 4, 5 ) ) where the data is a set of counts for some values between 1 and 5. I'd like to have a barplot where only the extremes 1 and 5 are labelled. How do I do this?

Dear colleagues, I have a great problem in using "expression" for axes labels. I want the labels in bold face (i.e.: par(font.lab=2)). When typing boxplot(y ~ groups, names = "" , xlab = "", ylab = "", axes = F) axis(side=1, at=c(1,2), xlab=c(expression(H[2]*O),"others")), I do not get a bold face labelling. Does anyone know, how I could
