...shing in a journal that is very picky about their graphics formats. It is more efficient for me to get the final picky details of each graph done by our graphics department, who use Windows CorelDraw. The problem is that I have not yet been able to give them a vector graphics format that can be ungrouped in CorelDraw for editing. Bitmaps cannot be ungrouped <www.eatbywest.com/pub/vectorbitmap/>. The standard postscript that I am producing in R cannot be ungrouped either, and comes into CorelDraw looking fragmented. While I may be doing something odd in the production of my postscript file...

I'm hoping the community knowledge can help me out here. I have found great value in R, especially using it to generate charts, but I am still scaling the learning curve in a number of ways. I am looking plot one grouped line and one ungrouped line in a lattice plot. I can plot one grouped line like this (the line's color in each panel becomes dependent on the newpool value): xyp<-xyplot(cpucap~date|zone,data=df,type="l",groups=newpool,auto.key=list(points=F,lines=T), main=paste(df$server[1]," CPU Cap...

Thanks for helping me out with the thing of quotation marks. I finally could save time running programs at the university and home. One additional question for all of you. I'm starting to be familiar with multinomial regression models. Actually I'm doing some exercise with the pneumo data that appears in Faraway library. The database has 24 observations and I want to study the probability

Dear Masters, first I'd like to wish u all a great 2011 and happy holydays by now, second (here it come the boring stuff) I have a question to which I hope u would answer: I run a logistic regression by glm(), on the following data type (y1=1,x1=x1); (y2=0,x2=x2);......(yn=0,xn=xn), where the response (y) is abinary outcome on 0,1 amd x is any explanatory variable (continuous or not)

...9;s data, with both regression lines and data ellipses, and I must be doing something wrong, because the lines do not intersect at \bar{x}, \bar{y}. The problem is likely in the line for x.y, but I don't know how to specify that correctly. The data is read in grouped form( galton), and then ungrouped (galton2): galton <- read.table("~/sasuser/data/galton.txt", header=TRUE) # ungroup galton2<-galton[rep(1:nrow(galton), galton$frequency), 1:2] attach(galton) sunflowerplot(child, parent, number=frequency, xlim=c(61,75), ylim=c(61,75), xlab="Child height", ylab=&quo...

Buenas tardes Estoy haciendo un análisis LDA y me gustaría cambiar el nombre de los topics a la hora de visualizarlos y en vez de que se llamen 1,2,3...darles un nombre. ¿Es posible en este código? lda22 <- LDA(reviews_dtm, k = 22, control = list(seed = 1234)) lda22 %>% tidy() %>% group_by(topic) %>% top_n(10, beta) %>% ungroup() %>% mutate(term =

I've noticed that the implementation of Kendall's Tau in R is O(N^2). The following reference describes how it can be done in O(N log N): A Computer Method for Calculating Kendall's Tau with Ungrouped Data William R. Knight Journal of the American Statistical Association, Vol. 61, No. 314, Part 1 (Jun., 1966), pp. 436-439 http://www.jstor.org/pss/2282833 I'm interested in contributing an implementation of this algorithm to R. However, I have a few questions: 1. Would it likely be ac...

Hello, (apologies, I'm not entirely sure whether this question is about R or my limitations with PowerPoint). I've submitted a paper (which has been accepted) but the journal now require me to submit graphs that are "editable in PowerPoint". I would be grateful for suggestions as to how I should do this. The best route seems to be to copy-and-paste the figures from the

Hi Folks, I have just started using dplyr and could use some help getting unstuck. It could well be that dplyr is not the package to be using, but let me just pose the question and seek your advice. Here is my basic data frame. head(h) subject ageGrp ear hearingGrp sex freq L2 Ldp Phidp NF SNR 1 HALAF032 A L A F 2 0 -23.54459 55.56005 -43.08282

Hi, I am writing a function to dynamically create column names and fill those columns with some basic calculations. My function "demo_fn" takes argument "blup_datacut" and I like to use the contents of those arguments to dynamically create new columns in my dataset. Please note that I have another function called "calc_gg" within the function "demo_fn".

Dear RHelp-list, ?? Using dplyr and the group_by approach on a dataframe, I want to be able to apply a specific action according to the group name. The code bellow works, but I am not able to write it in a more esthetic way using dplyr. Can somebody help me to find a better solution ? Thank you Best regards Laurent df_test <- data.frame( x1=1:9, x2=1:9,

I have used plor() to model a rather large 3-category dataset (~1500 data points, ~15 independent variables); from the resulting model (with a deviance slightly below the residual degrees of freedom), the training data are placed in only the two extreme categories. Though the result appears to indicate that there's only a relative 'narrow' bin for the medium group, [and when the

Hi, I don't know about the lazyeval package or what you are trying to do but to answer the main question "How to create columns dynamically using a function?" I would do something like that: # dataset dem <- structure(list(id = c("L1", "L2", "L3", "M1", "M2", "M3"), TEST_SET_NAME = c("A", "A",

...onstructed two types of data sets. On Rfile-01.Rdata (attached here) are data frames, data.1 and data.2. The information is identical but the data are arranged differently between these two data frames. Data frame, data.1, groups frequencies by subject, day and treatment. Data frame, data.2, is ungrouped. Consistency of these data frames is substantiated by computing these tables: ftable(xtabs(response ~ expt + subject + day, data = data.1)) ftable(xtabs(as.numeric(response) - 1 ~ expt + subject + day, data = data.2)) If I ignore the repeated measurement aspect of the...

I am trying to test goodness of fit for my legalistic regression using several options as shown below.  Hosmer-Lemeshow test (whose function I borrowed from a previous post), Hosmer–le Cessie omnibus lack of fit test (also borrowed from a previous post), Pearson chi-square test, and deviance test.  All the tests, except the deviance tests, produced p-values well above 0.05.  Would anyone please

It has always been my understanding that deviance for GLMs is defined by; D = -2(loglikelihood(model) - loglikelihood(saturated model)) and this can be calculated by (or at least usually is); D = -2(loglikelihood(model)) As is done so in the code for 'polr' by Brian Ripley (in the package 'MASS') where the -loglikehood is minimised using optim; res <-

Hi everyone, I am trying to generate a conditional dummy variable ?X" with the following rules set X=1 if Y is =1, two years prior to the NA. [0,0,NA]. For example, if the pattern for Y is 0,0,NA then the X variable is =0 for all the two years prior to the NA. If the pattern for Y is 0,1,NA or 1,0,NA then the X =1 . To be clear, if 1,1,NA then the X=1 that first specific year, it
