How can I set the ylim in individual panels of a "multiple" plot.ts? The panels are all scaled to fully fit the series inside. But I need specific scales, and colors .... Here is an example: plot.ts(cbind(1:10,1:10/10),ylim=c(0,3)) # ylim has no effect Can someone more knowledgable please explain how to use the panel= option correctly, thanks! Cheers, m

I need to modify the graph of the autocorrelation. I tried to do it through plot.acf but with no success. 1. I would like to get rid of the lag zero 2. I would like to have numbers on the x-axis only at lags 12, 24, 36, 48, 60, ... Could anybody help me in this? Any help will be appreciated Thank you for your attention Stefano [[alternative HTML version deleted]]

Hello All, I was wondering if it's possible to reshape data from long to wide in R without using a "timevar". I've pasted some sample data below along with some code. The data are sorted by Subject and Drug. I want to transpose the Drug variable into multiple columns in alphabetical order. My data have a variable called "RowNo" that functions almost like a

I recently asked this question, but I didn't get an answer on this part of my question: What hardware would be able to do this with ease: I must install a samba server as PDC for my school. The server would authenticate users using openldap (on the same server). And if possible, I would also run an intranet on it (apache, php, mysql). There would be about a hundred (maybe 150 later on)

Hi Everyone, I am trying to understand the unstack() function but after struggling for two days, I have given up. More specifically, I am trying the exercises at the end of Chapter 1 of Data Analysis and Graphics Using R by Maindonald and Braun, 2nd ed. Exercise 18 (p. 41) asks to unstack the Rabbit data frame from the MASS package to get a certain data frame that is shown in the exercise.

I've been reading the R mail archives and I've found a lot of messages with this same kind of problem, but I can't understand the answers. Can one of you try to explain this to me? Here's my example. Given a regression model and a variable, I want to use unstack() on the vector of residuals and make some magic with the result. But unstack hates me. PCSE <- function

Ok I'll try that in the morning and will get back with the resilt.

Folks, I have the following dataframe: > x <- structure(list(name = c("EU B", "EU B", "EU B", "EU B", "EU B", "EU B", "AU A", "AU A", "AU A", "AU A", "AU A", "AU A"), date = c("2010-10-11", "2010-10-12", "2010-10-13",

Dear R users, I'm having some problems with the stack() and unstack() functions, and wondered if you could help. I have a large data frame (400 rows x 2000 columns), which I need to reduce to a single column of values (and therefore 800000 rows), so that I can use it in other operations (e.g., generating predictions from a GLM object). However, the problem I'm having can be reproduced

Hi all, I'm having a problem restructuring my data the way I'd like it. I have data that look like this: Candidate.ID Specialty Office Score 110002 C London 47 110002 C East 48 110003 RM West 45 110003 RM

Dear R-help, First of all, thank you VERY much for any help you have time to offer. I greatly appreciate it. I would like to write a function that, given an arbitrary number of factors from a data frame, tabulates the number of occurrences of each unique combination of the factors. Cleary, this works: > table(horse,date,surface) <SNIP> , , surface = TURF

One would normally want the original order that so that one can stack a list, operate on the result and then unstack it back with the unstacked result having the same ordering as the original. LL <- list(z = 1:3, a = list()) # since we can't do s <- stack(LL,. drop = FALSE) do this instead: s <- transform(stack(LL), ind = factor(as.character(ind), levels = names(LL))) unstack(s)

A quick question that I've had only partial success in answering. I have a multivariate dataset, and would like to extract some simple univariate information from it grouped by treatments, etc. I am encountering two problems however Note: I am importing my data with my_data <- read.csv("/path/data.csv") 1) Scoping of unstack If I attempt sorted_data <- unstack(response,

Hello All, I'm having some trouble reshaping my data from wide to long format. I have tried using both the reshape function and package. Although I haven't worked much with the reshape function, I have found the reshape package useful and intuitive for reshaping data from long to wide format. However, going the other way has me stumped with this type of data. My data is set up, roughly,

Dear all, I have a data frame with 2 columns and 102500 rows. The data looks like below V1 V2 8098 110000....... 9099 001100....... 0023 110011....... 6545 111111....... . . . . . . . . . . I want to split the colums like this ; V1 V2 V3 V4 V5 V6 v7 8098 1 1 0 0 0 0 ...... 9099

Seems like this should be easy but I'm struggling a bit. How do I rearrange a data frame to go from the first one to the second shown below ?

Hi all, I have been struggling with this problem for a few days. I have a data table like this: gene rpkm1 diff1 rpkm2 diff2 gene1 23 50 13 120 gene2 111 220 827 1200 gene3 75 998 71 910 And I want to re-format it so that, for each gene, I have a 2x2 contingency table, such as: gene rpkm diff gene1 23 50 gene1 13 120 gene2 111 220 gene2 827

I would appreciate some advice on the following task. I have some data that currently looks like this: t1 <- data.frame(id=c(1,1,2,2), aspect=c("A","B","A","B"), score=c(10,9,11,12)) I'd like it to look like this: id A B 1 10 9 2 11 12 reshape() looks like a good candidate for this job but I'm not really sure about the roles of

dear all, apologizes for bothering with a probably stupid question but I really don' t know how to proceed. I have a dataset which look like df a <- c(1,2,3,4,4,4,5,5) b <- c(11,7,4,9,8,3,12,4) df <-cbind(a,b) I would like to have one which looks like this: a 1 11 2 7 3 4 4 9 8 3 5 12 4 a are vertex of a network, b the edges. In the data the lenght of a is about 50000 I read
