I have done the following using readLines directory <- "~/" files <- list.files(directory) data_frames <- vector("list", length(files)) for (i in seq_along(files)) { df <- readLines(file.path(directory, files[i])) df <- df[-(1:13)] df <- data.frame(year = substr(df,1,4), month = substr(df, 6,7), day =

I'm using the rcorr function from the Hmisc library to get pair-wise correlations from a set of observations for a set of attributes. This returns 3 matrices; one of correlations, one of the number of observations seen for each pair and the final of the P values for each correlation seen. >From these three matrices, all I wish to do is return a single matrix based on the first correlation

I've been trying to filling in the missing variables in a matrix with the mean from the column they are in. So the following code does this just fine. #3X3 matrix where the middle number is missing. data=matrix(c(1:4,NA,6:9), 3, 3) #replace missing values in an vector with the mean of the vector fill_in_NA<-function (x) { x[is.na(x)]<-sum(x[!is.na(x)])/length(x[!is.na(x)])

Hi, I need to represent data structures in a figure.stuff like trees with nodes and pointers etc.can someone guide me to a package that does this? -- Rajesh.J [[alternative HTML version deleted]]

Dear R users, is there a way to define the color of the title for the legend in lattice? The help page on xyplot has a lot of details on key options just as the new book, but no mentioning of a color attribute for the title. Should I use ltext or is there any other way? Best wishes, Erik [[alternative HTML version deleted]]

Hi, I'm very confused about R structures and the methods to go with them. I'm using R for microarray analysis with Bioconductors. Suppose without reading the documentations, what's the best way to explore a data structure when you know nothing about it? I am currently using is() / class() to see what the object is. str() / attributes() to probe inside the object, and

Hello, all, I have a dataframe of three rows and umpteen columns. I want to show the maximum, minimum, and median with a vertical line and a central dot (I'd use a boxplot, but with only three data points, that's overkill; I can't just use points, because of overlap and some of the other data plotted on the graph). This works: > boxplot(data_frame,

I have a small matrix where the columns represents a ranking and the values are the number of times each ranking was obtained eg 1 2 3 x 1 2 0 y 0 1 2 z 2 0 1 I'd like to be able to return an average of the ranking obtained average x 1.67 y 2.67 z 1.67 Whats the nicest way to do this? I'm new to the language and looking for an elegant solution :) Thanks Ben

Dear R-helpers, let us assume, that I have the following dataset: a <- rnbinom(200, 1, 0.5) b <- (1:200) c <- (30:229) d <- rep(c("q", "r", "s", "t"), rep(50,4)) data_frame <- data.frame(a,b,c,d) In a first step I run a glm.nb (full code is given at the end of this mail) and want to predict my response variable a. In a second step, I would

Ok, so basically I have a dataframe named data_frame data_frame contains: startdate startprice endpricethreshold1 endpricethreshold2 endpricethreshold3 all of these endpricethresholds are true/false binary vectors. They are true or false depending on whether the endprice was above or below whatever the endpricethreshold is. now I want to try to use lets say the general linear model to have

Hello, I'm looking for an easy way to display a data.frame (or other variables) page by page, similarly to what is possible on a file using the more command in a standard UNIX shell. Any help would be greatly appreciated. Thanks Alexandre [[alternative HTML version deleted]]

So I'm noticing from the docs/ on Asterisk Addons 1.4.10 that the database structure for cdr_mysql is: CREATE TABLE cdr ( calldate datetime NOT NULL default '0000-00-00 00:00:00', clid varchar(80) NOT NULL default '', src varchar(80) NOT NULL default '', dst varchar(80) NOT NULL default '', dcontext varchar(80) NOT NULL default '', channel

When I run a summary(anova) I get output for all of the elements (columns) as these are multiple - single anova results. Can I store the F values? I can't find the attribute of the fitted model attributes(fit) that stores these F values, and for that matter, P values.
