similar to: Showing NAs when using table()

I have two factors, WC and WD. If I want a table including all the values of each factor, including NAs, I can get a table by going: table(as.character(WC),as.character(WD),exclude=c()) Is there an easier way? I guess this is a feature request for table() Thanks, Robert. ---- Robert King, Australian Environmental Studies, Griffith University, Australia 3875 6677 Robert.King at

Estimados usuaRios: deseo hacer una consulta, debo realizar una prueba no paramétrica a un conjunto de datos que posee una variable de respuesta con tres factores que poseen interacción, o al menos debo probar ello. Es decir, realizar una prueba Scheirer-Ray-Hare o de Contrastes de rangos alineados. Estuve trabajando el paquete ARTool aunque no me queda claro

Dear List, I've been looking tirelessly for a solution to this dilemma but without success. Perhaps someone has an idea that will guide me in the right direction. Suppose I have the following data.frame: DF = data.frame(X = c(114.5508, 114.6468, 114.6596, 114.6957, 114.6828, 114.8903, 114.9519, 114.8842, 114.8579, 114.8489), Y = c(47.14094, 46.98874, 46.91235, 46.88265, 46.80584, 46.67022,

Dear R users, I have received a table in the following format: id a b c1 c2 d1 d2 1 1 1 65 97 78 98 2 1 2 65 97 42 97 3 2 1 65 68 97 98 4 2 2 65 97 97 98 Factors of the design are: a, b, and e, where e has levels c and d. The levels c and d then have 2 replicates (r) each. Now I would like to get: id a b e r value 1 1 1 c 1 65 2 1 1

Is there a simple way to calculate summary statistics for all the matrices or dataframes in a list? For example: > z <- list(matrix(c(2,2,2,2), ncol = 2), matrix(c(4,4,4,4), ncol = 2)) > z [[1]] [,1] [,2] [1,] 2 2 [2,] 2 2 [[2]] [,1] [,2] [1,] 4 4 [2,] 4 4 > I would like to calculate, for example, the mean value for each cell. I can do that the hard

Hello, I have an unbalanced panel dataset and would like to exclude all objects that don't appear at least x times. Therefore, I would like to include a column indicating for every line how many periods are available, e.g. id, year, number 1, 2000, 3 1, 2001, 3 1, 2002, 3 2, 2001, 1 3, ..., ... This would allow me to exclude companies by setting "subset=number>=x". However, I

Hi all, i'm trying to run a two-sample t-test. i have a longitudinal data that looks like this: idn age class 1 22 1 1 22 1 1 22 1 1 22 1 2 63 3 2 63 3 2 63 3 3 43 2 3 43 2 3 43 2 3 43 2 3 43 2 3 43 2 4 37 1 4 37

I am using read.table to import a text file within R.   There are several "errors" in my text file.  An "extra" quotation mark has inadvertently been included within a few text fields.   e.g. for a pipe (|) delimited text file, I have something similar to this:   1|7|30| "dog" 2|6|25| ""cat" 3|4|20|"" 4|5| 56| "mouse" 5|3|56|

Hi R-Wizards: I've looking through the R docs and have yet to find what I'm looking for and have tried a few intermediate steps to now avail yet and rather than spend another few hours looking for the solution, I figured I would post a message. I have a matrix (actually a set of them) that I want to pull all the names of the non-zero columns into a vector/list for further processing:

R-devel, Below is a simple example calling split and unsplit on a numeric vector of length 2 where 'f' is c(1,NA). > unsplit(split(c(1,2), c(1,NA)), c(1,NA)) [1] 1 0 I noticed that the call to vector in unsplit gives us 0 as the 2nd element of the result. Is this the intended result, as opposed to NA? Thanks for your help, Jeff -- Jeff Enos Kane Capital Management jeff at

Hello all, I'm just starting to learn R and I heard a good way of doing that was R Commander. For my work I use a lot of time series, so I installed (and loaded) R Commander with epack. When I go to Ts-Models, after loading my data, I click on ARIMA Models tab. I load my variable D1 Ln Demand (1st differenced ln demand). I set my regular and seasonal p d q settings hit run and I get: [1]

Hi, Suppose I have the following tabular data: 1729_at | TRADD | TNFRSF1A-associated via death domain | protein-coding 1773_at | FNTB | farnesyltransferase, CAAX box, beta | protein-coding 177_at | PLD1 | phospholipase D1, phosphatidylcholine-specific | protein-coding What is the right separator used for read.table function? I tried this: dat <-

I've been trying to build a bundle with the R-devel snapshot from yesterday. (Yes I know it is unstable and just tell me if I shouldn't be trying to do this yet.) It is failing with the message tar : /dev/rmt/0 : Permission denied It happens after "removing junk files" and just after the message "building dse_2000.9-1.tar.gz" It looks to be coming from the line in

R-devel, I'm in the process of choosing a name for a new package. I've already decided that the name will have two parts, 'portfolio' and 'sim', but can't decide between 'portfolioSim' and 'portfolio.sim'. Is there any good reason to choose one over the other? Thanks in advance, Jeff -- Jeff Enos Kane Capital Management jeff at kanecap.com

Hi all, Assume that I have a data set (“xcv”) with several variables and some of the variables have a missing observation represented by -9 as shown below. I want to exclude these observations from the analysis ( as a NA). Is there a command that I can do it for the entire data set rather than one by one for each variable ( tmp <- xcv[xcv$v1 != -9, ]) V1 v2 v3 v4 11 23

Hello, I am drawing contour lines for a function of 2 variables at one level of the value of the function and want to include a small arrow in any direction of increase of the function. Is there some way to do that? Below is an example that creates the contour lines. How do I add one small arrow on each line in the direction of increase of the function (at some central point of the contour
