Force "square" crosstabulation
Hello list members, I'm looking for a way to force the results of a crosstabulation to be square - that is, to include 0 values. For example: table(letters[1:4],letters[c(1:3,3)]) yields: a b c a 1 0 0 b 0 1 0 c 0 0 1 d 0 0 1 I would like to return: a b c d a 1 0 0 0 b 0 1 0 0 c 0 0 1 0 d 0 0 1 0 Any suggestions? Thanks! -- Manuel A. Morales http://m...

multiple 2 by 2 crosstabulations?
...to export summary statistics to Latex in the form of a table. I want specific summary statistics by crossing numerous variables 2x2 AT ONCE. In each cell I would like sometimes to have the median (Q1 - Q3), or frequency and proportion, etc. CrossTable, xtab, etc... do not allow for multiple 2 by 2 crosstabulation. The table would look like this:          var_1  var_2     var3, ... var_1   a        b            c  var_2   d        e            f var_3   ..     ...         ... with a, b, c, ... the results of each crosstabulation. I have continuous and categorical variables. Any idea? Thank you very much,...

CROSSTABULATION
I want to form a 3x3 crosstabulation for the signs of two vectors (i.e. Negative, Zero, Positive). The problem is that I am simulating the data so for some iterations one of the categories is absent. Thus the resulting table shrinks to 3x2. I want it to be 3x3 with zero column corresponding to the missing category. Moreover, I have tr...

crosstabulation and unlist function
...ello R-users, My toy example: aa<-c(1:5) bb<-c(NA,2,NA,4,5) cc<-c(1,2,NA,4,NA) dd<-c("A","B","B","A","C") df<-data.frame(aa,bb,cc,dd=as.factor(dd)) table(unlist(df[,1:3])) Can anyone point me to what function let's me do a crosstabulation between table(unlist(df[,1:3])) and df$dd? I want to find out when dd==A (or B, or C) how many times do the values 1, 2 ,3,.. appear in df[,1:3]? Thank you very much! Eugen Pircalabelu

how to handle 'multiresponse' variable?
...tiple responses are elements of character vectors, like this: $ P124 :List of 2956 ..$ : chr "2" "4" ..$ : chr "1" "2" ..$ : chr "NA" ..$ : chr "3" "4" ..$ : chr "3" I need to compute crosstabulation on this variable, to make crosstabulation where this variable is a factor variable (responses of this variable are categories, in which i need to compute distributions of other variables). And i need to do crosstabulation with 'weights', like in xtabs(w~f1+f2). Is any way exists to do...

crosstabulation
Hi, I find difficult to read crosstabulated data without percentages, so I wrote this dirty function that may be useful to others. It only works up to 3 dimensions since I am not very good at programming in R. I would appreciate if someone else has a better similar function or can improve this one. As an example of use: > x<-rbinom(100,1,.3) > y<-rbinom(100,1,.3) >

"subscript out of range" message
Hi All: I was recently working with a dataset on arsenic poisoning. Among the variables in the dataset, I used the following three variables to produce crosstabulations (variable names: FOLSTAT, GENDER, ASBIN; all three were categorical variables, FOLSTAT denoted follow up status for the subjects and had seven levels, GENDER denoted sex (two levels: male,female), and ASBIN denoted binarized arsenic concentrations (two levels: "<0.05", ">0....

Crosstabs in R
Before I reinvent the wheel, I have need for a relatively straightforward crosstabulation (2 x n) function. I know that R has table(), ftable(), xtabs(), and summary(xtabs()), but none of these produce a fully "tricked" out cross-tabulation with marginal totals, expected cell frequencies, and an array of statistics about the contingency table. Is there a more complete (so...

crosstabulation of means
Hello, I am trying to print a crosttabulation of mean,sd,n for a continuous variable crossclassified by anoother/s grouping variables. I came up with: xtab2 <- function(x,g1,g2) { funy <- function(z) list(mean(z,na.rm=T),sd(z,na.rm=T),length(z)) aa <- by(x,list(g1,g2),funy) bb <- matrix(unlist(aa),nrow=3 ,dimnames=list(c("mean","sd","n"),

R memory limits on table(x, y) (and bigtabulate)
I have two character vectors x and y that have the following characteristics: length(x) # same as length(y) # 872099 length(unique(x)) # 47740 length(unique(y)) # 52478 I need to crosstabulate them, which would lead to a table with 47740*52478 # 2505299720 cells, which is more than 2^31 # 2147483648 cells, which seems to be R's limit because I am getting the error message Error in

Were to find appropriate functions for a given task in R
...his is a generic request concerning were to look for finding appropriate information on a precise procedure in R. I’m using R for teaching introductory statistics and my students are learning how to deal with it. However, I find it difficult to locate some of the procedures. For instance, for basic crosstabulation, it is obvious that basic functions as table, ftable, and prop.table can be used. But there is a CrossTable function that is very useful. This is hidden in gmodels and gregmisc, as far as I’ve been able to explore the packages. However, there is no way (unless I sit down to r-help for hours) to be...

Is there a bug in CrossTable (gmodels)
Library gmodels include a function CrossTable that is useful for crosstabulation. In the help, it is indicated that one can call this function as CrossTable(data), were data is a matrix. However, when I try to use this option, it doesn't help. Any idea? Is there a bug? Thanks for your help. Prof. Albert Sorribas Grup de Biomatem?tica i Bioestad?stica Departament de Ci?nci...

Generalising to n-dimensions
...a way of giving it every set without stating each set individually. Secondly and similarly, I want to get the table within crosstable that has the elements defined by the combinations given in expand above crosstable[,,expand[d,1],expand[d,2],expand[d,3],...expand[d,n]] where crosstable is just a crosstabulation of an n+2-dimensional dataset and I am trying to pick out those that are in combination 'd' of expand. So for example, using x[1]=2 and x[2]=3 as above example, if d =2 then the order is 2,1 so I take crosstable[,,2,1]. Can anyone suggest a way to give the code every set without stating ea...

crosstab means
I would like to obtain a crosstabulation of means(var, quantiles...) i.e. I have a data frame with Var-i, Var-j, Var-k, Var-X, var-Y I like to have the mean of Var-X for each combination of Var-i,Var-j. One solution would be: by(var-i,Var-j,mean(Var-x)) but I would like it better formatted and with mean,S.Dev,n for each cell? Does anybod...

Developmental version of Matrix package for R-1.9.0
...ustrates the performance of different ways of performing least squares calculations, using an example from Koenker and Ng's SparseM package. The results are, I think, impressive. Although not documented in this release, there are the beginnings of routines to represent large, sparse, pairwise crosstabulations as sparse matrices. I am using these in calculations for mixed-effects models and I understand that others may be interested in them for other applications. I would be happy to correspond off-list if you would like a preview of the capabilities. Metis is a package for partioning unstructured gr...
