matrix of bins with different length
Dear users, please help to define the following data structure: I would like to have a matrix, where every element is a container of different size , containing real numbers. The containers (bins) are addressed by an index pair [i,j] (i is number of corresponding row of the matrix, j is the coloumn of the matrix). The containers are initially empty, I would like to fill them

problem with package fSeries
Helo, please look at the log below: after loading the fSeries library, I can not use the log function. Is this a bug or what am I doing wrong? Because of this, I'm unable to use the garch library. thanks a lot for any help, Balazs Torma > log(1) [1] 0 > require("fSeries") Loading required package: fSeries Loading required package: robustbase Loading required package:

Counting occurances of a letter by a factor
I'm trying to find a more elegant way of doing this. What I'm trying to accomplish is to count the frequency of letters (major / minor alleles) in a string grouped by the factor levels in another column of my data frame. Ex. > DF<-data.frame(c("CC", "CC", NA, "CG", "GG", "GC"), c("L", "U", "L",

Suggestion: 'method' slot for format.ftable()
Dear R-developers, I would like to suggest a 'method' slot for format.ftable() (see an adjusted 'format.ftable()' below, taken from the source of R-2.15.2). At the moment, format.ftable() contains several empty cells due to the way the row and column labels are printed. This creates problems (= unwanted empty columns/rows) when converting an ftable to a LaTeX table; see an

Some problems with latex(ftable)
The ftable structure is not an ordinary matrix. Instead, it has the body of the table with several cbind- and rbind-ed rows and columns of label information. The example in ?ftable has two row factors and two column factors. Continuing with the example in ?ftable, enter tmp <- ftable(mtcars$cyl, mtcars$vs, mtcars$am, mtcars$gear, row.vars = c(2, 4), dnn =

Wishlist: 'append' argument for write.ftable()
I would like to suggest that an 'append' argument be added to write.ftable(). This would allow, for example, the user to append ftable() output to a text report. I have attached an svn patch to ftable.R that makes the proposed change to write.ftable(). [A very trivial change since 'append' is simply passed to cat().] I have also attached a patch to read.ftable.Rd which documents

ftable.formula
I apologize in advance if this is the wrong forum for this report/request, and for the fact that I have not read the code for ftable.formula in any detail. >From reading the documentation for ftable.formula, I expected that the following two calls to ftable would produce the same results: data(UCBAdmissions) ftable(UCBAdmissions, row.vars = "Dept", col.vars = c("Gender",

exporting ftable
How can I export an ftable object in the same format that appears in R command window? For testing that i was using this example that is in help of this function. ## Start with a contingency table. ftable(Titanic, row.vars = 1:3) ftable(Titanic, row.vars = 1:2, col.vars = "Survived") ftable(Titanic, row.vars = 2:1, col.vars = "Survived") ## Start with a data frame. x <-

How to convert an ftable object to a matrix including the row names?
Dear expeRts, What's the easiest way to convert an ftable object to a matrix such that the row names of the ftable object are shown in the first couple of columns of the matrix? This is (typically) required, for example, when the final goal is to print the matrix via xtable. Below is a rather complicated example of how to do it... Cheers, Marius ## Goal: convert an ftable() to a

Bug in ftable?? (Was: Two-way tables of data, etc)
Further to the discussion between Murray Jorgensen and Brian Ripley, it seems to me better to choose tabulations that will not come and bite you. Suppose your data are sligtly irregular, e.g. (for the sake of the argument): data( warpbreaks ) warpbreaks$variant <- rep( 1:5, len=54 ) attach( warpbreaks ) tb <- table( wool, tension, variant ) tb # in this case you would like to see: tp

ftable and xtabs
Hoping someone can help me with xtabs and ftable. I'm trying to get a pair of ftables (possibly more) next to each other. For example: > dunhill_lights_xtab<-ftable(xtabs(grossedupobs ~ gender+age_group + dunhill_lights, data = ciggs)) > dunhill_lights_xtab dunhill_lights No Yes gender age_group Female

latex of ftable (Hmisc?)
Dear latexRs, I tried to make a latex printout of a simple categorial ftable. It should look like the output of print.ftable. Any ideas how to get the syntax of summary.formula right. Or some alternative? As far I see, xtable does not have method for ftable. Dieter library(Hmisc) n=500 sex <- factor(sample(c("m","f"), n, rep=TRUE)) treatment <-

Grouped AND stacked bar charts possible in R?
Good day all, My statisticians want an R procedure that will produce grouped stacked barplots. Barplot will stack or group, but not both. The ftable function can produce a table of the exact form they want, but the barplot doesn't show all the divisions we want. For an example, here's the sample from the help file for "ftable:" data(Titanic) ftable(Titanic, row.vars = 1:3)

Scoping bug in ftable() (PR#6541)
This bug shows up in ftable() in both r-patched and r-devel: > x <- c(1,2) > y <- c(1,2) > z <- c(1,1) > ftable(z,y) y 1 2 z 1 1 1 > ftable(z,x) x 1 z 1 2 Since x and y are identical, the two ftable results should be the same, but they are not. I've only been able to see this when the column variable is named "x", so it looks like a

ftable as latex (with Hmisc?)
Dear List, possibly called Frank, I tried to create an ftable lookalike of the following data set in LaTeX/Sweave with summary(formula,..), but I could not get it to work for count tables; numeric tables work fine. summary(formula,...,fun="table") does not give the full cross breakdown. Other suggestions welcome. Note that in the output there should be empty fields on repeated

hi there tried to use subset with drop=TRUE, but all the 'old' levels are preserved, i.e. when calling e.g. ftable a lot of zeros are displayed >x<-subset(LREG, (kir=='AA' | kir=='BB') & (type=='t1' | otype=='t2'), drop=TRUE, select=c(event, kir, type)) > ftable(x) i explicit have to call factor like
