...nd no comparable functionality. Are there any other packages you could point me to? In general, are there efforts for replicating within one package the functionality of S+Finmetrics? Thank you very much in advance for any guidance. Best regards, _______________________ Ivan Alves mailto://papucho at mac.com

Dear all, I would like to aggregate a data frame (consisting of 2 columns - one for the bins, say factors, and one for the values) along bins and quantiles within the bins. I have tried aggregate(data.frame$values, list(bin = data.frame $bin,Quantile=cut2(data.frame$bin,g=10)),sum) but then the quantiles apply to the population as a whole and not the individual bins. Upon this

Dear all, I have been trying the following without avail and would be very grateful for any help. From a dendrogram (recursive list of lists with some structure), I would like to obtain some information of the component lists and of the enclosing list at the same time. In dendrogram-speech I basically would like the label of the leaf and the height of the enclosing branch. A dendrogram example

Dear all, List g has 2 elements > names(g) [1] "2009-10-07" "2012-02-29" and the list plot lapply(g, plot, main=names(g)) results in equal plot titles with both list names, whereas distinct titles names(g[1]) and names(g[2]) are sought. Clearly, lapply is passing 'g' in stead of consecutively passing g[1] and then g[2] to process the additional 'main'

Dear all, I searched the mail archives and the R site and found no guidance (tried "merge", "cbind" and terms like "coalesce" with no success). There surely is a way to coalesce (like in SQL) columns in a dataframe, right? For example, I would like to go from a dataframe with two columns to one with only one as follows: From Name.x Name.y nx1 ny1 nx2 NA

Dear all, Retrieving an Oracle "Date" data type by means of RODBC (version 1.2-4) I get different classes in R depending on which operating system I am in: On MacOSX I get "Date" class On Windows I get " "POSIXt" "POSIXct" class The problem is material, as converting the "POSIXt" "POSIXct" object with as.Date() returns one

Hi all, I am encountering an RODBC problem in R 2.15.1 in windows 64 bit which I do not encountered in the same set up in windows 32 bit (the latest binary version of RODBC in both cases from the same depository gotten by install.packages(‘RODBC’), Oracle ODBC client software installed in 64 and 32 bit respectively) 1. The code looks like library(RODBC) credentials <-
