I may be being dopey, I surely am, but I'm baffled by this. I've been working, on and off for a few days in R version 2.13.0 (2011-04-13) i386-pc-mingw32/i386 (32-bit) working it through ESS. I've got a dataframe created a couple of days back, during the session: > dim(AllDat) [1] 27270 94 I came back this morning and misremembered my variables and thought I had a variable AllDat$PHQ and started using it and everything seemed fine until I realised that I shouldn't have it (!) and that the variable I was thinking of is AllDat$PHQ9 and that's there: > colna...

Hi All! I have been messing around with this problem for about a week but to no avail! The following data has been cut down in order to make my question reproducible. The alldat data frame includes 2 columns: 1 date column and 1 factor column (equity names)). mydate<-as.Date(c("2001-07-02","2001-07-02","2001-07-03","2001-07-03","2001-07-05","2001-07-05","2001-07-10","2001-07-13","2010-...

Hello. I'm using as.ffdf(mydataframe) to create ffdf objects inside an lapply loop and returning that. I then use crbind to combine the lapply results into allData. So...simplified flow looks like this. res <- lapply(1:nchunks, function(n) { blah blah with nth chunk mydataframe <- data.frame(blah blah) dat <- as.ffdf(mydataframe) return(dat) }) allDat <- do.cal...

Hi, I am doing PCA on several columns of data in a data.frame. I am interested in particular rows of data which may have a particular combination of 'types' of column values (without any pre-conception of what they may be). I do the following... # My data table. allDat <- read.table("big_select_thresh_5", header=1) # Where some rows look like this... # PDB SUNID1 SUNID2 AA CH IPCA PCA IBB BB # 3sdh 14984 14985 6 10 24 24 93 116 # 3hbi 14986 14987 6 10 20 22 94...

I use the following code in my view: <%= collection_select(''datedata'', ''date'', @allDate, :id, :date) %> It''s show me the date of all entries in the database (Dropdown menu). Additional, I wrote a helper method "showDate" in the application_helper.rb! How can I use this method in the collection_select for every date entry? thanks for your anwser! -- Posted...
