search for: sorted

...'many' samples from the same source data and sort them. This can be very time consuming for long vectors. Is there any way I can sort the data only once initially, and use that sort order for the samples? I believe that idea is what is implemented in tree-based classifiers, so the data is sorted only once initially and that sort order is used for the child nodes. set.seed(12345) x <- sample(0:100, 10) x.order <- order(x) x.sorted <- x[x.order] sample.ind <- sample(1:length(x), 5, replace = TRUE) #sample 1/2 size with replacement x.sample <- x[sample.ind] x.sample.sorted...

I''m trying to sort my search results by Date, in descending order. I''ve done quite a bit of reading through the forums here, and I''ve tried two different suggestions. This just returns results in the same order as a search without a sort: sort_fields = [] sort_fields << Ferret::Search::SortField.new("ferret_created_at",:reverse => :true)

Is there a R function for sort a data frame by a variable ? I know sort a vector, but I don't know sort a data frame by a column. Can you help me ? the sort() function don't work with data frame.

...rt my results by a boolean field and then by score, I thought this would be a default configuration but apparently not. sort_fields = [] sort_fields << Ferret::Search::SortField.new(:sponsored, :reverse => :true) that is my current code, how do iu alter it so that the results are then sorted by highest score first? thanks very much. regards caspar -- Posted via http://www.ruby-forum.com/.

Hello, I wonder if I ran into a bug. If I do summary(df1$X1) -> df1.y df1.y a b c d e [1,] 50.74627 8.955224 17.91045 19.40299 2.985075 sort(df1.y) a b c d e [1,] 2.985075 8.955224 17.91045 19.40299 50.74627 my numbers are sorted but do not anymore correspond to the rownames. For me it is counterintuitive that solely the numbers are sorted and not the names. Is there a way to sort names + numbers or is this behaviour of sort() unintended? Martin R 2.0.1-1 debian reposit.

...(list or vector) of type 'NULL' Error in sort.list(x, decreasing = decreasing) : argument 1 is not a vector > sort.int(x, partial=1) Warning in is.na(x) : is.na() applied to non-(list or vector) of type 'NULL' Error in sort.int(NULL, partial = 1) : only atomic vectors can be sorted > order(x) Error in order(x) : argument 1 is not a vector Using an empty vector behaves correctly, e.g. x <- character(0). For consistency, should sort.int(NULL) also give an error? If so, that would result in sort(NULL) throwing an error too, which might have lots of implications to cod...

...port (AFAIK) All the other table-sorting libraries I''ve found try to "guess" what they''re sorting. This library makes no attempt to do so, instead assuming the designer can tell it how to sort by giving it a function for each sortable column that returns a value to be sorted. An example: ----------------- <table id="myTable" class="sortable striped rowsSelectable"> <thead><tr><th>string</th><th>number</th><th>date</th></tr></thead> <tfoot /> <tbody> .......... </tbody...

I''m having problems sorting on untokenized fields. I have one field that sorts fine, but there are others that seem to sort on a different field. Here''s the index description: acts_as_ferret :remote=>true,:fields=>{:name=>{:boost=>2},:name_for_sort=>{:index => :untokenized}, :city=>{:boost=>2}, :city_for_sort=>{:index=>:untokenized},

Hello All, I am having an issue with AAF and sorting results of a search. Right now, I have results being split onto pages of 10. The results are being sorted alphabetically, but not across multiple pages - it''s just sorting the 10 it pulls down on each page. I noticed another post from April regarding this same issue (http://www.ruby-forum.com/topic/62993#66934) where the issue was claimed to be resolved - so I figure I''m doing somethi...

I was looking at rank() and I came across: ... "first" = sort.list(sort.list(xx)), ... line 32 of rank.r [1] sort.list(x) returns the indices of the values of x in ascending (by default) order. So sort.list(sort.list(x)) returns the same list. So, what am I missing here? -Tyler [1] view-source:http://svn.r-project.org/R/trunk/src/library/base/R/rank.R [[alternative HTML version

Hi all, I'm modeling using lme in the nlme package. qqnorm makes plots just find, but when I try to add a line with qqline, I get the following error: "Error in sort.list(x, partial = unique(c(lo, hi))) : 'x' must be atomic for 'sort.list' Have you called 'sort' on a list?"

Hi, I'm trying to translate some Matlab code to R and I'm trying to implement the behavior of Matlab's sort() which when applied to a matrix will sort the columns returning the column sorted matrix as well as a matrix of permuted indices. Doing: > x <- matrix(c(3,4,2,6,3,4,8,7,5), nr=3) > x [,1] [,2] [,3] [1,] 3 6 8 [2,] 4 3 7 [3,] 2 4 5 What I want after sorting x are two matrices: (the column sorted x) 2 3 5 3 4 7 4 6 8 and (the index mat...

...ort a list and the data is obiously not in the right format. I am trying: x <- list() x[["A"]] <- 1 x[["B"]] <- 2 order(x) But am getting: Error in order(x) : unimplemented type 'list' in 'orderVector1' How should I change the list so that it can be sorted? What kinds of objects (classes of objects) can be sorted? Thank you. Kevin

...e use of an id parameter for an event history/survival model, and why the EHA documentation for aftreg does not specify one. All assistance and insights are appreciated. Attempting to specifiy an id variable with the documentation example generates an "overlapping intervals" error, so I sorted the original mort dataframe and set subsequent entry times an id to the previous exit time + 0.0001. This allowed me to see the affect of the id parameter on the coefficients and significance tests, and prompted my question. The code I used is shown below, with the results at the bottom. Thanks...
