Dear List, Is there a way I can sort a sample based on a sort index constructed from the data from which the sample is taken? Basically, I need to take '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...

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::Sor...

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.

Hi I think this is a very easy question but here goes: I want to sort 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 so...

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...

Hi, while backtracking why sort(NULL) gives a warning, and acknowledging that NULL is not the same as an empty vector and sort(NULL) is bad coding, I discovered the following inconsistency of sort.int(): > x <- NULL > sort(x) Warning in is.na(x) : is.na() applied to non-(list or vector) of type 'NULL' NULL &...

I have a library I''ve developed that I believe is the most flexible and useful table sorting/striping/row-selecting library around. Big features: Single and multiple-level sort Arbitrary sort criteria (IP address, date, etc.) Works with table headers that are > 1 row or column large Stripe tables and/or enable row selecting Row selecting supports drag-select and SHIFT-click No extra...

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=>{:b...

Hi, Consider the following example: sort(10:1, partial=3) ## 1 2 3 7 6 5 4 8 9 10 sort(10:1, index=T) ## $x: 1 2 3 4 5 6 7 8 9 10 ## $ix: 10 9 8 7 6 5 4 3 2 1 sort(10:1, partial=3, index=T) ## 1 2 3 7 6 5 4 8 9 10 The first 2 calls gave expected returns; however, the third one did not returned an index...

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-for...

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...

Dear all This may be obvious, but I cannot get it working. I'm trying to subset & sort a data frame in one go. x <- iris x$Species1 <- as.character(x$Species) ##subsetting alone works fine with(x, x[Sepal.Length==6.7,]) ##sorting alone works fine with(x, x[order(Sepal.Length, rev(sort(Species1))),]) ##gets subsetted, but not sorted as expected with(x, x[(Sepal.Length==6.7) &amp...

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?" For example > modelincr10<-lme(lruin~can.pos.num, data=rwushi30, random=(~1| site/transect/plot),na.action=na.omit) > summary(modelincr10) > qqnor...

Oh, this seemed so simple (and I'm sure the answer will be, as usual, so thanks in advance for enlightening me). I need to sort each row of a matrix independent of the others. For example, > test <- matrix(c(8,7,1,2,6,5,9,4,3),nrow=3) > test [,1] [,2] [,3] [1,] 8 2 9 [2,] 7 6 4 [3,] 1 5 3 I can get each row sorted well enough. > sort(test[1,]) [1] 2 8 9 > sort(test[2,]) [1]...

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 sort...

I am trying to sort 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 sor...

...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. Thank...
