similar to: Deleting duplicate rows in a matrix at random

Dear R-Helpers, I have a dataframe (g10df) formatted like this: GENE PVAL 1 KCTD12 4.06904e-22 2 UNC93A 9.91852e-22 3 CDKN3 1.24695e-21 4 CLEC2B 4.71759e-21 5 DAB2 1.12062e-20 The rows are ranked in ascending order by PVAL, and I need to end up with the same relative order. There are duplicate entries for genes in the first column with corresponding

Hello, I was playing around with the newly implemented 'incomparables' argument in 'match' and realized the argument does not behave anything like I expected. Can someone explain what is going on here? Sorry if I'm misreading the documentation. > match(1:3, 1:3, incomparables=1) [1] NA 2 3 # This seems right, the 1 in 'x' is 'incomparable' >

I'm doing m <- match(matriz, origen, 0) where matriz is a 270x900 matrix and origen a 11675 elements vector, and is taking a very long time. Is match a function implemented in C? If not, would a C code be faster?

Hello everyone, I have a question on isoMDS. My data set (of vegetation) with 210 samples is in this way: Rotfoehrenau Lavendelweidenau Silberweidenau .... 067_Breg.7 0 2 0 .... 071_Dona.4 0 2 6 .... ... I want to do an isoMDS-analysis with the dissimilarity index

I came across the below mis-feature/bug using match with POSIXlt objects (from strptime) in R 2.11.1 (though this appears to be an old issue). > x <- as.POSIXlt(Sys.Date()) > table <- as.POSIXlt(Sys.Date()+0:5) > length(x) [1] 1 > x %in% table # I expect TRUE [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE > match(x, table) # I expect 1 [1] NA NA NA NA NA NA NA NA

Hi, I have a data set of observations by either one person or a pair of people. I want to only keep the pair observations, and was using the code below until it gave me the error " $ operator is invalid for atomic vectors". I am just beginning to learn R, so I apologize if the code is really rough. Basically I want to keep all the rows in the data set for which the value of

Hi, I am trying to read in a rather large list of transactions using the arules library. It seems in the coerce method into the dgCmatrix, it somewhere calls unique. Unique.c throws an error when n > 536870912; however, when 4*n was modified to 2*n in 2004, the overflow protection should have changed from 2^29 to 2^30, right? If so, how would I change it in my copy? Do I have to recompile

PkgA wishes to write a method for 'unique' on S4 class 'A'. ?Methods indicates that one should setGeneric("unique") setClass("A") unique.A <- function(x, incomparables=FALSE, ...) {} setMethod(unique, "A", unique.A) Both S3 and S4 methods need to be exported in the NAMESPACE import(methods) S3method(unique, A)

To Whomever is Interested, I have spent several days searching the web, help files, the R wiki and the archives of this mailing list for a solution to this problem, but nonetheless I apologize in advance if I have missed something obvious. The problem is this; I have a 5-column data frame with about 4.2 million rows, and want to create a new (and hopefully much smaller) data frame that

Hi all, After replying to r-help earlier today on the merge() related thread, I noted a trivial grammatical error in the description for the 'suffixes' argument in it's help file. A patch against the current SVN trunk version of merge.Rd in ..library/base/man is attached and pasted here: --- merge1.Rd 2016-06-08 13:34:35.000000000 -0500 +++ merge2.Rd 2016-06-08 14:03:34.000000000

Dear all, I was playing around with factor contrasts, and found the argument nmax on function factor. When using nmax=1, R froze completely, and I had to close it from task manager. After some debugging, I found that the problem is actually in unique-function, where the internal unique function is called: .Internal(unique(x, incomparables, fromLast, nmax)) More generally, it looks like

Hi all --- this is less a specific question and more general regarding S3 classes. I've noticed that quite a few very common default implementations of generic functions (e.g. `unique`, `[`, `as.data.frame`) strip away class information. In some cases, it appears conditionals have been created to re-assign the class, but only for a few special types. For example, in `unique.default`, if the
