Hello, I am using R 1.9.1 on Windows 2000 SP4. I have the following problem: Say I have a matrix, >my.matrix [,1] [,2] [,3] [1,] "A" "B" "C" [2,] "D" "E" "F" [3,] "G" "H" "I" I would like to apply an operation to this matrix which returns a list my.list containing the

Hello, I'm not sure how to state my question in a technically accurate manner, so I'll use a short example to clarify my problem: Say I have a vector, vec<-c(1,2,3,2) I would like to be able to "reference" the vector by using the string containing the name of the vector - that is, I would like to know of some function which is able to convert the string "vec"

Hello, I am running R 1.9.1 om Windows 2000 SP4. My problem is as follows: Say I have a dataframe my.frame with column names A and B. I have a string, >my.string [1] "A==1 & B==2" And I would like to retrieve the subset corresponding to my.string, that is, from my.frame and my.string I would like to get the result of subset(my.frame,A==1 & B==2) So I need to find a way

Hello, I have two vectors of different lengths. Fx a <- 1:9; b <- c(4, 5). What is the best way to remove the elements in vector b from vector a so that the result would be a vector with elements c(1,2,3,6,7,8,9)?

Hi, I am struggling, I have 2 lists with shared elements, one ~600, one ~1000, and I need to determine the difference between them. They are character strings, and to use setdiff(), or unique() I need vectors. I don't know how to force these character strings into a form where you can use functions like setdiff(). Any help would be greatly appreciated. > head(R1) [1]

Dear R-list, I have a problem which I think is quite basic, but so far google has not helped me. I have two vectors like this: vector_1 <- c(Belgium, Spain, Greece, Ireland, Luxembourg, Netherlands, Portugal) vector_2 <- c(Denmark, Luxembourg) I would like to find the elements in vector_1 that are not in vector_2 so that i get a vector with these countries: Belgium, Spain, Greece,

Hi all, I have some rough code to sample consecutive integers with length according to a vector of lengths #sample space (representing positions) pos<-c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20) #sample lengths lengths<-c(2,3,2) From these two vectors I need a vector of sampled positions. the sampling is without replacement, making things tough as the sampled integers need

Sorry, maybe it's easy but I haven't found anything useful: how can I obtain a list C that contains all the members in the list B that are not in list A? This are lists of nanes, not numbers!

Hi, I have a matrix with two columns, and the elements of the matrix are vectors. So for example, in line 3 of column 1 I have a vector v31=("marc", "robert, "marie"). What I need to do is to compare all vectors in column 1 and 2, so as to get, for example setdiff(v31,v32) into a new column. Is there a way to do this in R? Thanks! -- View this message in context:

First, let me apologize in advance if this is the wrong place to submit a suggestion for a change to functions in the base-R package. It never really occurred to me that I'd have an idea worthy of such a change. My idea is to provide an upgrade to all the "sets" tools (intersect, union, setdiff, setequal) that allows the user to apply them in a strictly algebraic style. The

Dear R-devel, Please see the recent thread on R-help, "Odd Behavior Out of setdiff(...) - addition of duplicate entries is not identified" posted by Jason Rupert. I gave an answer, then read David Winsemius' answer, and then did some follow-up investigation. I would like to change my answer. My current version of setdiff() is acting in a way that I do not understand, and a way

Hi all, I expect I'm getting something wrong, but cat("foo bar baz foo bar baz foo bar baz", fill = 10) should be broken into lines of width 10, whereas I get: > cat("foo bar baz foo bar baz foo bar baz", fill = 10) foo bar baz foo bar baz foo bar baz This is on R 3.4.3, but I don't see mentions of it fixed in 3.4.4 or r-devel NEWS.

Hello group, I am learning R and I am new to many concepts.I face the following errors when I am trying to execute the following. I have 4 text files with protein accession numbers. I wanted to represent them in a venn diagram and for that I using intersect and setdiff functions.

Hi list, just for my appreciation: can I plug two harddisks already setting up with lvm into several boxes without losing my logical volume? Cheers, Kamill

I think I am using the improved version of setdiff(...) that handles data.frames, so I think some odd behavior was expected but this one is escaping me. It appears that the the addition of duplicate entries is not caught by the setdiff(...). Is this expected behavior? If so, is there another method or approach that should be used to identify duplicate row entries between two different data

Dear All: I would like to know if there is plausible way to say to R to remove all elements in the memory but the sequence. I have a code which makes a loop, and what I want is after the programme has performed all the operation over every "i"th element, to remove all the objects, expect the sequence parameter. I included the option "rm(list=ls(all=TRUE))", but obviously that
