Re: [R] remove repeated string in list

Hi, Here is one for removing repeated strings. > temp $set1 [1] "a" "b" "d" "x" $set2 [1] "b" "c" "q" "m" $set3 [1] "b" "f" "e" "k" "q" "h" > sapply(1:3,function(x){temp[[x]][as.numeric(table(unlist(temp))[temp[[x]]])==1]}) [[1]] [1] "a" "d" "x" [[2]] [1] "c" "m" [[3]] [1] "f" "e" "k" "h"

Re: [R] remove repeated string in list

Hi, Here is one for preserving the first strings. as.numeric in the previous posting is not necessary. > temp $set1 [1] "a" "b" "d" "x" $set2 [1] "b" "c" "q" "m" $set3 [1] "b" "f" "e" "k" "q" "h" > sapply(1:length(temp),function(x){c <- list(); for (j in 1:x){c <- > c(c,temp[[j]])}; temp[[x

Re: [R] remove repeated string in list

Hi, To avoid hardcoded 1:3, here is some revision. > temp $set1 [1] "a" "b" "d" "x" $set2 [1] "b" "c" "q" "m" $set3 [1] "b" "f" "e" "k" "q" "h" > sapply(1:*length(temp)*,function(x){temp[[x]][as.numeric(table(unlist(temp))[temp[[x]]])==1]}) [[1]] [1] "a" "d" "x" [[2]] [1] "c" "m" [[3]] [1]

[R] remove repeated string in list

Dear All, here an example temp <- list(set1=c("a","b","d","x"), set2=c("b","c","q","m"), set3=c("b","f","e","k","q","h")) preserve only the first one string >temp set1 a b d x set2 c q m set3 f e k h OR remove repeated string >temp set1 a d x set2 c m set3 f e k h Thanks [[alternativ
