as.matrix（）とas.dist（）が異なる結果

Question

を持っている私は、7つのベクトルを含むリスト「simil」、持っている：

> dput(simil) 
structure(list(Monday = structure(c(0.889987253484581, 0.882957894295089, 
0.882232353177177, 0.874080268021168, 0.851760771472629, 0.811536071048775 
), .Names = c("Sunday", "Tuesday", "Friday", "Wednesday", "Thursday", 
"Saturday")), Tuesday = structure(c(0.901682757072732, 0.882957894295089, 
0.874716806575548, 0.869202937572079, 0.855248496101086, 0.818659253763272 
), .Names = c("Sunday", "Monday", "Wednesday", "Friday", "Thursday", 
"Saturday")), Wednesday = structure(c(0.88354911311872, 0.874716806575548, 
0.874080268021168, 0.853293126413937, 0.851921112754124, 0.841170795359615 
), .Names = c("Sunday", "Tuesday", "Monday", "Friday", "Thursday", 
"Saturday")), Thursday = structure(c(0.86579834238668, 0.855248496101086, 
0.851921112754124, 0.851760771472629, 0.851384896045153, 0.836732564057725 
), .Names = c("Sunday", "Tuesday", "Wednesday", "Monday", "Friday", 
"Saturday")), Friday = structure(c(0.882232353177177, 0.869202937572079, 
0.856441568566172, 0.853293126413937, 0.851384896045153, 0.80098779448239 
), .Names = c("Monday", "Tuesday", "Sunday", "Wednesday", "Thursday", 
"Saturday")), Saturday = structure(c(0.866654844262859, 0.841170795359615, 
0.836732564057725, 0.818659253763272, 0.811536071048775, 0.80098779448239 
), .Names = c("Sunday", "Wednesday", "Thursday", "Tuesday", "Monday", 
"Friday")), Sunday = structure(c(0.901682757072732, 0.889987253484581, 
0.88354911311872, 0.866654844262859, 0.86579834238668, 0.856441568566172 
), .Names = c("Tuesday", "Monday", "Wednesday", "Saturday", "Thursday", 
"Friday"))), .Names = c("Monday", "Tuesday", "Wednesday", "Thursday", 
"Friday", "Saturday", "Sunday"), class = c("similMatrix", "list" 
)) 

を私は今、次に使用するdistのオブジェクトに変換したいですそれはhclust（）のためです。だから私はas.dist（）を使用して、私は計算：

> as.dist(simil,diag = TRUE, upper = TRUE) 
      Monday Sunday Tuesday Friday Wednesday Thursday Saturday 
Monday 0.0000000 0.8899873 0.8829579 0.8822324 0.8740803 0.8517608 0.8115361 
Sunday 0.8899873 0.0000000 1.0000000 0.8692029 0.8747168 0.8552485 0.8186593 
Tuesday 0.8829579 1.0000000 0.0000000 0.8532931 1.0000000 0.8519211 0.8411708 
Friday 0.8822324 0.8692029 0.8532931 0.0000000 0.8519211 1.0000000 0.8367326 
Wednesday 0.8740803 0.8747168 1.0000000 0.8519211 0.0000000 0.8513849 0.8009878 
Thursday 0.8517608 0.8552485 0.8519211 1.0000000 0.8513849 0.0000000 1.0000000 
Saturday 0.8115361 0.8186593 0.8411708 0.8367326 0.8009878 1.0000000 0.0000000 

しかし、これは私がas.matrix（）を使用する場合とは若干異なる結果である：as.dist()で

> as.matrix(simil) 
      Monday Tuesday Wednesday Thursday Friday Saturday Sunday 
Monday 1.0000000 0.8829579 0.8740803 0.8517608 0.8822324 0.8115361 0.8899873 
Sunday 0.8899873 0.9016828 0.8835491 0.8657983 0.8564416 0.8666548 1.0000000 
Tuesday 0.8829579 1.0000000 0.8747168 0.8552485 0.8692029 0.8186593 0.9016828 
Friday 0.8822324 0.8692029 0.8532931 0.8513849 1.0000000 0.8009878 0.8564416 
Wednesday 0.8740803 0.8747168 1.0000000 0.8519211 0.8532931 0.8411708 0.8835491 
Thursday 0.8517608 0.8552485 0.8519211 1.0000000 0.8513849 0.8367326 0.8657983 
Saturday 0.8115361 0.8186593 0.8411708 0.8367326 0.8009878 1.0000000 0.8666548 

を、マトリックスではありません完全に対称であり、いくつかのペアは間違っています。これはas.matrix()では起こりません。何故ですか？どうすれば修正できますか？

Answer 1

だから最後に私は、行の順序をswaping、第1のマトリックスに変換することによってそれを修正するために管理され、最終的にはdistのオブジェクトに変更：

simil = as.matrix(simil) 
simil = simil[ c(1,3,5,6,4,7,2),] 
simil = as.dist(1-simil,diag = TRUE, upper = TRUE) 

> simil 
       Monday Tuesday Wednesday Thursday  Friday Saturday  Sunday 
Monday 0.00000000 0.11704211 0.12591973 0.14823923 0.11776765 0.18846393 0.11001275

それは「その事実によるかもしれませんsimil "はquantedaパッケージのsimilarity（）関数から作成されました。
