[程式] [R]計算配對後相關係數的對數
------------------------------------------------------------------------
[軟體程式類別]:R
[程式問題]:假設Raw data在不同變項尚有缺漏值，今計算相關係數矩陣，如何得知
配對成幾對?
[軟體熟悉度]:高(1年以上)
[問題敘述]:如前所述
[程式範例]:
mydata=matrix( c(1,2,NA,4,5,NA,7,8,9,10), 5,2)
cor(mydata,use="pairwise")
[,1] [,2]
[1,] 1 NA
[2,] 2 7
[3,] NA 8
[4,] 4 9
[5,] 5 10
由範例可知,應可配對成三對,但R的cor指令僅會輸出相關矩陣結果,並不會像SPSS
一樣可輸出N或SD，有無相關指令可以查詢?
謝謝R前輩協助解惑!
