我有這個data.frame
:基於R轉換data.frame簡單的矢量
> print(v.row)
X1 X2 X3 X4 X5 X6 X7 X8 X9 X10 X11 X12 X13 X14 X15 X16 X17 X18 X19 X20 X21 X22 X23 X24
57 177 165 177 177 177 177 145 132 126 132 132 132 126 120 145 167 167 167 167 165 177 177 177 177
> dput(v.row)
structure(list(X1 = 177, X2 = 165, X3 = 177, X4 = 177, X5 = 177,
X6 = 177, X7 = 145, X8 = 132, X9 = 126, X10 = 132, X11 = 132,
X12 = 132, X13 = 126, X14 = 120, X15 = 145, X16 = 167, X17 = 167,
X18 = 167, X19 = 167, X20 = 165, X21 = 177, X22 = 177, X23 = 177,
X24 = 177), .Names = c("X1", "X2", "X3", "X4", "X5", "X6",
"X7", "X8", "X9", "X10", "X11", "X12", "X13", "X14", "X15", "X16",
"X17", "X18", "X19", "X20", "X21", "X22", "X23", "X24"), row.names = 57L, class = "data.frame")
我會刪除爲了得到一個簡單的vector
所有的行和列名。但as.vector
函數不起作用(它返回data.frame
)。

as.vector(v.row,mode ='numeric')爲我工作。 – 2017-07-07 08:42:09
