R 制作特定结构的矩阵

请注意：我不知道我错在哪里，但我花了一整天的时间试图解决这个问题。所以，我要求不要把它当作重复的问题，而把它当作一个与矩阵结构有关的非常具体的问题

我有以下data.frame：

dput(c.m.q)

structure(list(ASK_Price = c(1801, 1687.3, 1687.2, 1688.95, 1687.15, 
1688.95, 1687.5, 1688.85, 1689, 1688.95, 1687.5, 1688, 1688, 
1687.5, 1689.95, 1685.85, 1689.9, 1689.95, 1688.8, 1688.95, 1687.15, 
1687.2, 1690, 1688, 1688, 1690, 1688.7, 1690, 1688.7, 1689.9, 
1688.7, 1689.9, 1688.7, 1689.9, 1689.8, 1687.95, 1689.75, 1689.7, 
1687.95, 1689.35, 1689.3), BID_Price = c(1651, 1688.5, 1687, 
1688.5, 1687, 1688.5, 1687.05, 1688.5, 1687.05, 1687.05, 1688.5, 
1688.5, 1688.5, 1688.5, 1688.7, 1685.35, 1688.2, 1688.95, 1685.6, 
1685.6, 1689.05, 1685.8, 1689.1, 1686.1, 1686.25, 1689.95, 1688.05, 
1689.95, 1688.1, 1689.8, 1688.1, 1689.8, 1686.1, 1689.8, 1689.7, 
1686.15, 1689.7, 1689.15, 1686.15, 1689.15, 1689.15)), .Names = c("ASK_Price", 
"BID_Price"), row.names = c(1L, 17704L, 17707L, 17708L, 17709L, 
17710L, 17713L, 17714L, 17717L, 17720L, 17729L, 17732L, 17735L, 
17738L, 17983L, 17984L, 17985L, 17986L, 18015L, 18018L, 18029L, 
18032L, 18033L, 18223L, 18225L, 18226L, 18227L, 18228L, 18229L, 
18230L, 18231L, 18232L, 18233L, 18234L, 18235L, 18236L, 18237L, 
18238L, 18239L, 18240L, 18241L), class = "data.frame")

我希望它在结构上与此类似：

dput(mydata)

structure(c(4.56, 4.57, 4.53, 4.59, 4.55, 4.59, 4.59, 4.55, 4.55, 
4.55, 4.59, 4.55, 4.59, 4.59, 4.7, 4.64, 4.65, 4.66, 4.65, 4.66, 
4.66, 4.65, 4.65, 4.65, 4.66, 4.65, 4.66, 4.66), .Dim = c(14L, 2L))

我尝试了以下方法：

c.m.q<-as.matrix(sapply(c.m.q, as.numeric))

---

我们可以将

dimnames

转换为

matrix

后设置为NULL（假设OP文章中显示的预期输出没有任何dimnames）

@PolarBear在发布的dput中的

n_交易在哪里

，因为我不了解你提到的错误的上下文？@PolarBear，你需要问你真正的问题，而不是你认为能为你解决真正问题的其他问题。
