将字符向量转换为 R 中的单行数据帧

Question

I have a vector that I want to turn into a single row dataframe, this code works:

vec <- c("a","b","c","d","e") 
df<- as.data.frame(t(as.data.frame(vec)))

but is so clunky, does anyone have a more elegant (and preferably less computationally expensive) solution

Answer 1

This might be one way :

data.frame(matrix(vec, 1))

#  X1 X2 X3 X4 X5
#1  a  b  c  d  e

---

Or changing your approach to this instead.

data.frame(t(vec))

Answer 2

我们也可以做

as.data.frame.list(vec)
