将表更改为不带空格的字符向量

Question

我们有以下数据:

df <- data.frame(c("a", "c ","e "), c("b ", "d", "f "))
colnames(df) <- c("X1", "X2")
df
  X1 X2
1  a b 
2 c   d
3 e  f

如何将给定的data.frame转换为一个没有空格的字符向量？

#Expected result:
#vector
#[1]"abcdef"

Answer 1

来自基地R的另一个解

paste(trimws(as.vector(t(df))), collapse = "")
# [1] "abcdef"
