我转换了数据框，但找不到提取第一行的行名的方法（在我的示例中为“颜色”）：
df <- read.table(text = " color birds wolfs
red 9 7
red 8 4
red 2 8
red 2 3
black 8 3
black 1 2
black 7 16
black 1 5
black 17 7
black 8 7
black 2 7
green 20 3
green 6 3
green 1 1
green 3 11
green 30 1 ",header = TRUE)
df_t<-t(df)
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12] [,13] [,14] [,15] [,16]
color "red" "red" "red" "red" "black" "black" "black" "black" "black" "black" "black" "green" "green" "green" "green" "green"
birds " 9" " 8" " 2" " 2" " 8" " 1" " 7" " 1" "17" " 8" " 2" "20" " 6" " 1" " 3" "30"
wolfs " 7" " 4" " 8" " 3" " 3" " 2" "16" " 5" " 7" " 7" " 7" " 3" " 3" " 1" "11" " 1"
如果使用：df_t[1,1]我得到：
color
"red"
如何只提取字符串“ color”并保存。
在您的示例中"color"是行名称之一。尝试rownames(df_t)[1]
