基于R中多个参数的数据帧行数

我希望根据多个参数查找行号。我制作了这个测试矩阵：

data=
     [,1] [,2] [,3]
[1,] "1"  "a"  "0" 
[2,] "2"  "b"  "0" 
[3,] "3"  "c"  "0" 
[4,] "4"  "a"  "0" 
[5,] "1"  "b"  "0" 
[6,] "2"  "c"  "0" 
[7,] "3"  "a"  "0" 
[8,] "4"  "b"  "0" 

然后我想得到行号在哪里

data[,1]==1 and data[,2]=='b'

which（数据[，1]=“1”）

和

which（数据[，2]=“b”）

which（（数据[，1]=“1”）和（数据[，2]=“b”）
