R 从多个向量生成布尔型矩阵

假定

---

尝试

表格

和

堆栈

：

xx.1 xx.2 xx.3
a    1    1   NA
b    1   NA    1
d    1    1    1
e   NA    1    1
f   NA   NA    1

更方便的是，您可以尝试：

table(stack(list(xx.1 = xx.1, xx.2 = xx.2, xx.3 = xx.3)))
#       ind
# values xx.1 xx.2 xx.3
#      a    1    1    0
#      b    1    0    1
#      d    1    1    1
#      e    0    1    1
#      f    0    0    1

table(stack(list(xx.1 = xx.1, xx.2 = xx.2, xx.3 = xx.3)))
#       ind
# values xx.1 xx.2 xx.3
#      a    1    1    0
#      b    1    0    1
#      d    1    1    1
#      e    0    1    1
#      f    0    0    1

table(stack(mget(ls(pattern = "xx"))))
