Delete rows where any column contains number

Finding rows containing a value (or values) in any column

Finding rows containing a value (or values) in any column

Extending on the question from the post above.

Suppose I have a dataset called m5:

set.seed(1234)
m3 <- matrix(12:1,nrow=6,ncol=4)
m4<-as.data.frame(m3)
m5 <- m4[sample(nrow(m4)),]

How do I select only rows where any column contains the value 12 or 9 or 7.

The end output should be rows 1, 2, and 6.

Also would be helpful if the proposed answer works for strings as well.

Could try:

m5[apply(m5, 1, function(x) any(x %in% c(12, 9, 7))), ]

Giving:

  V1 V2 V3 V4
4  9  3  9  3
1 12  6 12  6
6  7  1  7  1

There's also a dplyr possibility, but that may be an overkill:

dplyr::filter_all(m5, any_vars(. %in% c(12, 9, 7)))
