R keep rows with at least one column greater than value

问题

Say I have a data frame with a few hundred rows and a few hundred columns. How would I keep rows that have at least one value greater than 10?

回答1:

You can use rowSums to construct the condition in base R:

df[rowSums(df > 10) >= 1, ]

---

with dplyr (0.7.0), now you can use filter_all like this:

library(dplyr)
filter_all(df, any_vars(. > 10))

回答2:

This is another option:

df[apply(df>10,1,any),]

回答3:

We can use lapply with Reduce

df[Reduce(`|`, lapply(df, `>`, 10)), ]

data

set.seed(24)
df <- as.data.frame(matrix(sample(1:12, 5*20, replace=TRUE), ncol=5))
