How to combine multiple conditions to subset a data-frame using "OR"?

Question

I have a data.frame in R. I want to try two different conditions on two different columns, but I want these conditions to be inclusive. Therefore, I would like to use "OR" to combine the conditions. I have used the following syntax before with lot of success when I wanted to use the "AND" condition. my.data.frame <- data[(data$V1 > 2) & (data$V2 < 4), ]But I don't know how to use an 'OR' in the above.

Answer 1

The "OR" operator in R is the bar symbol (|). So, your code should be something like the following:

```

my.data.frame <- data[(data$V1 > 2) | (data$V2 < 4), ]

# Alternative approach with subset()

my.data.frame <- subset(data, V1 > 2 | V2 < 4)

```

Hope this helps!
