[R] Extracting data using subset function

[Upananda Pani]

Dear All,

I want to create a vector p and extract first 20 observations using subset
function based on logical condition.

My code is below

p <- 0:100

I know i can extract the first 20 observations using the following command.

q <- p[1:20]

But I want to extract the first 20 observations using subset function which
requires a logical condition. I am not able to frame the logical condition.

The code should be

q <- subset(p, logical condition)

I am not able to do it. Please let me know what you think.

Best regards,
Upananda
