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.
