When I am running function as whole says that

When I am putting

and doing line by line going down after
tt[, 4] <- sqrt(tt[, 2]^4 tt[, 3]^2)
Says
Error: unexpected symbol in "tt[, 4] <- sqrt(tt[, 2]^4 tt"
I am not sure why, I put comma in

Please don't change the entire premise of the question after you get an answer. If you do, retain the original content so the post makes some sense to people.
Run ?sqrt and check how the function is to be invoked, and how you're invoking it. Does it even accept 2 input parameters?
Original Content
You are subsetting the 2D object data improperly. How can data be subset as both data[,1:6] and d[data[,1:24]] where d = data? Fix that and your r code will work OK (syntactically at least).

Usegreplon thecolnames(d)to pick relevant columns and then subset by the results of thegrepl. You should really Google this stuff.
