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 makessome 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 objectdata improperly. How can data be subset as bothdata[,1:6] andd[data[,1:24]] whered =data? Fix that and your r code will work OK (syntactically at least).

• $\begingroup$Sorry, instead how I can define c1l and cl2 classes for first function so I don't have to subset data manually in second function$\endgroup$

• $\begingroup$Usegrepl on thecolnames(d) to pick relevant columns and then subset by the results of thegrepl. You should really Google this stuff.$\endgroup$

• $\begingroup$Hang on, in the first case you defined a function with 3 parameters and used just 1. What gives?$\endgroup$

• $\begingroup$Why am I getting error - the error is pretty explicit. The function is not being invoked properly.$\endgroup$
