Presuming "data" is a data frame because you have not provided a minimal reproducible example as requested in the Posting Guide... note also that "data" is the name of a function in base R, so that is a potentially troublesome variable name. 

 A data frame is a list of vectors. It can be indexed either as a one-dimensional object of length equal to the number of columns, or as a two-dimensional object. You are doing the former but giving a logical index appropriate for the number of rows in your data frame. Go re-read the Introduction to R document section on indexing to figure out where the comma goes.
