Quite often it is possible directly copy data by read.table("clipboard") command. No. You does not need to create **variable**. read.* function directs its output to console but you can redirect it to an **object** which is called data.frame. > visual understanding of what I am doing I attached a picture of the > head of the data. So the formula would specifically be: Battery Heat No attachments allowed (with few exceptions).

Thank you for the help I really > appreciate it. Why do.call? If variables in your data frame are named e.g. bh, sa, bt, at and your data frame name is eg. cool you can just do cool$cc <- with(cool, bh/(sa*bt-at)) to get new computed column.
