What is probably going wrong is that Pat2006 and FHouse are part of a data.frame, as columns. If the columns are in the same data.frame, say one called df:
mod1 <- lm(Path2006 ~ FHouse, data = df) an alternative is to use assign to dump the columns as variables in your workspace: > speed Error: object 'speed' not found > attach(cars) > speed [1] 4 4 7 7 8 9 10 10 10 11 11 12 12 12 12 13 13 13 13 14 14 14 14 15 15 [26] 15 16 16 17 17 17 18 18 18 18 19 19 19 20 20 20 20 20 22 23 24 24 24 24 25 but I am very much in favor of the first solution using "data =". Using attach fills up your workspace with a great deal of objects. Keeping the columns in a data.frame is also better from a design point of view: having them in one data.frame already groups together variables (columns) that share a common background.
