[R] Error in get(x, envir, mode, inherits)

[Murray Jorgensen]

I have reproduced the error with a smaller set of commands and a smaller
data file on two PCs under both 0.64.1 and 0.64.2.

I have not reproduced it with an inbuilt data set (except where it has
previously occured with my problem data.)

> autoframe <- read.table("f:/maj/R&Splus/auto2.txt", header=T)
> attach(autoframe)
> slm <- lm(price ~ engsize, autoframe)
Error in get(x, envir, mode, inherits) : variable "FUN" was not found

I venture to include the dataset auto2.dat as it is not overly large:
