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

[Murray Jorgensen]

Dear R list,

members of my course have encountered the following error message:

> slm <- lm(price ~ engsize, autoframe)
Error in get(x, envir, mode, inherits) : variable "FUN" was not found
[more context is given in the fuller listing below].

Once the error is encountered it seems to persist; for example early in one
session:

> summary(blin.fit)

Call:
lm(formula = Response ~ Row + Column, data = binframe)

Residuals:
       Min         1Q     Median         3Q        Max 
-1.417e+00 -5.833e-01 -4.025e-16  6.042e-01  1.083e+00

Multiple R-Squared: 0.9717,     Adjusted R-squared: 0.9482 
F-statistic: 41.27 on 5 and 6 degrees of freedom,       p-value: 0.0001434 


but later on, after the error in creating slm:
> summary(blin.fit)

Call:
lm(formula = Response ~ Row + Column, data = binframe)

Residuals:
Error in get(x, envir, mode, inherits) : variable "FUN" was not found



Finally, here are the commands and output leading up to the first instance
of the error:  [any help greatly appreciated!]
