showDefault has
clDef <- getClass(class(object))
Looks like the showDefault code intended
clDef <- getClass(class(object), .force=TRUE)
However, why are you calling show() on a non-S4 object? I cannot see any
advtanges in doing so.

Dear List,
Calling "show" on an object of class "summary.lm" gives:
Error in getClass(class(object)) : "summary.lm" is not a defined class
Is this a miss on my end ?
x <- seq(1, 10)
show(x)
[1] 1 2 3 4 5 6 7 8 9 10
y <- runif(10)
fit <- lm(y ~ x)
show(fit)
Call:
lm(formula = y ~ x)
Coefficients:
(Intercept) x
1.04938 -0.08869
show(summary(fit))

class(summary(fit))
[1] "summary.lm"
class((fit))
