In R-3.6.0 autoprinting was changed so that print methods for the storage
modes are not called when there is no explicit class attribute. E.g.,
% R-3.6.0 --vanilla --quiet
> print.function <- function(x, ...) { cat("Function with argument list ");
cat(sep="\n ", head(deparse(args(x)), -1)); invisible(x) }
> f <- function(x, ...) { sum( x * seq_along(x) ) }
> f
function(x, ...) { sum( x * seq_along(x) ) }
> print(f)
Function with argument list function (x, ...)
Previous to R-3.6.0 autoprinting did call such methods
% R-3.5.3 --vanilla --quiet
> print.function <- function(x, ...) { cat("Function with argument list ");
cat(sep="\n ", head(deparse(args(x)), -1)); invisible(x) }
> f <- function(x, ...) { sum( x * seq_along(x) ) }
> f
Function with argument list function (x, ...)
> print(f)
Function with argument list function (x, ...)
Was this intentional?
