Please....... read the help and use the function properly.....
E.g.,
library(Matrix) # Since you haven't said what package you're using
show # Is a standard generic
showMethods("show") # Lots of methods available
getMethod("show", "dsyMatrix") # Get a specific method for that generic
# Turns out that in turn calls prMatrix which isn't exported so you need
getAnywhere(prMatrix)
