[R] How do i read the source code of "biplot"?

[R. Michael Weylandt]

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)
