almost certainly you restored an old workspace with a conflicting
definition of the c function.

type

c

to confirm,

also type

conflicts(detail=TRUE)

The repair is to remove the conflicting definition

rm(c)


The long term solution is to adopt the recommended practice of not saving
your workspace at
the end of an R session.  When R asks about saving when you type q(), say
no.

You can get rid of the .RData you have by finding out what directory it is
in with
getwd()

and then closing R and removing the .RData from outside R.
