I recently changed to Mac OS X 10.7.3 from Windows and this simple function
is giving errors.

> c(4,7,7)
Error in c(4, 7, 7) : unused argument(s) (7)

> c(1,7:9)

Error in d[i, ] : incorrect number of dimensions


> c(1:5, 10.5, "next")
Error in c(1:5, 10.5, "next") : unused argument(s) ("next")

> c(1,2)

Error in d[i, ] : incorrect number of dimensions



I removed R and reinstalled, but I get the same problem.

Could you please help?


Thank you.
