You seem to have collapsed the two columns of data into a single column.
That's why it works for you.

The OP should use the dput function to show the data.
If I take the data as presented I get the same error (but I don't use sep="," since the data displayed don't contain a ,).
And show the actual code used such as library(MASS).
