What can I do to fix this?
Read ?write.csv more carefully: In the "CSV files" section: These wrappers are deliberately inflexible: they are designed to ensure that the correct conventions are used to write a valid file. Attempts to change append, col.names, sep, dec or qmethod are ignored, with a warning. If you want to use 'append', you will need to use write.table() and adjust the other arguments as you require.
