[R] write.csv with append = TRUE

[Alex van der Spek]

Is there a way to make any of the write functions (.table or .csv) append
to the same file?

I get this warning message and do not know how to enable the appending.

Warning messages:
1: In write.csv(names(Lbys)[c], fo, append = TRUE) :
  attempt to set 'append' ignored
2: In write.csv(Lbys[[c]], fo, append = TRUE) :
  attempt to set 'append' ignored
