Hi farzana, Probably the first thing is to ascertain what the class of "farzana" might be:
class(farzana) Because "write.csv" expects "the object to be written, preferably a matrix or data frame. If not, it is attempted to coerce x to a data frame." to be the first argument. It seems that "farzana" is neither a matrix nor a data frame and something for which there is no method to convert it to one. The second thing to do is to try to work out what is inside "farzana": str(farzana) This will produce a summary of what is in there. _Maybe_ with that summary you can figure out how to convert it into a data frame. If not, you can always save the object: save(farzana,file="farzana.Rdata") and reload it later.
