For some clever reason, write.csv won't let you set col.names argument to FALSE, but you can use it with write.table using sep=",".
A self-contained, minimal, and working example: write.csv(matrix(1:10,2,5), "test.csv") write.table(matrix(11:20,2,5), "test.csv", sep=",", append=TRUE, col.names=FALSE) Regards, KK On Mon, Feb 9, 2009 at 12:17 PM, venkata kirankumar <kiran4u2...@gmail.com>wrote: > Hi all, > I am new to R-project > I have a problem when when ever I am going to append a row in a *.csv file > that is > in R-project I created one dataframe and I saved it in "res.csv" and again > I got some results in dataframe with same column names and i tried to > append > in a new row of same "res.csv" file but its appending again with > columnnaes like > > > > first time when i created the csv file > > "","max","min","avg" > "1",22,7,12.9833333333333 > > and when I try to append another column for this file its writing like > > "","max","min","avg" > "1",22,7,12.9833333333333 > "","max","min","avg" > "1",19,7,12.9918699186992 > > > can any one suggest how to solve this problem > and how can I save new rows without taking column names > > > and also i tried with "append()" function to append to dataframes then > also its giving the same result > > thanks in advance > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
