write.csv(mydata, file= “data.csv”=F, append=T) . the csv file looks
fine
but I always get the following warning message
Warning messages:

Does anyone see why R print out this warning message?
Have you looked at the help page for write.csv? The answer rather
leaps out of the page at you. It's telling you that mixed in with
your data will be a bunch of column names.
