Hi there,

I would like to write a data output. In first time, a data frame (called "res") is written in a file *csv such as:

A B C # names of data
1.5 4.5 7 # values

So I use "write.table" which prints "res" to a file "file.csv" write.table(res,file="file.csv",sep="",row.names=TRUE,col.names=TRUE,eol
= "\n")

After, I would like to append other data to the same file,

A B C
1.5 4.5 7
3 6 9 # appended data

I use then the same function but with different arguments: write.table(res,file="file.csv",append=TRUE,sep="",row.names=TRUE,col.names=FALSE,eol
= "\n")

Actually, it doesn't work, the file is overwritten by the new one.

I got something like that:
A B C
3 6 9

Coul you help me? Thank you in advance

Kind regards,
Marie-NoŽlle
