[R] Column of numbers added to dataframe when saving with read.csv
I have a dataframe object having the following structure
FinalOutput[1:3,]
GasDays 2011-03-31 2010-09-30 2010-10-31 2010-11-30 2010-12-31
2011-01-31 2011-02-28
1 2006-10-01 217303553 221205033 222824639 217016511 216093460
216477468 216834021
2 2006-10-02 231158527 234565250 236004109 231467851 230100639
230079907 230734064
3 2006-10-03 282062314 285427832 286372163 282532055 280930498
281155966 281124614
After using
write.table(FinalOutput, paste("ModelComparison.csv", sep =
''), sep = ',')
the out put I get on the csv is
GasDays 31/03/2011 30/09/2010 31/10/2010 30/11/2010
31/12/2010 31/01/2011 28/02/2011 31/03/2011
1 01/10/2006 217303553.3 221205032.6
222824638.7 217016510.8
216093460 216477467.9 216834021 217303553.3
2 02/10/2006 231158527.1 234565249.7
236004108.7 231467850.7 230100639.1 230079907.4
230734064.4 231158527.1
3 03/10/2006 282062314.5 285427831.6
286372163 282532055.2 280930497.7
281155966 281124613.8 282062314.5
so essentially one column full of 1,2,3, ... is added to the file when
saving it.
Can someone pelase help me to get rid of it?
Thanks
Paolo

[R] Column of numbers added to dataframe when saving with read.csv
You need to add row.names=FALSE to your write.table() statement. This and other useful options are documented in the help. And you'll notice that that first column of row names appears in your R output as well.
