问题
I would like to store the contents of my data frame into a .csv file without the names of columns. I use the following piece of code,
write.csv(cur_data,new_file, row.names = F, col.names=F)
The resulting file looks like this,
"V1","V2"
-0.02868862,5.442283e-11
-0.03359281,7.669754e-12
-0.03801883,-1.497323e-10
-0.04320051,-6.557672e-11
However I would like to have the file in the following format,
-0.02868862,5.442283e-11
-0.03359281,7.669754e-12
-0.03801883,-1.497323e-10
-0.04320051,-6.557672e-11
I don't understand why the the col.names parameter in the code is not taken into consideration
回答1:
Dont use write.csv, use write.table
write.table( <yourdf>, sep=",", col.names=FALSE)
You cannot change many settings in write.csv -- the arguments are just there as a reminder to the user. From the documentation:
These wrappers are deliberately inflexible: they are designed to ensure that the correct conventions are used to write a valid file. Attempts to change append, col.names, sep, dec or qmethod are ignored
