R help - Sep 2015 - Exporting column names with spaces with write.csv() XXXX

Hi all,

I have a number of columns with spaces in the column names exactly as
I want them in R. When I go to export the data table to csv using
write.csv(), the fn adds periods in place of the spaces.

Is there a way to suppress the addition of the periods?

Thanks,

Dan

Reproducible example, please.

Hi Dan,
I don't get this behavior with R-3.2.2:

da.df<-data.frame(1:3,4:6)
names(da.df)<-c("no good","no good at
all")
> da.df
  no good no good at all
1       1              4
2       2              5
3       3              6
write.csv(da.df,file="gloop.csv",row.names=FALSE)

gives me this:

"no good","no good at all"
1,4
2,5
3,6

Are you sure that R didn't add the periods when you created the data frame?
They would then be written into the CSV file.

...or, when trying to read it back into R,

read.csv(header = TRUE, text = '
"no good","no good at all"
1,4
2,5
3,6')

  no.good no.good.at.all
1       1              4
2       2              5
3       3              6


read.csv(header = TRUE, check.names = FALSE, text = '
"no good","no good at all"
1,4
2,5
3,6')

  no good no good at all
1       1              4
2       2              5
3       3              6


Thanks for the MWE, Jim.
