I would then just change it using names()
For example:
> names(df) <- c("letter", "Freq")
> df
letter Freq
a a 1
b b 1
c c 1
If you prefer having nothing, I don't really know how to do it because I
couldn't use my dataframes without column names!

Dear list,
Sorry, I did not explain myself very well.
I want to obtain a data.frame like this :
Freq
a 1
b 1
c 1
This data.frame contains just one column (Freq) and each row is named.
But when I use this code :
df<- as.data.frame(t)
or this code :
df<- as.data.frame(t, row.names(t))
The "a" column remains.
Thanks,
Carlos

Dear list,
I have a contingency table :
a<- letters[1:3]
t<- table(a)
I'm looking for a way to transform this table into data frame, as
follows :
Freq
a 1
b 1
c 1
I used :
df<- as.data.frame(t, row.names = names(t))
But, this function do not remove the duplicated column. Do you know the
solution ?
You probably do not distinct between columns of data frame and row names
of data frame. From what you told us it is not clear which one you want to
keep
if row names use
as.data.frame(as.matrix(t, row.names = names(t)))
if you want to keep column
as.data.frame(t)
shall suffice.
Row names is not a data frame column.
Regards
Petr
Thanks in advance,
Carlos
