Hello,
That is not a row, what you seem to have is an object of class
"matrix" and when it's printed it prints the column names or [,1]
[,2] etc if there aren't any colnames. So your matrix has just one
column and 4 rows with rownames 'date', 'Peeps', 'days', 'worn'.
Hope this helps,
R
Hello,
I am simply trying to remove the [,1] row from a matrix. I tried to
search Google to see if I could find how that is removed, but could
not find a way to do it.
So I have the following:
[,1]
date 2019-7-01
Peeps 5
days 7
worn 9
this is wha
4 matches
