Fill down a new column in data frame with a number
Hi,
I am a begginer in R programming.
I am traying to create a a column in my data frame filled down with a
number.
> df$newcolumn <- number
How can I do it? I am considering use rep() but in this case it is
necessary know the number of rows in each data base that I have and I would
like to do it in a faster ( and more elegant) way.
