There are 7 rows since this is probably a data frame and each column
in a dataframe (or a matrix in this case) all have the same number of
rows. I think what you want is to 'sum' the number of times a
condition is met; this might come closer to what you were expecting:
sum(weekly$a != 0)

Hi all:
Can someone help me count the
number of rows with values in
colum "a" only. assume the name
of my dataframe is "weekly"
I was trying
i<- nrows(weekly$a)
i
but returns 7 when it should
be 4. Thanks
