I have a csv file that contains weather observation (rows) by days (in
I open using:
> temp = read.csv("Weather.csv", sep=",")
X X1.Jan X2.Jan X3.Jan X4.Jan
1 Min 2 3 4 1
2 Max 6 10 8 6
3 Forecast Min 3 1 1 3
4 Forecast Max 8 7 4 9
If I type
The same command on
> y = matrix(1:21, ncol=7)
Works because the data is in a matrix. I believe R stores the data from the
csv file as a data.frame with these annoying headers. So how do I convert
the data from my csv file into a matrix?
I tried as.matrix but it did not help.
Many many thanks!
