simple statistics with R
October 03, 2009 at 03:43 PM | categories: Uncategorizedi'm learning a new statistics language called R and it's pretty cool.
make a vector ...
1 2 | > c(3,1,4,1,5,9,2,6,5,3,5,8) [1] 3 1 4 1 5 9 2 6 5 3 5 8 |
turn it into a frequency table ...
1 2 3 | > table(c(3,1,4,1,5,9,2,6,5,3,5,8)) 1 2 3 4 5 6 8 9 2 1 2 1 3 1 1 1 |
sort by frequency ...
1 2 3 | > sort(table(c(3,1,4,1,5,9,2,6,5,3,5,8))) 2 4 6 8 9 1 3 5 1 1 1 1 1 2 2 3 |
and plot!
1 | > barplot(sort(table(c(3,1,4,1,5,9,2,6,5,3,5,8)))) |
so simple!
