...g algorithm to choose for your classification problem? Of course, if you really care about accuracy, your best bet is to test out a couple different ones (making sure to try different parameters within each algorithm as well), and select the best one by cross-validation.

How to add texture to fill colors in ggplot2
...: make the border on one bar darker than the others using R
EDIT: I've finally found time to give a brief example of this hack that allows at least 3 types of basic pattern in ggplot2. The code:
Example.Data<- data.frame(matrix(vector(), 0, 3, dimnames=list(c(), c("Value", "Variable", "Fill")))...
How to do joins in LINQ on multiple fields in single join
...xplain that reason.
If you want to do something other than what you originally asked for, please give an example of what you really want to do.
EDIT: Responding to the edit in the question: yes, to do a "date range" join, you need to use a where clause instead. They're semantically equivalent real...
