Hi All,
this is my first mail here.
I'm trying to plot a multiline chart grouping values with no success. I have
read a lot in the official Wiki and also searched via Google, but I did not
find anything.
I'm importing some data from a cvs file. Here is a sample:
YEAR,AREA,CASES
1988,CONTRACTS,286
1988,INTERNATIONAL,189
1988,FAMILY,385
1988,TAXATION,177
1989,CONTRACTS,233
1989,INTERNATIONAL,431
1989,FAMILY,425
1989,TAXATION,201
1990,CONTRACTS,190
1990,INTERNATIONAL,302
1990,FAMILY,303
1990,TAXATION,209
...
"t <- read.csv("file.csv", header=TRUE)"
So far so good...
But the problem is: I'd like to create a multiline plot, one line per AREA,
showing the evolution of the number of CASES per YEAR.
I know how to do it in Excel, using a Pivot Table. But I'm trying hard to do
the same with R but I have no idea on how to do it.
Can someone help me?
Thanks in advanced
