Hi, I am a relative newbie to R, so thanks in advance for the patience.
I am interesting in changing a table with year data into a format that
is friendlier for making bar charts. I currently have a table with the
same year appearing a number of times as separate rows. I want to
change this so that each row is equivalent to a particular year.
Here is an example of my current format:
TAX YEAR NUMBER
A 2000 2
A 2001 2
A 2002 3
A 2003 1
B 2000 3
B 2001 4
B 2002 3
B 2004 2
A<-data.frame(c("A", "A", "A", "A", "B","B","B","B"),
c(2000,2001,2002,2003,2000,2001,2002,2004), c(2,2,3,1,3,4,3,2))
colnames(A) = c("TAX", "YEAR", "NUMBER")
I want to Change this to the following:
YEAR A B
2000 2 3
2001 2 4
2002 3 3
2003 1 0
2004 0 2
Any help would be appreciated!
Of course, while I am posting, I'll also ask for any tips for creating
a barchart with the X axis being "YEAR".
Thanks for the time
Mike
