Hi,
as a bloody R beginner I failed to solve the probably simple problem
to create a barplot of the following data read from a file
Year A B C
2000 4 3 0
2001 2 1 3
2002 1 2 5
The Barplot should look like
5 | C
4 | A C
3 | AB C C
2 | AB A C BC
1 | AB ABC ABC
+------------------
2000 2001 2002
(well, something like that - the colors are encoded as letters in this
ASCII-graphics - assume the coloring / shading as usual).
My problem is that if I read the table using
data <- read.table(file='data.dat', sep = '\t', fill=TRUE, header=TRUE )
everything looks is read as expected if I try
data
but I have no idea how to separate the Matrix (A B C) to specify the
height parameter of barplot as a matrix and the names.arg parameter
for the inscription. Whatever I tried I get
'height' must be a vector or a matrix
and I have no idea to do this right. So I think I'm just facing a
data conversion problem and have to turn data[['Year']] into a vector
and the remaining table into a matrix.
I guess this is a really simple question - but I failed to find a
solution.
Kind regards
Andreas.
