Good morning,
I've been dabbling in R, so my knowledge has quite a few holes in it. I'm
hoping that this has a simple answer and just falls into one of those holes.
I have a table of percentages that I want to display as a barchart. Groups
1-4 in columns and Variables 1-5 in rows, with the percentage of each group
expressing interest in each variable in the cells. In Excel I just
highlight the data and make a chart and it pops out with four bars
(representing the cell values for each group) for each of the five
variables.
What I think I need to do is barplot([mydata], beside=TRUE, [labels, colors,
and text]), but I get the error "'height' must be a vector or a matrix" when
I do this. When I try this using one of the preloaded datasets (VADeaths) I
can get the graph I'm looking for, but not when I read.csv my dataset.
Does anyone know what I'm doing wrong? Can anyone point me in the right
direction?
Thanks,
Phillip
