Sorry for mailing to you personally...
for types
read.csv(file.choose())
freqTable = table(types)
pie(freqTable)
##example for some data
temp = data.frame(types = 1:10)
pie(table(temp))

Hi all,
I am looking to create a pie chart from a given column in a .csv file.
My class variables are as follows:
entry_type, uniquekey, types, title, url, abstract, journal,
author, month,
year, howpublished
So say I want to export a pie chart that groups together all entries under
'types' e.g. 3 x statistics 2x education etc. Im looking to have a piechart
represent this graphically that shows which type of entry is in most
frequently. Preferably I'd like to export to a PDF chart and while I can do
this by typing variables directly into the R console, I cannot manage it
from a .csv file.
If you cannot help me with this specific problem, just knowing how to create
a generic pie chart would be a great help.
This is part of my final software project which is due in one week. I would
very much appreciate any help.
Many thanks in advance
